I bought this lens in October of 2013 for my T2i and I love it. It's the only lens I have for my camera but I think it's worth the upgrade from the kit lens that comes with the T2i. Great all-round general purpose lens.

This lens is the same as the kit lenses that come with the rebel series. ONLY A LOT BETTER! first off the F/2.8 is great in all situations especially for wonderful bokah and low light situations. The only reason why this lens is not an L series is because it does not work with all the cameras.

Consistent Output; Easily Interchangeable; Fast; Rugged; Sharp Focus

Amazing image stabilisation that didnt work on a 550D but worked PERFECTLY on a 7D - easily best lens for EF-S - don't hesitate, just get one! Slightly too heavy, but will have to get used with it...

Scratches Easily

The 17-55mm is on my camera 90% of the time. I love this lens! I highly recommend this to every Canon crop sensor camera owner from entry level to semi-Pro (EOS 7D) who are after image quality. This lens can produce the output quality of an L lens (i.e.

- Fast and bright f/2.8 aperture with IS and USM; No other lens in the Canon EFS Line up can match this (so far) - Sharp pictures wide open from edge to edge (best @ f/5.6 up to f/11 if focusing is done correctly).

- Not weather sealed - Can be susceptible to dust accumulation in front element (if reviews in the net are to be believed); I don't put UV filters on my lenses, but for this lens I didn't want to risk the lens collecting dust, a filter will complete the dust sealing.

I have always been a canon user but have never been satisfied with the system when it went digital. My ef lenses never worked quite right and the ef-s lenses left a lot to be desired. This ef-s lens makes a great difference. It is well made, fast and gives crystal clear images.

Easily Interchangeable; Fast / accurate auto-focus; Strong Construction

Heavy

If Some One wants to shoot portraits or landscape from not much distance on a APS-C size sensor camera ,i would say you can't have better lens than this.

Consistent Output; Durable; Nice Bokeh
