Here is a gem of a lens... if Internet rumors can be trusted, even Zeiss admits that this is the sharpest lens they've ever made. Although I'm not a person that's big on sharpness, even I had to do a double-take when I viewed some of its images at 100% and marvel at its incredible details. Also, as much as I love a fast aperture, I felt it's a bit unnecessary on a wide angle lens since I'm most likely not going to try to isolate my subjects. I think it will take me a while to get use to this wide view, but I accept the challenge to incorporate more of the scene in my images.
