The Sony A Mount 135mm f2.8 STF Lens is a unique lens in many ways. The most obvious difference compared to conventional lenses is the lack of AF. So why’s that ? The lens has a so-called apodisation optics using one APD element. APD elements resemble neutral density filters which become thicker the more you move towards the perimeter thus reducing the amount of light passing through. Out-of-focus circles are therefore (comparatively) defined in the center but are gradually loosing light towards the edges thus producing a very silky bokeh (out-of-focus blur) – the primary sense of existence of this lens.
