Query: You can't go wrong with this lens.

We just recently switched from Olympus to Canon and this lens was the first one we purchased. I have to honestly say that this wide open aperture (f2.8) makes a big difference. We rarely use flash even in dark rooms. This lens is quick, well build and IS is very useful. It's also very sharp. The 17-50mm range is not great but for portraits, around the house and landscape photography us enough. Our second lens is EF 70-200 f2.8 IS II USM and this one is our workhorse.I recommend this EF-S 17-555 lens - it will make your life easier in low light conditions and any other time.Don't forget: photography is all about to take your camera, go out there and have fun! With this lens you will have less to worry about when taking all these great photos!
