The Digital single lens mirrorless camera (DSLM) purchase guide

The Digital single lens mirrorless camera (DSLM) purchase guide


The DSLM; for a couple of years it has been changing the photography market. What started out as a poor SLT attempt developed into a completely new and booming market? The market for DSLMs (D igital S ingle L ens M irrorless) or system cameras.

These are now available for every budget and many manufacturers now have a mirrorless camera in their portfolio. But should you buy a mirrorless camera? Does it have any advantages over DSLRs ? That and much more is the content of this page and finally I will show you a few models that I would recommend.

What is a system camera / DSLM?

There are two types of system cameras, with and without mirrors. The system cameras with mirrors are called SLRs and those without are called mirrorless. Sounds logical, doesn’t it? The mirror in the DSLR is historical and comes from a time without image sensors. The system has been perfected over decades. But for a few years now, DSLMs have been picking up. Teething problems are being eradicated more and more and many photographers are seeing a new alternative that offers many advantages over the old DSLR cameras.

The mirrorless camera / DSLM in detail

Height and weight

Many see an enormous advantage here. The DSLM lacks the mirror and as you can see in the example above, this saves space and of course weight. That is why the mirrorless cameras are much smaller and lighter. But they are still bound by certain limits. They are not as small as compact cameras. This is simply not possible with interchangeable lenses and large sensors. But they are still smaller than the DSLRs and therefore more mobile and inconspicuous.

Lenses

This is a special feature of DSLMs that you should definitely not forget. Other lens connections are used that allow smaller lenses, but they are not that small. There are certain limits that are physically given and specify a certain size. If you only buy these cameras because you want something as small and portable as possible, you should look around for a bridge or compact camera .

Ergonomics

Ergonomics is probably the first thing anyone who is switching from a DSLR to a DSLM should notice. The manufacturers try to make this as similar as possible, but it is simply a different feeling that can seem strange, especially with long-term DSLR users. In direct comparison to an SLR camera, I find the DSLMs to get used to at first. They are just small and lie better in the hand of one than the other. In my opinion, many manufacturers simply have too many buttons on the small housing, which makes operation a challenge.

There is only one option here: try it out. I recommend that anyway before you buy a new camera. DSLM cameras come in different forms. Very large, such as the Sony A3 or Canon EOS R, but also very small such as the Sony A6000 or Canon EOS M50. Depending on the model, you have an electronic viewfinder or just the display to look at your pictures. In any case, try out what suits you and what suits your type of photography.

Electronic viewfinder

A DSLM or system camera takes photos with an electronic viewfinder or the display. This means that the viewfinder does not have a direct optical connection to the subject like the DSLR, but a display. It is like looking at the finished image through the viewfinder.

The electronic viewfinder offers several advantages:

  • Image preview: You get a direct idea of ​​your photo and actually see the finished image before you press the shutter release. If you now change the settings on your camera: for example , closing the aperture or increasing the ISO value , the image changes immediately and you can judge whether you like the photo or not. You can also see the picture in the viewfinder after you’ve taken it. So it’s a second display that works just like your large camera display. The advantage, however, is that you can use it without being distracted by the sun.
  • Exposure aids: Because our EVF is a display, we can use many aids that the optical viewfinder cannot offer us. We can show a histogram , use an overexposure warning and much more … You can see immediately if your camera is not doing something the way you want.
  • Manual focus: With manual focus, we can use the focus peaking to see where our focus is and even zoom into the image. A real help for manual focusing.
  • Much more: Since you can show almost everything in the displays, there are no limits to the manufacturers. Water cars, grids for image creation, image styles and much more is possible.

Now I’ve written so many great things about the electronic viewfinder that I would of course like to point out a few negative points. Because the electronic viewfinder naturally always has to be supplied with power. This should not be ignored with some models and some cameras have extreme problems with high power consumption and thus a short battery life. Also, for many photographers it is not pleasant to constantly look at a display (myself included). It’s a completely different feeling to actually see the subject instead of just being shown it. The cameras are getting better and better here, but sometimes they are lagging behind due to delayed display (the display is delayed compared to reality).

