    Cons: With the Canon version - none. The Nikon version has an aperture ring too narrow and too close to the body, making it fiddly to adjust.

    Pros: Excellent image quality on Canon 5DII. Very good wide open, even good into the corners, excellent at f2.8. I can't understand the previous comments about the IQ wide open - perhaps there was mis focus? I've tested it with live view, and to focus any manual lenses on the 5DII you need to use the S screen - the standard screen won't work! Very nice and small, with excellent hood. Does not flare, even when stressed.

    Summary: I love this focal length, and with a lens this good at this sort of size, the 5DII becomes an excellent quality convenient street camera. Not quite a Leica M9, but moving in that direction sizewise, and certainly much more versatile.

    Cons: - a little too much distortion - a modern prime should be sharper and/or contrastier wide open - stopped down (5.6) it is not better than comparable quality-zooms (e.g. 18-70 afs)

    Pros: -a reliable all-around performer -on film/fullframe: (for me) "perfect" angle of view - outstanding built quality and handling - small size especially with the compact sun-shade (inward-design) - good contrast and tonality

    Summary: the best all around prime for my film-loaded nikon
