I’d like to talk about lenses right now. One lens that just about every photographer I know has in his kit is the Sigma 10mm-20mm wide angle zoom. There are two models: an F/4-5.6 and an F/3.5. The first is quite affordable and makes a great go-to lens for indoor shots with an APS-C type camera. I have one and love it.
People often ask me what kind of telephoto zoom they should get. Everyone seems to want to shoot things that are far away. I always tell them to start with a good wide-angle lens. Most people will take family and vacation shots and never seem to be able to squeeze everything in. This lens will do the trick.
There’s a great review of this lens at: http://www.dpreview.com/lensreviews/sigma_10-20_4-5p6_n15
