Summary: The Canon EF 24-85mm f/3.5-4.5 USM exhibited a quite mixed performance. On the upside the lens is very sharp with very little vignetting throughout the range. Unfortunately distortions at 24mm are pretty hefty as are chromatic aberrations.
Summary: Here's another case where it all depends on how you use it and what you expect. Personally, I like really sharp images. This means, I can photograph something that has a lot of detail and examine the corners of the image at 100 - 200% and "read" what's there.
Conclusion: Not a bad walking around lens in bright conditions or for general grab shots. Much better than kit 18-55, particularly stopped down. Want pin-sharp results throughout the zoom range and a usable f2.8? Time to shell out that extra $1,000 and get the 24-70L.
Pros: Light, inexpensive, good range, USM/FTM, produces decent images if not pushed to its limits.
Cons: Build quality a little weak, images soft wide open.
Conclusion: i wasn't very hot for this lens after reading some of the reviews but i really needed a light weight zoom for travelling. i tried this lens in a food studio session, and the results are not bad, though not as good compared to the other lens used, the 50mm 2.5 macro.
Conclusion: I bought this product one year ago in B&Hphotovideo in NY and I was quite happy then... But, When I brushed my skills in wedings and fashion division I understood that this is not a good glass for me niether for serious customers!!!
Pros: Light; inexpensive, fast AF, portrait lens at 85...
Cons: Vigneting at 24mm...even at 85 on the edges! 67 filter size, f/3,5-4,5 not so sharp for zoom standard at f/3,5- 8 etc...
Conclusion: This lens is a good standard zoom and surely a great improvement over any kit lenses. Wide open it is rather soft, but stopped down a bit it is really good. USM makes the AF fast and accurate.
