Title: nice upgrade
Review: This is a great upgrade lens from any kit lens; the optical quality is quite good, and the IS helps. When using the IS, remember to keep the shutter half-way pushed for about a second before shooting, which allows the IS to kick in.On my 40D, I felt this lens was a bit tight due to the crop factor. I picked up a 5D (original version) and the lens came to life. I really like the combination and have decided to put off getting a 70-200L for a while. This will do just fine. I just have to decide what wide angle zoom to get, now (probably the 17-40L).My gripes with this lens are minimal; the lens does extend when it zooms; the rotating focus element is not a problem for me. Sometimes I forget to change the lens settings on the lens (mode 1 or 2, AF on or off). It's just something I have to learn.
Is the review positive or negative?
