Let me preface this by saying the autofocus didnt work right on my lens and I ended up returning it, so that may affect my impressions of the product. When manually focusing this lens, the image quality is pretty good. The manual focus ring is absurdly sensitive, however, and irritatingly goes beyond infinity. This fiddly focus is exacerbated by the lens creep. If pointed more than a few degrees up or down, the focal length will shift, meaning that perfect manual focus is now useless. The auto focus motor is extremely slow and loud (see above disclaimer) and will often have to focus up to infinity, back down to "0" then up to the proper focus (or close to it in my case). While this does have a macro switch on it that allows you to focus closer, it really isnt close. The minimum focus distance on this lens is 0.9 meters in macro mode, which is only 0.2 meters closer than the Nikkor equivalent without macro. That being said, you can still get pretty close looking images from 3 feet away. It just wasnt what I expected when I purchased a macro lens. That may be a demerit on me rather than the lens, though.