I would like to add one point for those who like to take photos at night (long exposure ). If you take a picture with the DSLR, you have the light intensity of your own eye available. With the DSLM, the display in the viewfinder depends on the power of the camera. That may not sound too bad, but there are a few moments when I would have wished for my DSLR…

If you are not sure which viewfinder is right for you, I recommend that you test both of them once and take a closer look. I find the DSLR to be much more pleasant, especially in series pictures and when photographing fast subjects, but something different suits everyone.

Autofocus

There are several options when focusing with a mirrorless camera (DSLM). You may be familiar with the first option from the DSLR. If you switch to live view here (i.e. using the display), the autofocus becomes significantly slower. This is because the camera is using the contrast AF. This simply shifts the focus until the image has the highest possible contrast has. This is very precise, but unfortunately a lot of time is lost in trying out and “pumping” the focus. That’s why there is still phase autofocus, which was reserved for DSLRs for a long time. Here, two sensors compare the light (phase) falling into the lens from different angles and thus know from the first measurement what needs to be changed on the lens to focus. Cool right?

Most modern DSLM cameras use a combination of these two methods in order to be able to focus both quickly and precisely. If you use a modern DSLM camera, you should make sure that it supports phase or hybrid autofocus.

Picture quality

We come to the last point, and in my opinion the most important point. The image quality. In terms of image quality, the system camera is in no way inferior to the SLR. Of course, not all cameras are the same here, but in most cases you don’t have to worry that you have something worse just because you are using a different system. Most cameras even have the same image sensors installed (Sony makes sensors for some Nikon cameras and Canon has installed the same sensor in the 5D4 & R and the 6D2 & Rp). There is only one real way you can be sure that the quality will meet your expectations. Test the camera 🙂

Choice of lenses

From my point of view, this is a major negative point. It is not the case with all manufacturers that the newer the manufacturer is in the DSLM market, the more likely it is that the choice of lenses is limited. For decades it took a long time to develop a wide variety of lenses for DSLR cameras. This has only just begun with DSLMs and although lenses are already on the market, one only starts with the most important ones at the beginning. One or the other special lens may not be found here yet. Of course there are adapters that allow the use of DSLR lenses, but I have made the experience that it often leads to problems (slow autofocus etc.).

There are always new lenses on the market, but keep in mind that you may not find everything here and that you have to expect limitations.

Is the mirrorless camera or system camera right for you?

This is of course a question that cannot be answered easily. I always recommend trying out the camera beforehand. But I would like to give you a little support along the way that should help you with your decision.

The DSLM is interesting for you if the following points apply:

  • You’re used to smaller cameras – that  was the first thing I didn’t like about the DSLM cameras. The size. Ok, I also come from the DSLR segment and am used to large cameras with battery handles. However, if you’ve been taking photos with a compact camera or mobile phone the whole time, then the size of the DSLM is perfect for you.
  • You can handle the digital viewfinder – the electronic viewfinder is not for everyone. Some have problems seeing everything on a display / digital viewfinder. If that is not a problem for you, then you can use the mirrorless camera.
  • You want to try something new – that was one of the reasons why I keep getting a DSLM for different jobs. It’s just fun to use a different camera. Maybe it fits better than the current one? Just keep in mind that you don’t need a new camera straight away because it can do one thing a little better than the current one.
  • Video – Yes, the site is actually called Learn Photography, but especially when it comes to video I would prefer the DSLM to the DSLR and any other camera. They’re small, they’re incredibly powerful, and you can’t beat the autofocus when filming.

