Canon EF-S 17-55 2.8 IS teaser

I got my hands on it today. My first impression is that it's by far the sharpest zoom lens in this range. I know it has the reputation for being ultra sharp, that's why I brought the Canon EF 50 1.8 with me to the city centre (mostly architectural photos), but didn't compare it - I plan to in the next few days. I think they are comparable at 50 mm, we'll see if my assumption is correct by the end of next week when I'll post a complete review, with 100% crops across the focal and aperture (f2.8-f8) range as well as IS tests.


center 100% crop: 17 mm, IS off, shutter speed: short enough;), ISO 100

100% crop: 55mm, IS on (I forgot to turn it off), f2.8, 1/200, ISO 100
