This is a film with my new C-mount Cosmicar 12.5mm 1:1.4, modified to fit on the C-mount to micro 4/3 adapter (see pictures below).
This lens is less sharp than the Lumix 14mm 2.8, but faster. It's vignetting a little, not a lot for this focale. It's not protubing so no problems with the GH2.
I've put a 40.5mm to 43mm step up ring to adapt a 25$ variable Polaroid ND filter (sorry the film credit is wrong)
But with this the vignetting is bigger, that's why I have to zoom and crop the image for this movie (from 100% to 130%).
I also bought a Cosmicar 6mm 1:1.2, wich seems to be sharper, I will use it with the GH2 crop function, it's being modified, I'm having it next week, tests soon.