Buy recommendations

Entry level DSLM

Canon EOS M50 * – Sony Alpha 5000 * – Olympus PEN E-PL9 * – Panasonic LUMIX G *

Advanced DSLM

The compact camera – camera purchase advice

The compact camera - camera purchase advice

Which camera should I buy? One of the most frequently asked questions in the beginning of a photographer and beyond. On this page I’ll show you why compact cameras are the right choice for you; or not. Let’s go 😉

1 What is a compact camera?

2 The advantages of a compact camera

3 disadvantages of compact cameras

4 Who is the compact camera for?

What is a compact camera?

The compact camera is, as its name suggests, compact, i.e. very small and handy. All components are designed to be as small and light as possible. A small flash is usually built into the camera housing and the lenses are specially developed for the smaller cameras and are also smaller. They are mostly designed to turn them on and just get started. For this reason, the lens, which cannot always be changed, is designed to simply photograph everything. Some cameras offer further setting options, but the primary focus is often the simple “point and shoot”. Hold on and release.

The advantages of a compact camera

Mobility

Regardless of whether it is a pocket, a backpack or simply in the hand the compact camera simply fits everywhere. You can just take them with you wherever you go. Due to its small size and hardly any weight, it is extremely mobile and no problem even on long journeys. This is a real advantage compared to a SLR camera 🙂

Service

These cameras are designed to be operated by laypeople and are therefore extremely easy and intuitive to use. They are entry-level cameras and although you can control aperture , ISO and exposure time in some models , you will look in vain for one or the other professional function. But that’s not bad, because it makes operation easier and one must not forget: the cameras are not made for this.

Universal

A compact camera with its fixed lens can be used universally in all situations. With a DSLR or DSLM you would have to take several lenses with you, such as a macro lens, a wide angle lens, a telephoto lens, etc … The compact camera combines all of this in one lens. Super zoom and macro are functions that can be found with these cameras. So you are prepared for every situation and it is not necessary to change the lens.

Depth of field

Now it’s getting a bit technical. Compact cameras have a very small sensor. The size of the image sensor has an influence on the focus area. This means that with a small image sensor you can get a large area of ​​focus. If you want to have as much sharpness as possible in the pictures, you need a small image sensor. Architecture and landscapes can be reproduced very well, while cameras with a larger image sensor would have to close the aperture significantly and therefore need more light.

Price

We’re still with the small image sensor. Because small sensors are cheaper to manufacture. There are also devices in the field of compact cameras that exceed £ 2000, but these also have a large image sensor. The purchase and entry into photography is extremely cheap with these cameras, and the enormous spread of smartphones further lowers the price.

Disadvantages of compact cameras

Of course the world is not perfect. Everything has its disadvantages and so of course compact cameras too. Below I have listed the most important ones for you.

Limited image quality

Compact cameras are all-rounders. They can do anything, but that also means they are not really good at anything. Anyone who can do a lot, offers everything and that at a reasonable price has to compromise somewhere. In this case, the small image sensor is to blame. Compared to DSLR / DSLM cameras, you have to compromise on sharpness, dynamic range and the ability to take photos in the dark ( ISO noise). Especially in demanding situations it is very difficult to achieve useful results for these small karmas. Taking photos freehand in the dark? Not a very good idea.

Limited quality of the lens

I already said that you always have to cut corners with an all-rounder. The same goes for the lens. The size of the lens and the usually enormous zoom result in a loss of sharpness, vignetting and chromatic aberration. In addition, every light reflex is reflected across the lens and makes photography almost impossible in some situations. Of course, I am comparing € 1,000 lenses with a £100 camera-lens combination, but you should know what you’re getting yourself into … It gets better (it always gets better)

Handling

A problem that I’ve had with many DSLM and bring cameras: They are simply too small. That makes it very mobile, but it is also demanding to use the small buttons and it happens again and again that you press 3 buttons at the same time. The cameras also have no eyepiece and you have to rely completely on the display. This can work, but in strong sunlight this display is almost useless.

Lens change

There are compact cameras in the higher-priced segment that offer the option of changing the lens. However, I now assume that you are using a device that does not offer this functionality. A lens that is permanently installed has advantages, but an upgrade or a change is simply not possible here. As a photographer you always want to adapt the camera to the given situation and that only works semi-well here.

