Kit Lenses for Digital Rebel I've been told with other lenses, I have to take the focal length times 1.6 (I think) to determine what my lens sees. Now, if the kit lens was made specifically for the Rebel, is 18mm really 18mm or is it 18mm X 1.6? I know this is probably clear as mud, but that shows just how little I know. Thanks for any guidance.

The EF-S 18-55 is made specifically and exclusively for the Digital Rebel. Nevertheless, the same cropping factor applies. 18mm focal length is 18mm focal length, regardless of the camera format. But because the digital sensor is smaller than the 35mm film frame, the angle of view of 18mm on a Digital Rebel will be equivalent to 29mm (18 x 1.6) on a 35mm film camera.

Woody, kits typically include a lens that has a small max aperture and a pretty standard focal length like 28-90, because they are inexpensive to manufacture and are good "starter" lens. Anyway, because of the crop factor, Canon purposely uses a shorter focal length range (18-55), so the effective length becomes 28.8-88, which is quite close to an ideal standard of 28-90.

Thanks for the added info Steven. Explains the f/3.5. I certainly like that.
