NO COMPLAINTS - SUITS MY NEEDS 100%

Autofocus: As you might expect from an AF-S lens, focus performance is generally fast and direct. I did see just a little bit of a hitch in low light that I don't see with the more expensive AF-S lenses, but not enough to quantify.
Sharpness: As with most of the DX consumer zooms, the 18-105mm is sharp to very sharp in the center, even wide open. It has slightly better performance one stop down, but not enough to avoid maximum aperture. Also like most of the other DX consumer zooms, the corners are weakest at the widest and longest focal lengths and pretty good otherwise. The corners never get terrible, but they barely rise above what I'd call average at 18mm. By 24mm, I'd rate them very good. At 105mm the corners are noticeably soft, but still usable. Overall, the lens seems well matched to the performance of the D90 (and D300) sensor: it's fully capable of resolving to the sensor's ability in the central area. Corners are tough to assess on most lenses via test charts because of curvature of field, but in the shooting I've done with the lens, I'd say that, other than 18mm wide open, the lens reaches the very good range or better in practical use. Considering the price, this is very good bang for the buck.
