Cosmicar Pentax 16mm f/1.4

[Alf]

I received it yesterday. Very well built, short focus distance, clean, vignettes terribly, love to play with it.

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:

That's quite a lot of vignetting indeed…

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...
