Tom has recently posted his test on the new Canon EF 70-300mm IS VS Canon EF 200mm on Canon EOS 350D. He commented:
“All 100% crops, only the tree bark was sharpened. I concluded that IS is amazing! I also concluded I need to check my prime for front focusing, although most of the problem with it is too slow shutter speeds with no IS.
The 70-300-IS appears to be a very nice lens – although noisy focus, and hunts a lot with the TC on it. If I find my prime is focusing correctly, it’s going to be sold!”
