Cherie Irwin is purchasing a new wide-angle lens for her Canon 30D and wants some advice. Cherie says:
"I’m thinking about purchasing a new wide angle lens, since I am experiencing some major distortions and focusing issues with mine after I dropped it on the ground. I took into my local camera shop, and they can’t determine what is wrong with it. Since I have the Canon 30D, I’d like to go ahead and purchase the Canon 10-22mm. It has great reviews, and I’m not certain that the 14mm Rectilinear would work well on a sensor with a 1.6x crop factor. I know, based on some of the Flickr posts, that some of the contributors work on a similar frame with a 14mm lens. But, many of my clients have complained about the long center plane and stretching that the rectilinear lens creates…my competitor uses one"
Here's what I told her:
To me the sigma 10-20mm is an ideal RE lens for the 30D since it would effectively be a 16-32mm almost identical to what I shoot with (16-35mm on a 1Ds) and the thing I love about it is I can use it for exteriors and interiors. I try to use the 16 end only in small bedrooms and bathrooms and stay between 20 and 24 in larger rooms. Using a 14mm rectilinear (22.4mm on a 30D) would reduce your flexibility a some but it is famous for not having any barrel distortion. I would go with the Sigma 10-20mm just because of the flexibility of a zoom.
Anyone out there using a 14mm on a cropped frame body? I know Scott Hargis uses a 14mm on a Canon 20D. Cherie would like hear your arguments for using either of these two lenses. Help Cherie decide what to do.
