I performed a real-world test of four 35mm lenses on the Sony alpha 7 Mark II:
- Sony/Zeiss (Zony) 35mm f/2.8
- Zeiss 35mm f/2 Biogon M-mount
- Zeiss 35mm f/2 DIstagon F-mount
- Nikon 35mm f/2 Nikkor-D
The scene, wide open with all the lenses so you can get an idea of the light falloff towards the edges:
It’s a little surprising that the FE lens, designed for the camera, and operating a whole stop down from any of the others, has the worst falloff. None are particularly bad, though.
At f/2, in the center (the Zony is not represented here, since it doesn’t open that wide:
The Distagon wins.
In the upper right:
The Biogon is plagued with flare, and chromatic aberration,. The Nikkor is just soft. The Distagon is fine.
This is super helpful. Just wanted to say thanks for this! Good to see some corner tests of the 35mm ZM f2.
