I currently have a Digital Canon EOS Rebel 300D with the kit lens that came with it, a Canon EFS 18 -55mm. I would like to add a telephoto zoom lens in the range of 70 or 75 to 300mm. My wish list says a Canon Zoom Telephoto EF 70-300mm f/4.5-5.6 DO IS Image Stabilizer USM Auto focus Lens would be just about perfect but, my wallet does not agree. Nor does my wife. So, I am currently looking at the following two lenses: Canon Zoom Telephoto EF 75-300mm f/4.0-5.6 III USM Auto focus Lens Tamron Zoom Telephoto AF 70-300mm f/4.0-5.6 LD Macro Auto focus Lens Any comments or suggestions would be most appreciated.
