Sony A7rII | Zeiss ZM 35mm 1.4 T* Distagon | f/1.4 | full resolution And is less of a problem with the subject close to the camera. This may only happen at certain focus distances. Same goes for the bridge on the right, whereas here the effect is even stronger, as the right part of the bridge is in fact also closer to the camera. Have a look at the tree branches on the left, where the one towards the border looks less out of focus. While in the center of the frame everything is alright the blur lessens towards the borders. This leads to two unfortunate causes: degraded across the frame sharpness:Īnd also somewhat undesirable rendering of the bokeh. There is also a reason I don’t like the term “corner smearing” : what actually happens with many lenses is that the corners are just in a different plane of focus than the center portion of the frame and naturally this problem goes away when stopping down. In my experience the difference between all the A7 cameras is negligible here. The glass is so thick that – in conjunction with the very steep light incidence of some wide angle lenses – it affects the light rays hitting the sensor. The corner smearing on the other hand happens mainly due to the thick (in comparison to the Leica M cameras and especially film, where there is none) filter stack in front of the sensor. Still, there are options to correct this like corner fix or by the use of gradients in Lightroom, which I did for this shot:īefore: Ultron 28mm 2.0 2.0 (green color cast uncorrected) | After: Ultron 28mm 2.0 2.0 (color cast corrected in LR with gradients) Still, even on A7s and A7rII you can see a color cast with certain lenses and stopping the lens down won’t help here, as can be seen in this example: Sony A7s | Jupiter-12 35mm 2.8 | f/11 | color cast | full resolution One also has to take into consideration that symmetrical wide angle lenses have quite strong vignetting by design and, in this regard, are inferior to the retrofocus designs which are mainly used in SLR wide angle lenses. The A7r is the worst, A7s(II) and A7rII fair much better.

color cast on the edges and in the cornersĬolor cast and vignetting are mainly influenced by the sensor design.

But let’s first recap, which problems might occur: There are quite significant differences between the different A7 cameras, or, to be precise, between the different sensors in the A7 cameras.

I had already covered this topic in detail in my Ultron 28mm 2.0 review, so I reused parts of it here.

Problems when using rangefinder wide angle lenses on A7 series cameras In case you are new to this topic I have again summarized the problems that might occur in the following section. We just want to spread the word and give fellow photographers around the globe the option to easily use their legacy rangefinder wide angle lenses up to their full potential.
