Request: 300mm Samples with the Canon 70-300 IS

[jonnahalf80]

I am torn between buying a Canon 70-300 f4-5.6 IS and a Canon 70-200 f/4 L, which are both almost the same price. The former has better zoom, IS, and I don't think the 5.6 will be terribly annoying to me since I can compensate it with slower shutter - most of the time I won't need high shutter speeds in low light.

So, the biggest complaint I hear about the 70-300, besides the rotating focus elements, is the sharpness, specifically higher than the 200. I must say I have a Sigma 18-50 f/2.8 Macro DC and am not very happy with the sharpness over the entire zoom range, so image quality is to me a very important factor.

I hope any of you guys who have a Canon 70-300 IS could post some 100% crop 200mm+ samples. I have an XTi, but I guess the sharpness is more related to the lens than to the body!

Thaaaanks.
