I've been thinking about purchasing a new wide angle lens.


I currently own a 24-105L f4.0. I am used to the high quality images I get from this lens. I've tried other lenses such as the kit lens that came with my XTi 1.6 crop factor body, the EF75-300 non L and have been very disappointed with the quality of images. I don't want to go down that road again.


I need a wider angle than my 24-105L provides on certain shots. I was thinking about the 17-40L but I'm afraid that won't be wide enough either. With the 1.6 crop body of the XTi, my only other option is theCanon EF-S 10-22mm f/3.5-4.5.


Will I be disappointed with the image sharpness/quality compared to my 24-105L if I go with the EFS 10-22mm? Or, should I just sacrifice the wide angle and go with the EF 17-40mmL?
