Especially in somewhat low light condition you are looking to shoot in, the AF will "jump" initially, and then "fine-tune" with smaller jerky motor movements. In decent light the initial "jump" will get you dead on focus relatively quickly, but the smaller fine-tuning takes about 5 seconds (no exaggeration). And that feels like an etttteeeeeerrrrrrnnnnnnaaaaaatyyyyyyy, because you can't pull the shutter until it completes [] I usually just end up using my 70-200mm f/4L, and the "fishing rate" is dramatically lower. Plus you also sound like Robocop when it's fishing for focus. It's THAT loud []


But other than that, I absolutely love this little lens!!
