First Time Zoom lens, December 16, 2001
I'd just got into SLR photography and the first few months with the 35-90 lens that came with the Canon Rebel 2000 were outstanding. I never realised there was SO much difference between a point-and-shoot and an SLR. After reading p on some of the books about photography, I reaslied an important point was getting the right framing and getting close to the subject. So I set out to look for a cost effective zoom lens that would give me that flexibility. I tried the cheeper rip off lens in the loal camera store and found their mechanisms stiff and slow focussing. I stuck my neck out for a canon make lens, and this one jumped out at me. It's perfect, the shot are crystal clear, the zoom is smooth and the autofocus is just as good as with the smaller lens. How do they make these lenses so cheap when competing lenses are more that twice the price? highly recommended for a novice like myself whodoesn't want to sped too much for telephoto zoom capability. I'm now looking for a canon 2x teleconverter to add to my range.
