6 out of 10 points and recommendedSharp, very low CA, light and smallHuge amount of light falloff at 18mm wide open
This lens performs great wide open at all zoom stops, except for a large amount of light falloff at 18mm when wide open. Stop it down to f/5.6 when at 18mm if you want to get rid of it.reviewed February 3rd, 2007 (purchased for $453)
I upgraded from the 18-55 II kit lens. Sharpness at the corners on that lens was horrible but on the 18-70 it's great.
Chromatic aberration really bothered me on cheap lenses and this one has none of that! Contrast is also great with very little flare.
I compared this one to the 18-135 AF-S and decided on this one for the slightly faster aperture and the reviews I'd read.
