C-mount glass

Anybody been playing with old-school cinema lenses and the AF100?
Just curious what your experience has been.

Depends a bit on the lens .. (super16 etc.). At least that's been my experience so far. Played around with
an old super16mm Zeiss Vario-Tividon lens today and it's massively fun .. lots of vignetting and spherical
plane variation (as you beyond the field the lens was designed to project upon).
You can have the center dead-in and the edges blurred. Playing with the zoom allows you
to compose vignettes and spherics to some degree.

It's very much a "specialty" look .. and something i would never consider as a "main" lens for
the AF100. But, the old glass is still beautiful in its own way.

I put the Lumix 7-14 in there as a "polar opposite" comparison.

Also, a lot of my C-mount lenses do not seat fully in my m4/3 adapter fully on the AF100 because of the glass in the mount. They work on the GH2 though since it has no glass in the mount. I'd guess the glass in the mount may be there because of the ND filter wheel.
 
I think you're right. If I did the math right, getting infinite focus on the AF100 is not going to happen because of the ND filter distance. That doesn't negate usage
of these lenses as "specialty" glass (IMHO). I'm looking forward to getting the dual-ring C-mount/MFT adapter I ordered. That's
going to allow a lot more shallow focus possibilities.

I received the Hawk Peng C-mount to MFT adapter and it's a big difference over the Fotodiox adapter. It's significantly
thinner and allows the c-mount lens to get considerably closer to the sensor. Not quite infinite focus, but much closer.
