Image quality
It is hard to fault the image quality of the 35mm f/1.4 lens. In the centre it is extremely sharp, with only a slight drop-off at the very edges when shooting at f/8. The corners aren’t as sharp when shooting wide open. However, at this maximum f/1.4 aperture the shallow depth of field is lovely, with smooth out-of-focus areas that blend into one another.
Vignetting is noticeable at most aperture settings, but at f/1.4 it is very prominent, with very dark corners to images. However, vignetting doesn’t concern me, and I am actually drawn to the vignetting on the f/1.4 aperture because, when combined with shallow depth of field and the level of contrast that the lens offers, images take on a very cinematic quality. If vignetting isn’t your thing, the camera does a good job of correcting JPEG images, or it is easily removed when converting raw files.
There is some red/cyan chromatic aberration visible when shooting at f/1.4, but by the time the lens is at f/4 it is significantly reduced, and it has gone by f/8. Again, I found that it is easily cleared up when editing raw images.