Who is the compact camera for?

I can answer this question very easily. For everyone who wants a camera that just works. You don’t want to deal with many setting options? Just hold on, pull the trigger and receive a photo as a memento? Then this type of camera is perfect for you. It is small, light, universally applicable and also inexpensive. However, if you now expect the ultimate camera that perfectly photographs every situation at the push of a button, then you will be more likely to be disappointed. These cameras have technical limitations and are perfect for someone who just wants to capture memories.

The Digital single-lens reflex (DSLR) camera purchase advice

The camera with the most widespread use is the single-lens reflex camera or DSLR. It is suitable for a large number of photographers and can be used both in the beginner area and in the professional environment. In this article we will clarify whether a SLR camera is worthwhile for you or not. Finally, I would like to recommend a few DSLRs that are particularly suitable for beginners, but also for advanced users and professionals. But remember: a better camera doesn’t make a better photographer. It doesn’t hurt to start small and adapt your equipment to your experience. Your driving school car didn’t have 800PS either 😉

How does a DSLR work?

The mirror reflex camera is a camera that works with a mirror. DSLR stands for D igital S ingle- L ens R eflex. The mirror comes from the analog era, because back then you had to be able to look through the lens without exposing the film. The mirror is thus the switch between the optical viewfinder and the image sensor.

If the DSLR camera is switched off (or has nothing to do), the mirror is also folded down and we can look through the lens through our viewfinder. The moment we take a photo, the mirror folds up, covers the viewfinder and releases the image sensor. Then it folds down again. That is the reason why you sometimes see nothing with DSLRs while taking pictures.

Tips for taking photos with the DSLR

I would definitely advise you to use the viewfinder, although many cameras can also show the image live on the display thanks to digital technology. The disadvantage of the display, however, is that it is reflective and sometimes makes it difficult to see something. Of course, we don’t have that with the viewfinder 😉 these cameras are also built to take photos with the viewfinder. The complete autofocus and the power of these cameras are in here and it is definitely worth keeping the display outside.

 Advantages of the SLR camera

high image quality

To put it simply, a larger image sensor often results in better image quality. Well, the smallest image sensor in a DSLR is an APS-C sensor. These sensors are far superior to those of compact cameras. Due to their large size, they have a higher resolution or can handle more megapixels much better than their smaller colleagues from the compact camera. The reason for this is that with a larger sensor, more light per pixel arrives and that ensures a significantly better quality, especially in poor lighting conditions.

In good situations, all cameras can deliver a good result, but in every one? This is something demanding, which usually requires appropriate equipment.

Versatility of the DSLR

An SLR can do everything. Due to the possibility of interchangeable lenses and the almost endless setting options, we can use them in every area, which is also the reason that they can be found in every area. By screwing on another lens, we can bring distant subjects closer or capture gigantic landscapes in a single photo. The setting options of the DSLR are not only aperture , ISO and exposure time , but also white balance , autofocus and so much more. As a result, they are definitely superior to compact cameras, which were made for everything, but which cannot be specialized in one particular area.

Battery life

I still compare the subject with compact cameras, because DSLRs and DSLMs represent the next step after a compact camera or smartphone. The battery life is definitely enormous. How long can your cell phone or compact camera run before you need a new one? For me it is 7-8 hours (with two rechargeable batteries in the battery grip) and up to 4000 photos. The whole thing depends a bit on the situation, but many should realize that it is significantly more than what is possible with cheap cameras. So a big plus for the DSLR.

Speed

Probably the most important point from my point of view. So as a professional you have completely different demands on the camera. But even for beginners it is a huge advantage if the camera does not have to think for 1-2 seconds after triggering before we can look at a picture, but if everything is displayed immediately and live. I’m not talking about as many pictures as possible in the serial picture, but about general handling. Do you always want to wait a moment for a picture to appear? Or until the camera has finally written the image to the memory card? Probably not … But there is more, because the autofocus is of course much faster and more reliable. Setting the focus in milliseconds ensures that you really don’t miss any more moments!

