Conclusion: Some years ago we analyzed the Zeiss Planar T* 50mm f/1.4 on an APS-C DSLR and the results were truly impressive there. However, on a full format DSLR the performance leaves a bit to be desired actually. The lens is capable of delivering great results at medium aperture settings - no doubts - but it disappoints at f/1.4 and f/2 with a rather poor border/corner performance and generally reduced contrast.
Conclusion: The Zeiss Planar T* 50mm f/1.4 ZF is an anachronistic lens these days. It is fully manual both regarding focusing as well as aperture control on the lens. It is not even a perfect lens - the vignetting figures are in line with the rest of the gang and the level of distortions and CAs is even a little higher though still moderate in absolute terms. However, there`re at least two aspects that are definitely -not- moderate.
