7 out of 10 points and recommendedInexpensiveAuto Focus noisy and sluggish.
This is a full frame lens and I'm using it on a crop sensor body. I am very pleased with the image quality. Real life isn't tack sharp why should the images we capture be any different? The softness this lens reputedly suffers from is nothing that correctly used software can't sharpen and maybe it's just me but I like the realism the lens captures. One bugbear. Autofocus is incredibly noisy and annoying sluggish. This problem is easily eliminated by switching the lens to Manual and using it the old fashioned way.reviewed January 8th, 2013 (purchased for $159)
