so i have a canon 40d with the kit lens (28-135). i want to get a second lens, but not sure what to get. so far i am thinking the 10-22 or (canon or sigma depending on how much cash i have at the time). i know i want wider shots, but that's about all thanks for the help
Why does a 28-135 come as a kit on a crop sensor camera?Weird. If that's really the case, then you need something like a 16-35, or 17-55 f2.8. That would give you a "normal" range of 28-80. Or, if you want to go wider, there are the lenses that you mentioned, which seem to be top notch, judging by the things i hear.
well on your camera assuming the crop factor is 1.6x then it would be 16-35 which is still good but its not a ff sensor so you're not going to get as wide. But if you are looking to go wider i would suggest the sigma my sigma 24-70 is great.
Welcome to the realm of the crop sensor. Multiply your focal lengths by 1.6 to get the actual reach of your lens. Your 28-135 is actually a pretty useless 45-216. Well, not useless, but you know what i mean. "Normal" kit lenses today are in the 18-55 range. Which, as i said, gives you 28-80. The 10-22 is Canon's equivalent of it's critically acclaimed 16-35, and gives exactly that range, in a slightly slower (3.5-4.5, instead of 2.8), but much cheaper and lighter package. Made specifically for crop sensor cameras, like your 40D. If i were you, i'd get a 17-55, f2.8. It's L grade, minus the weather sealing.
I have the same camera and the same dilemma. I'm saving for the EF-S 17-55 f/2.8 IS USM, as I don't see myself upgrading bodies any time soon. But I'm also low balling any EF-S 17-85MM f4-5.6 IS USM I see on Craigs List or E-Bay..
The 10-22 is about as wide as you are going to get as far as digital APS crop lenses go. If you do not intend on upgrading to a full-frame camera soon(why would you since you just got the 40D), than the EF-S 10-22 is an awesome lens. It is equivalent to a 16-35 on a regular camera. Pretty wide without going to a fish-eye lens. Review wise, the Canon model far exceeds the Sigma in image quality, build and edge sharpness. Always Sigma's weak point.
ahh why did canon make the 40d different from the 20d/5d? i want wiiide! haha although i think 16-35 would be a little bit more practical.
