Absolutely incredible lens. One of the best Nikon has ever made. If you're looking for something that is fast and tack-sharp this is for you. However, watch the focal length. Just like any other lens, on digital it's a 1.5x crop, so this lens is really a 127.5mm. If that's the length you're looking for, get this lens. However, in my case I'm glad I rented it since it's not really a length I need as it overlaps my other lenses.
In short, if you want a 127.5mm 1.4 lens, this is the one to get!
