I love this lens. It is very good for indoor photography , because the relatively wide angle it covers lets you take in what is happening in an enclosed space, and the speed lets you hand hold your camera without a flash. It autofocuses quickly, and is plenty sharp. Because it's wide angle, the depth of field at large F-stops isn't hideously narrow. Well worth the money.

If you can find this lens, it is probably the best "normal" fast lens you can find to use on your digital SLR. The 28mm focal length translates to 42mm in digital perspective, which is just about right for most shooting. The F stop of 1.8 lets you do something you couldn't with film - shoot indoors without a flash. The reason film didn't work is because the colors are always off. With digital, you can adjust the color balance to be perfect without light-reducing filters. Besides, with the variety of flourescents used today, the color on film never comes out right. However, when used on a film camera, you now have a FAST wide-angle lens that will stop action. Lenses like this will become rarer as manufacturers make "digital-only" lenses (see the Sigma 30mm F1.4 for example). An additional benefit is that this lens is not overly large. It needs 58mm filters (not 72 or 77 like a lot of slower zooms do), which are a lot less expensive. Don't confuse with the newer Sigma 28mm F1.8 Macro, which uses the larger filters (and therefore is a lot larger lens). If you do your shopping, you can pick this jewel up for less than 200 bucks.

This lens is a must. The photos are crisp and clear; the colors true. It is easy to hold because it is light and small. The 1.8 makes it extremely useful in lower light situations. But it is also stellar outside in bright light. Quick focus.
