Review on Canon EF-S 17-55mm f/2.8 IS USM Lens - Compatible with Canon DSLR Cameras (Lens Only) by Boyan Mitov ᠌

Only the EF-S mount distinguishes it from L-ki, otherwise I didn’t see the difference, although I already have an elderly carc (400D) Before buying, I tried tokina 17-55 / 2.8, and so the original is much better! Very satisfied =) I advise the stingy not to pay twice! Has some pros: - tenacious autofocus - DOF is present, despite the crop and the 2.8 point - everything is fine with the case, it dust, it works without noise, I think it depends on the operating conditions and the accuracy of the user Some cons: A little pricey, but 100% worth the money! in my opinion, this eye binds the user to the crop =) I'm now thinking about a new carc and I understand that I could buy 5D if I didn't have such good optics on the crop.
