Excerpt: First impression of this lens is build quality. It does feels like an expensive lens. Focusing is so smooth. However if you like lightweight lens you may want to think about it. Regarding picture quality, I love its contrasty look. But beware when you shoot against light source.
Excerpt: Haven't used it much yet but I mostly liked the results.
I was a bit disappointed with the color fringing of darker objects against the highlights when viewed 100% but was able to cleanup that up with PS.
Excerpt: I use this prime with the Canon 7D and have no complaints whatsoever. Images are super-sharp and clear, color fidelity is outstanding. Manual focus is responsive and easy to do.
More importantly--and if you can afford the admittedly hefty price tag--this lens is a must for anyone interested in HDSLR...
Excerpt: This lens follows faithfully in the footsteps of Zeiss's heritage of excellent optics. (Based on photo-only use with a Canon 5DII, a 5D, and a 1DsIII.) This manual-focus lens captures razor-sharp, distortion-free images corner-to-corner.
Excerpt: Excellent contrast and color rendering. Sharpness is comparable to best Canon lenses like 135/2. Flare control is very good. This lens has moderate amount of chromatic aberration, which can be removed in some RAW converters, but some Zeiss ZE lenses have better correction.
Excerpt: This lens is a bit of a throwback, but a very good, sharp throwback. I appreciate my Canon 5D and the various L series lenses, but using this on my 5D is like going back in time to the heavier, well made, sharp-as-a-tack lenses of 25-30 years ago.
