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.
