Summary: This lens is a great compact lens. If you wanted to travel as light as possible, this is a great choice. It is wide enough for scenic shots, and great for street and distorted people shots. I wish this version had an Ultrasonic motor, but for the price, I can live with the buzzy motor. It also gives you an extra stop of useable light. The sharpness is still good wide open, but stopped down to f5.6 it is great.
Summary: Great high speed lens to use when space doesn't allow me to go with my 50mm F1.8 which is my favorite low light lens. This 24mm is a little better build quality, but not as sharp as the 50mm. But you still can't go wrong.
Summary: This is a great prime lens for a camera that accepts FD mount lenses. 24mm works great for indoor and group photos as well as fun handheld self ports. ƒ2.8 is fast enough to take decent shots in lower light.
Summary: I selected the 24mm lens to fill the small gap between my 10-22mm and my 28-135 lenses and it's doing a good job for me. Used correctly it can take very good candid 'portraits of opportunity' in crowded situations indoors without dealing with the bulk of the 10-22. I'm sure that I'll find other uses for it as well. It's not a FTM focus lens, but it wasn't priced like one either. A solid addition to my growing collection.
Summary: I bought this lens to use for a lot of different types of wide angle shooting. Particularly for shoot basketball games from the backboard. The lens is great in the aspect that I can get a large area of what I need to be shot without having a fisheye. Drawbacks, its not a fisheye obviously. I have to make sure that the lens is the right distance to get everything into perspective. Other than that I lo0ve the lens.
Summary: I love this lens. Very sharp, fast focus and nice and light. I've never had any problems with it aside from in one location wishing it was it's faster sibling the 24L, but even then that may not have been enough either. I find it sharper then all the L zooms aside from the 70-200 f/4IS. But maybe my copy is just really great. It's mainly my landscape lens on my 30D.
Summary: Good buy for the money. Very sharp lens, the wide angle is not very prominent in a 1.6 cropped camera but there still a nice wide angle effect, you get more of the frame. I use this lens more now instead of the kit lens in my XSI.
