Summary: After read all the remarks and not liking this lens, I bought anyway. I dont know why some do not like this lens, it very quite, crisp and light. For a kit lens and a walking around lens. Go for it, some just or not happy with anything.
Conclusion: Recently I got the EF 28-90 F/4-5.6 II (non USM) as a present. Actually I didn't think I would be using this little lens, I did have a Sigma 24-70 F/2.8 EX DG altogether. But to my surprise this lens is a real killer. It's very, very lightweight.
Conclusion: I found this lens in Dubai.I cannot say I bouth it because seller gave me this lens free with a $200 dollar eos 30 film camera. I used this lens on my digital rebel.I was the worst image quality i have ever seen.I had also been using 18-50mm F3.5-5.6 because of my technical limitations but even...
Conclusion: It is not as bad as is often said, but I seem to have a good copy. For beginners on a limited budget who want to start with a 2nd hand DSLR like the old D30 (which I still can fully recommend if you can find it for $300-350!).
Pros: light, useful range, DC version is cheap and has silent & fast focusing like the USM. 10D focuses accurately with it. D30 likes it too, which it actually fits very well to because of the D30's 3Mp resolution. Good sharpness from f/6.3 onwards as long as you use it in the 35-80 mm range!
Cons: wobbly front element which rotates when focusing Forget the USM version (DC is cheaper & much more worth its lower price) Small DOF not possible because of small aperture. 28-35 and 80-90 mm range are clearly add-ons: poor sharpness, vignetting and distorsions
Conclusion: This was my first standard zoom lens. Bought it with my camera to save some money, but it's not worth the (even low) price. Most irritating was the flare that comes with it, even with the lenshood it was inavoidable. Pics are not very sharp, especially the ones in close-up.
Conclusion: I got this lense as a gift with my Elan 7 - my first SLR in 20 years. I shot a couple of dozen rolls with this lense and loved many of the pictures I got with it. It was only after getting my 10D and reading up on lenses that I realized this was a very cheap entry level zoom.
Pros: Very inexpensive, light and compact.
Cons: The image quality is pretty mediocre. The build is certainly cheap but what I would expect for the amount of money you're spending.
Conclusion: Bought this as my first canon lens for my first D-SLR. First few pictures I took with it seemed pretty good, until I started comparing them to other pictures. Focus is very soft, colors loose saturation, pictures just seem lifeless when taken with this lens.
