Zeiss 35mm 1.4 versus Samyang 35mm F1.4 on a full-frame camera

In this comparison on a Nikon D3x (full-frame), the Samyang 35mm f/1.4 is better than the Carl Zeiss Distagon T 35mm f/1.4 ZF2 in almost all respects, for a price 4 times lower. On a full-frame, the superiority of the Samyang is mainly due to its better homogeneity across the field.

Zeiss 35mm 1.4 versus Samyang 35mm F1.4 on an APS-C

In comparing these lenses on an APS-C, it’s interesting to note that with the smaller pixels of the APS-C sensor, the 2 lenses are much closer in term of performance. It will be interesting to see how these lenses behave on the new generation of 24-MPix APS-C sensors.
