The best non-L lens for Canon APS-C camera photographers.
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.