Lenses

Maybe someone knows this well-known picture, which shows Canon’s lens park. This gigantic mass of lenses also gives us an incredible number of possibilities. There is a suitable lens for every situation, so nothing is left to be desired. What is often solved with an extreme zoom lens in compact cameras can now be solved with a variety of specialized lenses. But of course you don’t always have to go to the actual manufacturer of the camera if you want the right lens. You can also work with third-party manufacturers such as Tamron or Sigma. These offer a wonderful and, above all, often cheaper alternative.

Disadvantages of the DSLR

Nothing is perfect. Of course, the SLR camera also has disadvantages and I’ll show you a few reasons why you shouldn’t use DLSRs right away.

Weight and height

Please do not get me wrong. There are also small lenses and small DSLR cameras, but for many this factor is crucial. Imagine you are planning a vacation and you have to prevent a camera with 3 lenses in your luggage … A compact camera would be tempting. For example: a good full frame DSLR with a standard lens.

  • Canon 700d + KIT: approx. 800g
  • Canon 6d II + 50 1.2 + 35 1.4 + 24-70 2.8: 2.8 kg

These are all exemplary values ​​now, but larger cameras and lenses ensure that they take up more space and of course additional weight. It doesn’t really matter whether you use the DSLR or a system camera (DSLM). The DSLM is slightly ahead here, but in the end that doesn’t mean much. You have to be aware that you have a big and heavy camera with you.

Your own claim

This is something that I noticed again and again on my photo trips. When I travel with a DSLR, I need to take good photos. Over time you start to professionalize everything and look for the perfect photo. After all, a huge camera was dragged around with you all the time that cost several thousand yours. So why should you photograph something that you could have photographed with your mobile phone? Maybe it’s just me, but it can happen to you that you develop too high demands on your pictures and start to forget the actual memories and just stop taking those typical mobile phone photos.

Who should buy a DSLR?

A DLSR is not for everyone. If you are looking for a point and shoot camera, you should go for a compact camera. We are in an area where our purchase was unnecessary if we did not capitalize on the potential of this camera. So who is an SLR camera for?

  • Ambitious beginners who want a lot of performance for little money should use a DSLR or DSLM.
  • If you want a camera system that you can upgrade easily. (with new lenses or purchased lenses fit on new cameras again)
  • You are looking for an extremely wide range of accessories. Because the DSLR / DSLM market is extremely large and there is actually nothing that does not exist 😉
  • You want to rely on reliability and speed.

Some buy recommendations

Entry-level DSLRs

If you are looking for a cheap entry into DSLRs, the three-digit models from Canon or Nikon are very well served. Here you can get the models even cheaper if you buy older used ones. Canon’s 650d is still a good camera today!

Canon cameras with KIT lens: Canon 2000D * – Canon 1300D *  – Canon 800D *

Nikon cameras with KIT lens: Nikon D5300 * – Nikon D5100 *

Sony cameras with KIT lens: Sony Alpha 68 *

Advanced DSLRS

Canon camera with KIT lens: Canon 77D *

Nikon camera with KIT lens: Nikon D7200 *

Professional DSLRs with full frame sensors

The exposure time in photography

The exposure time in photography

The exposure time or the shutter speed defines how long the shutter of the camera remains open. This has several influences on our image, such as brightness and motion blur.

Basics of exposure time

The exposure time defines how long light falls into the camera. This happens either through a mechanical lock that releases the image sensor when triggered, or it is electronically simulated. That depends on the type of camera.

As a photographer, you can control the exposure time and use this both to expose a photo correctly and to create creative effects in the images. Depending on whether you expose long or short.

The exposure time is usually given in fractions of a second (e.g. 1/125) or in whole seconds (2 ″ for two seconds) if this is necessary. But when do we speak of a short and when of a long exposure time ?

