The ZF/ZF.2/ZE lines for Nikon and Canon are optically identical, so the comparison should be of interest to both Nikon and Canon shooters.
In the rarified world of high performance optics, the Zeiss is under-priced, believe it or not. See my handy list of ZE lenses for Canon and list of ZF lenses for Nikon. If you like the best, figure out a way to get one— invest in good optics and they’ll serve you well for a lifetime.
Note that the 100/2 Makro-Planar will be available in February in ZE mount for Canon and ZF.2 mount for Nikon, which I’ll note here in this blog. The existing ZF version remains available for Nikon of course (see notes). Thank you for using the links off this blog page when buying.
