Sounds like an opinion from someone who has never used Zeiss lenses and who doens't understand constraints that an SLR places on lens design.

The wide-angel Contax G lenses are extraordinary. The lack of a mirror box removes constraints that the SLR mirror box imposes. There is no Nikon wide angle lens that can compare to the 21mm Zeiss biogon. The flip side is that the Contax G-mount cameras aren't as versatile as an SLR.
