The 1″ is the smallest of the Super Six family. I have two, both in C-mount for 16mm film use. One is coated and one is uncoated. In practice I see almost no difference between them. The uncoated lens does have slightly more light artifacts when pointed toward a bright light source, but overall flare is about the same. They are noteworthy for their wide coverage (they will basically cover the APS-C frame with very slight cutoff at long focal distances) and the lack of distortion at the edges of the image circle. Very nice little lenses, especially for MFT, but unfortunately quite pricey, as are all Super Sixes.
