Sigma 10-20mm Zoom

If you shoot interiors alot and either have or are thinking about the new low-end Digital Single Lens Reflex cameras (Nikon D50 or Canon Digital Rebel XT) you should be thinking about how to make either of these cameras wide-angle enough for interiors. The Sigma 10-20mm zoom lens is designed to be used with DSLRs when shooting interiors. The 1.6 times crop factor of both the D50 and the Rebel XT make the kit lens they come with (18-35mm) into a 28-56mm lens... not ideal for interiors. However, with the Sigma 10-20mm zoom you have and effective 16-33mm zoom- just right for interiors. The Sigma 10-20 is priced at about $499. This may sound like alot but the only other choice is for the Canon only; it's is the Canon 10-22mm lens for almost twice the price.