Normal cameras can expose between 30 seconds and 1/4000 of a second. If your camera can’t, don’t worry. These are extreme values ​​that are rarely used. You can orientate yourself on a value from the film industry. These use 1/48 of a second to expose the individual frames of a film. Applied to photography, this is a more normal guideline. It’s not very fast, but neither is it very slow. This exposure time ensures that, although motion blur can be perceived, i.e. motion in the image can be blurred, the motionless is mostly frozen.

Influence on the picture

Brightness

The exposure time has two influences on the image. On the one hand, it controls the brightness.
This means that with a long exposure time you let a lot of light fall into the camera and the picture becomes brighter. With a short one, less light falls into the camera and the picture becomes dark.
Beginners usually don’t notice much of this, as time is only one of three values ​​that control the brightness of a photo. However, you can also turn it around. If I want a short exposure time I need a lot of light. If I want to take long exposures, this is often not possible with lots of light. Too much light falls into the camera and the image would be too bright.

Motion blur

Everyone has probably blurred a picture at some point. This is motion blur. This occurs when something moves too fast for the currently set exposure time . That can be our subject as well as the camera itself. The motion blur depends on the speed of our subject. Everyone moves. You can’t sit 100% still. But these movements are not as fast as a car, an animal or a bird. We have to adjust our attitude in order to keep up with our motive.

Fast exposure time

If we want to expose quickly, we speak of exposure times over 1/60 sec. Usually 1/200, 1/1000 or even shorter. This short time is necessary to either compensate for too much light (when it is very bright outside) or to freeze a fast subject. When we capture a fast movement that we cannot really perceive even with the human eye, we speak of freezing. It looks like time has stood still and a very short moment has been captured on a photo. For this we need a very short exposure time and have to adapt it to the speed of our subject. The faster the subject moves, the faster we have to expose.

Long exposure time

Long exposure is a great way to get creative, but be careful. Long exposure is not all that easy. We have a few things to consider.

We usually speak of a long exposure time when we expose longer than 1/50 of a second. These are usually values ​​in the seconds range, i.e. half a second, a whole or several seconds.

Use a tripod

By using a tripod, we avoid blurring. You can reduce or completely avoid the motion blur caused by your hand and the movement of the camera. There is a rule of thumb from when you should use a tripod.

Focal length / 1 = minimum exposure time

Your focal length is crucial for this. It can be compared to binoculars. It is often difficult to hold binoculars steady without a tripod, and so it is in photography. The further your lens is in the partial area, the more likely you are to blur your image. The phrase can now be transferred to the different focal lengths.

For example:

  • 30mm = 1/30 sec. Or faster
  • 50mm = 1/50 sec. Or faster
  • 200mm = 1/200 sec. Or faster

In addition to the tripod, you can also use this value further by holding your camera correctly or using an image stabilizer.

The long exposure effect

A long exposure time now ensures that we have more light available, for example, that we can take photos at night. On the other hand, it naturally creates motion blur, which we can use skillfully to blur elements of our image or even to make them disappear. Because everything that happens while our shutter is open is also recorded on the image sensor.

Set exposure time

The exposure time you can set in your camera with two options. On the one hand there is the manual mode. This is quite demanding for photography beginners, as all values ​​have to be set manually and of course it does not forgive any mistakes. The second option is the Av or S mode. With this you can set the exposure time and your camera takes care of the other values, such as aperture and ISO . You can first concentrate on one value and then go into the other setting options.

The ISO value of your camera

The ISO value of your camera

You must have already found a button or an ad with the label ISO on your camera. If you press it, you see a lot of numbers and maybe you don’t know what to set here. Don’t worry, that’s what today is about!

In addition to the exposure time and the aperture, the ISO value is probably the most important value in the exposure of your photo. It controls the brightness of your pictures, but also has other influences.

