I guess this is more of a general photography question than aviation per se. I have a Canon DSLR with a APS-C sensor. I have a 17-50mm lens already. I was looking at a 10-24mm lens for a little more width. In the opinion of experienced photographers, do you think I'd really notice the difference of that lens being 7mm wider? I don't understand the physics of how much that would increase my FOV. Anyone any hints or suggestions on this?
The difference between 10mm and 17mm is quite a lot, it's nearly twice as wide. I use my Sigma 10-20 EX quite a lot. It's great for cabin and flight deck photos as well as museums and travel. What is it you want to use it for? Do you require anything wider than 17mm?
Equipment: 2x Canon EOS 50D; Sigma 10-20 EX DC HSM, 50-500 EX APO DG, Canon 24-105 f/4 L, Speedlite 430EX

In my opinion if you own a crop sensor you need to have an UWA lens. Believe me, i tried to get out of buying one. Went to a 17-55 and thought I could have the best of both worlds. One a crop sensor 17MM is just not wide enough (for me) for interior shots and landscape / travel photography / cityscape, etc.
I have an 11-16 Tokina and think it's one of the best UWA lenses every produced. I wouldn't mind owning a Canon 10-22 though, but love my Tok.
