This is a great and sharp lens, but the problem is, that once a year, you will have to take it to Nikon to get oil cleaned of the aperture lamellae. If you don't - the oil will cause drag, and stop down too slowly, and all photos (except the ones taken wide open of course) will be over exposed. The smaller the aperture you have chosen, the more the images will be over exposed.
This is a known error to this lens. Nikon i Denmark (sort of like Bangladesh) denies any knowledge about this issue.
Not worth buying for this reason.