Origin & functionality

Originally, the ISO value comes from the sensitivity of analog films (ASA). This sensitivity was due to the different sizes of crystals used on the film. Large crystals could absorb more light, but created a so-called grain (noise). If small crystals were used, the film could absorb less light, but the grain became finer and finer and less visible to the eye.

But how does it work digitally now? After all, we can’t make the pixels on our image sensor bigger or smaller. Therefore there is a digital possibility to increase the ISO value. Usually every single pixel sends information to the camera. If this signal is too weak, the light received is too dark. Now we have to increase the sensitivity (the ISO value), which amplifies this signal. This allows the camera to perceive light much better, but unfortunately not only the light is amplified, but also the interference with the sensor and the electronics. We will see this later in the picture as image noise.

How does ISO affect our images?

This can be compared to the human eye. This can also see in the dark, but is then blinded by bright lights. It’s the same with your camera. If you have set the ISO value very high, every light, no matter how small, looks incredibly bright, but you can see with your camera in the dark.

Originally, the ISO value comes from the sensitivity of analog films (ASA). This sensitivity was due to the different sizes of the crystals used on the film. Large crystals could absorb more light, but created a so-called grain (noise). If small crystals were used, the film could absorb less light, but the grain became finer and finer and less visible to the eye.

But how does it work digitally now? After all, we can’t make the pixels on our image sensor bigger or smaller. Therefore there is a digital possibility to increase the ISO value. Usually every single pixel sends information to the camera. If this signal is too weak, the light received is too dark. Now we have to increase the sensitivity (the ISO value), which amplifies this signal. This allows the camera to perceive light much better, but unfortunately not only the light is amplified, but also the interferences of the sensor and the electronics. We will see this later in the picture as image noise.

With the ISO value this is the noise. Noise looks like someone has placed the smoking of a television picture over your photo. This effect is also known from many smartphone cameras that only show muddy pictures without sharpness in the dark.

This is because we perceive sharpness as micro-contrast. So as a small difference between light and dark. However, the edges between these areas are destroyed by noise, which is also a difference between light and dark.

The high ISO value (6400) ensures that you can see the stars, but the details in the grass are completely lost in the noise

How do I set the ISO value?

To set this value on the camera, simply press the ISO button . Then you can use the corresponding adjusting wheel to check how high or low the value should be set.

Like exposure time and aperture , the ISO value is based on aperture steps. In addition, it is based on the power of 2, which doesn’t make it all that easy. But I have an example that might make it easier.

Every step to the right (higher value) makes the picture twice as bright as before and every step to the left makes it half as bright. Got it? Well! Because there are also third steps that allow you to fine-tune the value.

So if you still have intermediate values ​​on your camera, do not worry: this is only for fine adjustment.

When do I use which ISO value

This is now a subject that a lot of completely misunderstand. Because the ISO value is nothing worse. It doesn’t always have to be kept so low that we avoid any noise. The ISO value should support you in your photography and with modern cameras the noise is also less and less.

My tip: Try to find out on your camera when the ISO noise is so strong that you can no longer use an image and when you don’t notice any differences. 

For me, it’s pretty easy with all my cameras: You can actually always use ISO 100-800 without seeing any noise anywhere. From ISO3200 everything should be treated with caution. This example can work for you, but it doesn’t have to.

Avoid image noise

Noise does not have to be a bad thing either – although this image is very noisy, you can still see enough details and can forgive the noise.

Do you now have to take photos in the dark and want to avoid the noise? Then I now have a few tips for you. First of all, a larger image sensor always ensures less noise, as the pixels on the sensor have significantly more space and can therefore absorb more light. But a new camera is not the universal solution. Better take a look at what can still be extracted from the other values. We have exposure time and aperture , which can possibly be set a little brighter and thus relieve the ISO value.

But be careful: it is better to take a noisy picture than a blurred or blurred one. Viewers of the picture are more forgiving of noise than blurred or even blurred pictures.

An alternative would be to take the photo in RAW and remove noise from the image. There are many image processing programs for this that can pick up the noise in the image. There are many possibilities here, you can find your own way.
