comment:First impressions:

Overall this is not an overly sharp lens but then ultra wides never come close to macro sharpness (to put it in perspective I only gave the CZ16-35 a rating of 4), it has similar centre sharpness to the minolta/tamron 17-35mm but softer in the corners. While it's the least sharp of the lenses I've compared it to the difference is not huge, buy this lens for types of shots it lets you take, it's those which give this lens the WOW factor. Equally don't go selling off this lens and expecting a huge jump in image quality short of going for the CZ.

Flare control is much better than I had expected better than the 20/24mm primes. The distortion control of this lens is amazing (especially at the long end) better than any of the other lenses I've compared it to.
