Initially I thought it's an AIs lens until I check the serial number, luckily it's manufactured near the end of Non-AI version and there's multi-coating. It gives more contrast than the AF 35/2, it's also very sharp from wild open at center; corner sharpness is good from f2.8 (on D200). Like the 35/2, this lens produces great star effect at night with large aperture settings. This is really a good performer, too bad it's only a 28mm.
