Summary: Purchased this lens for use on both a Digital Rebel (EOS 300D) and a Rebel 2000 35mm (EOS 300). With the 1.6x multiplication factor on the 300D this lens has a focal length of 80mm rather than 50. But, this is a tremendous prime lens - It's fast f/1.8 allows for fast shutter speeds or low light action. While it tends to be sharper at f/3 and up, you can't purchase many lenses even at f/3 let along f1.8 for $70.
If you bought the kit lens with your EOS body, this is the second lens you should pick up - if you can find it! Third, take a look at a 28-105 or 28-135 to get a little longer range, then work from there. The 50mm will really work with you to focus on the subject not the equipment.

Enjoy!

Summary: I bought the lens to go along with my 300D. The fast lens is great for indoor or low light conditions. It is also great as a general purpose lens or even for portraits. Have shot a few hundred images using it and am very pleased. Retailing at under $80, this is a great addition to any Canon lens collection. A solid product and excellent value. Rated as 4 only because auto-focus mechanism isn't Canon's best, as is expected at this price, but works perfectly well. No problems whatsoever.

Summary: The Canon 50mm f1.8 lens II autofocus lens is one of the best values around. This inexpensive and lightweight standard lens can be used for available light photography and can capture wonderful candid shots. Although not a zoom but a fixed focal length lens, this issue is more than made up for its sharp images.
