Oh man, I am such a fan of the new carl zeiss optics in both ZF and ZM mounts, while yes two completely different things, carl zeiss really is at the top of its game right now offering great stuff to photographers who actually know what it is they are getting with something like this. That test shot they have on there is shocking how even the performance is from corner to corner, and the distortion looks really really well controlled. If I had a nikon I would love to have this, but me being the stupid guy who hopes zeiss will put out a canon mount version of its lenses will just have to wait.
