Zeiss ZF 100mm f/2 Makro Planar vs Canon EF 100mm f/2.8L IS
Just posted to my Guide to Zeiss ZF / Zeiss ZE Lenses is my comparison with the Canon EF 100mm f/2.8L IS.
This comparison is expanded version of the one in DAP, it includes the full f/2 - f/11 aperture series, and is oriented to the Zeiss 100mm f/2 Makro-Planar.
