Customer reviews

From the first shots I took with this lens I was amazed by the sharpness. To my eye it looked much better than my 28-135 lens — when it’s in focus, it’s great. But the focus is the problem, for my copy at least, on a 40D, the autofocus was all over the map. In normal shooting I was noticing that the focus was way off way too often, my subject would be out of focus or just barely in focus, and the ground close to me or stuff in the background would be perfectly sharp. So I did some controlled tests and found that even in ideal conditions it was missing the correct focus on more than 1 in 3 shots. As in focus bad enough that the correct focus point was just on the edge of or outside the in focus DoF more than 1/3rd of the time. It looked like there was a tendency to front focus at the 50 end (which was what I was noticing in real world shooting) and back focus at the 17 end (which was just making landscapes soft), but overall I’d say it just tended to be really inconsistent, missing in either direction from one shot to the next. I also had a lot of exposure problems with this lens, but it’s the widest lens I’ve shot with so I don’t know if that’s the lens or the camera.
