This is my standard zoom lens for my Canon T1i. It’s the basic lens that Canon gives you with all of their enter-level cameras. It’s a pretty decent lens that produces a sharp, clear picture. Out of all the lenses I own, I use this one the least. I don’t use it that often because it’s not versatile enough for what I do. Not that this is a bad thing, but I think its to wide for portraits and when I zoom in, the aperture closes down to f5.6 so it’s not very bright.
