Summary: I was very disappointed with this lens. It has a very cheap feel and the image quality was terrible. I was only able to test it with my Canon 20d and not with film. I couldn't believe how lousy it was, I had read some other reviews and they seemed positive. I tried it on a tripod and shot a variety of things text and 3-D objects and never could pull a sharp photo. I noticed that I had to use a lot more unsharp mask than normal to be useable.
Conclusion: I bought this lens about 18 months ago just for taking vacation-pics. I use it most of the time @24mm. Unfortunately the sharpness - especially in the corner - is even worse than a cheap 18-50 or a 28-90 (kit). I tested it @ 50mm against my 50/1.8 MK II. The latter is even @ f=1.8 sharper than the 24-85 stopped down! Probably I got a monday model!
Pros: small; cheap; good build quality; good zoom range; fast USA AF
Cons: no lens hood included; heavy vignetting wide open; performance (Sharpness) @24mm in the corner is insufficient;
Conclusion: I originally bought this lens with my EOS-300v film camera, I think it's the Kiss model elsewhere, and tranfered it to my drebel. Overal it takes good pictures. Bright and contrasty. The auto focus speed is good and focus lock is great, It has never hunted like the 75-300 IS usm does. I find it has some trouble in low light focus locks in situations where all my other lens will focus lock. At the 24 and 85mm ends its pretty soft.
Pros: Light weight, build quality.
Cons: Some distortion at wide and long ends, zoom creep, low light focus lock.
Conclusion: I've owned the lens for ages but only recently taken it back off the wife to try on my 1D2 as a general purpose lens. It doesn't do. It isn't fast or sharp enough at any aperture to get much out of the camera. The barrel is rather flimsy and is distinctly 'prosumer'. I can't recommend it. Buy a Tamron 28-75 2.8 instead, much better.
Pros: Light, reasonably cheap, good focal range
Cons: Slow, soft, pretty awful on digital actually
