This was Dallmeyer’s standard 1 inch (normal) lens for 16mm C-mount cameras. They also made the 1 inch f1.9 Super Six Anastigmat in a couple of C-mount versions, which is a very different lens, with much less distortion and larger image circle. This lens gets “Petzval-like” off center, and does not fully cover the APS-C frame, but it is sharp in the center and can be cropped to present a very decent (and interesting image). Without coating it has a hard time against the light, but is a very nice 1 inch C-mount lens for bokeh explorations.
