DIWA Labs has tested the Carl Zeiss Planar T* 85mm f/1.4 ZE lens on a Canon EOS 5D Mark II DSLR camera body. This manual focusing lens is equipped with an all-electronic Canon EF mount making you able to set aperture in the camera.
DIWA Labs found out that the lens produce excellent results at medium and small apertures, but wide open it is a bit soft especially in the corners of the picture. This is due to the fact that the lens was tested on a full frame camera body.
