Kent,
I have tried a number of c mount lenses on a V1 using a cheap adapter. Most lenses didn't cover, or sometimes even illuminate, the cx
sensor. A couple did work OK, but weren't great. It was one way to try a fast f1.4 lens before Nikon came out with the 18.5mm. You
might be fine using interesting antiques to get a special look.
Another problem was that the c mount adapter has to recess the lenses a little bit into the body. Several lenses wouldn't screw all the
way in if the back or the lens barrel was too large. Opening up the recess a little bit on a lathe helped. The V1 only operates in manual
exposure mode with the adapter.
If you hold the c mount lens in front of the lens mount, the LCD on the camera will give you an idea of what the lens will do. Think of it as
a completely manual lens baby.
The adapters are cheap. Have fun experimenting.
