Well I own a 17-55 now... and it's a big improvement indeed! I get the detail I was looking for and I can take nice pictures in low light without a tripod (a very useful object that I hate to carry around, displace, fold... it's too slow). I get almost no errors on focus (I got one this evening out of 361 photos).


When I exchanged the lens on my 7D, I felt the ensemble was much heavier with the 17-55, and it obviously was all front weight. I tought my camera was unbalanced with this lens, but my sensation turned into high-quality-feeling (and good comfort) as soon as I began shooting. AF is really fast and quiet. On the other hand, the IS start and stop noise is noticeable and not very pleasant. The focal length range is good for my own general purpose use but not enough for everything I'd do, but I knew this already.


I'm going to use the 17-55 extensively in the next two weeks and I'll try to understand what I'm not getting from it, then I'll ask you again for a friendly advice.


Thank you for now


See you soon!
