Summary: Great buy for the money. Very usable and performs like a more expensive lense. I would recommend this for those looking for a good multipurpose wide angle lense without the super heavy pricetag.
Summary: Great lens. My old one was stolen, unfortunately, and Canon discontinued it at the same time. The new one has Image Stabilizer, which I do not really need on 24mm lens. Plus, the price for the new one does not look reasonable.
I've been looking for the best prime for my crop sensor camera

Summary: And I believe this is it. With the 1.6x crop on my T3I this turns out to be about 38mm. It is perfect for general walk-around shooting or candids. I also really like canons 35mm lens but the fixed focal lengths on this one serves me better. Very lightweight lens and it does look a little cheaply made, but once again I don't plan on tossing it around like a football so it should hold up.
Summary: Start with the Pros: Cheap - I got mine used for $180, with signs of usage but still perfectly functional. Sharp - Even wide open at F2.8, this lens is very sharp. Portable - It's very light, it's a bit lighter than 50mm F1.4 I think. It's small, it fits in small camera bag with my 5D MKII. Cons: Loud Focus - It doesn't have USM. Poor Built - Comparing it to 50mm 1.4 (which costs about the same), it doesn't have as good built quality and it has an old design.
