Hi everyone !
As I modified my Yi 4K+ to accept C-mount lenses (and by the way, other mounts), I've tested on it the following lenses :

Wollensak raptar 6.5mm f/1.9
Wollensak raptar 6.5mm f/2.5
Wollensak raptar 1,1/2 f/2.8
Kodak cine ektanon 38mm f/2.8
JML 17mm f/0.95

All the D-mount footages are in a flat color profile.
There are some LUTs on the JML footages.

looks nice, can we see the setup.?
The problem with action cam and manual lenses, you cannot see it's focussed or not. How do you did it?

Thanks,

I'll post pictures of the setup soon.

For the focus, I monitored the screen with the phone application. It's hard to focus with wide lenses like the 6.5mm. I'm thinking about acquiring a tablet to make a better monitor.
I'm actually working on some LUTS for color correction; it's a bit difficult because it depends on each lens, each lighting scene, each desired mood... Well, I'm learning about the hard work of colorists.
