Summary: The key reason that I bought this lens instead of the higher quality one of similar range with metal casing is because I'm a traveler. When I'm traveling, my Canon Rebel XTi and between one and three lenses go EVERYWHERE with me.
Summary: I had to replace my original Canon lens on my EOS T3i which was only a year old. That was a bummer, as the previous lens, (same one) decided to stop auto-focusing just after the 1 year Canon warranty was up.
Summary: This lens is fine; it is a basic "stock" lens. It works well for taking portraits and close up shots. However, this seller is lacking. The lens came to me with auto focus not working. This is not a huge deal as the camera does manual focus, but auto focus is a nice feature.
Summary: Purchased this lens as a wider option to the 28-135, knowing it was inferior glass compared to the Ultra Sonic or L Series line. But for the money it is a great option for stills because the image stabilization and auto focus are solid.
Summary: Its a cheap lens so you can't expect much. I shoot with a rebel t4i and replaced this lens with the sigma 17-70 f/2.8-4 because f/3.5-5.6 is just to slow. I always have to turn up my I so so I can speed up my shutter and that causes noise.
Summary: Okay. This is the the kit lens that comes with most canon DSLRs. The XSi, 40d and XS already have this. If you didn't buy the camera with this, I'd still suggest you move along. The lens is better than the older version that came with the Rebel XT or XTi, however it suffers from most of the same...
Summary: I passed on purchasing several identical lenses in stores due the excessive looseness of the lens tube in the barrel. The one I have is reasoably tight and is giving good service in general and with the close up lens set I purchased with it.
