Canon EF 50mm f/1.8 II

Bryce: This is by far the best lens you can get for the money on the market. The image quality is fantastic when you look at the price. I almost feel bad complaining because this lens is such a good deal. Also, if you're using a camera with a cropped sensor (T2i, for example) you're going to have to back up quite a bit to fit everything in frame.

Seroga07: This lens is awesome for many reasons. First off its the cheapest one to rent! Second it performs just like the more expensive lenses that come from Canon's more expensive range, similar to the 50mm 1.4. The only difference is that the body is made of plastic, but being so cheap they're a lot easier to replace. Basically you get stellar portraits, low light shooting, etc... But for much cheaper. Just be careful with it and dont carry the camera by this lens.
