Bought my first DSLR, a Canon 60D with an 85mm f/1.8 prime to shoot my granddaughters gymnastics. I now know I need a telephoto or zoom lens and from what I have read on this site, the 200mm should get the job done. The price on the 200mm f/2.8 USM II prime is about half that of the 70-200mm f/2.8 USM (non IS) zoom. Will I regret getting the 200mm f/2.8 USM prime now, as opposed to the 70-200mm f/2.8 USM (non IS) zoom later? Most (90%) of my shots are from the bleachers and I have plenty of time to change lenses should I need my 85mm. From the bleachers the longest shot would be about 100 feet and the closest 30 feet. Is the zoom really worth the extra money?
