I received it yesterday. Very well built, short focus distance, clean, vignettes terribly, love to play with it. Cosmicar Pentax 16mm f/1.4 Focal length: 16 mm Shutter speed: 1/100 sec Aperture: F1.4 ISO: 250
That looks like a full 4/3 frame shot to me… It's pretty hard to find a wide c-mount (assuming that this is a c-mount), but I just like the look of the sharp center/soft and dark corners. Especially for portraits. And a nice picture also
The lens is C-mount as you said. It really vignettes badly, but it has something. This is the original jpeg out of camera:
I would leave it as is. In fact, you should do a series like that... You may be surprised what you could do with that. With the right processing, the images could be very dreamy... Check out Emmet Gowin's early work.... http://www.masters-of-photography.com/G/gowin/gowin.html
the vignette is quite heavy but not as bad as my Cosmicar 8mm f1.5 here's my Cosmicar 8.5mm f1.5 for comparison (2/3" CCD format Lens)
