The 28-105mm is a good replace on a full frame... to match the 18-55mm kit lens on a cropped sensor. Very happy with the results.

...The Canon EF 28-105mm f/3.5-4.5 II USM Lens is very similar to the Canon EF f/24-85mm f/3.5-4.5 USM Lens in build quality. The 28-105 II offers 20mm more zoom range on the telephoto end and sacrifices 4mm on the wide end. Of course, you might want to avoid that 20mm on this lens anyway. Use the mouseover lens comparison tool to see how these two lenses vary in image quality as the differences are easier seen than described. The Canon EF 28-105mm f/3.5-4.5 II USM Lens has a very nice focal length range that includes the normal, general purpose zoom range. Be sure to also consider one of the lenses suggested on the Canon General Purpose Lens Recommendations page before finalizing your 28-105 II purchase decision.
