I concur. I used to use my 70-200 f/2.8 IS on a rebel XT.


There are some lens/body combos that IMO don't make sense because there is a better, cheaper option (eg, I think a 200mm f/2 on a 1.6 fovcf body would be a little silly, since a 300mm f/2.8 on a full frame body would be cheaper and better in most ways, or similar for a very wide lens on a 1.6 fovcf body). There are also some lens body combos that don't make sense because the ability of one far outstrips what the other can take advantage of.


I don't think the 70-200 f/2.8 IS falls into either category. True, most people willing to spend the money for the 70-200 f/2.8 IS will be willing to buy a more expensive camera than the rebel. But the rebel + 70-200 f/2.8 IS is by no means a silly combination.


I recall seeing a bunch of great bird pictures taken by some guy with a sigmonster (sigma 300-800 zoom, which costs like $8000) mounted on a rebel.
