Canon 17-55 Sharpness

I just got a Canon EF-S 17-55mm IS lens. My captures really didn't look very sharp when previewed in camera, but I think you will agree that they do look pretty sharp on a computer monitor.

 

I also took one of these at F2.8, but either I botched the focus or the camera did and the text wasn't in focus. I will probably post something at 2.8 tomorrow.

 

Its maximum magnification is less than the kit 18-55 IS II, I am eager to find out if that makes this lens difficult to use for food photography
