Review on Canon EF-S 17-55mm f/2.8 IS USM Lens - Compatible with Canon DSLR Cameras (Lens Only) by Guanyin Lin ᠌
I was surprised by the quality for this price.
I was looking for a universal crop zoom. At first I looked at the Sigma 17-50 f2.8. But after testing it for a week, I was disappointed, because. There were big problems with the autofocus. I decided not to compromise and buy the original device. Expectedly better autofocus performance than Sigma, comparable in sharpness (both lenses are good). I don't regret the purchase at all.
Pros
- Constructive - nothing backlash, zooming is smooth. Constant aperture, and aperture 2.8 is absolutely working. Universal focal lengths. The stabilizer helps out when shooting handheld up to 1 / 20 sec.
Cons
- There is no hood in the kit, the stabilizer is a bit noisy.
