Cons: MF-switch, feels a bit loose when shaken, AF-problems, light falloff
Pros: Resolution, even at f/1.8 excellent results!, sturdy, not too big, resonable distortion
Summary: This is my most used lens. A good alternative for obsolete Nikkor AF28/1.4 or MF35/1.4, nice close-up focusing and good colors, not too prone to flare. Try to test one before buying, older copies tend to focus wrong on new bodies. Well balanced ergonomics when mounted on D300/D700/D3.
