I would like to use my Canon Rebel TI for wildlife photograpy, birds mainly. What lenses can be used on this camera, brand name specs etc for outdoor wildlife shooting. Thanks.
Obviously Canon EF lenses but there are a number of 3rd party mfrs., Sigma, Tamron, Tokina, that are high-quality. For bird photography you'll need a telephoto and it depends on the circumstances what focal length you'll need. Probably at least 300mm. Look at the Canon lenses labled "IS" for Image Stabilization.
