Kowa LM6HC 1" 6mm F1.8 Manual Iris C-Mount Lens, 2-Megapixel Rated

I have been trying to use this lens on the Blackmagic Cinema Camera 2.5k, not the pocket camera, and I can't get anything FARTHER than 4 inches in focus at all. I can set the lens to F11, which is small as it goes, to give me the largest depth of focus, and everything more than 4-6 inches away is out of focus, when set to infinity. It'll focus on things almost touching the lens though.

Great

I can confirm that this also covers the original Blackmagic Cinema Camera 2.5k, not just the Pocket Blackmagic. There is some darkening and softening at the corners but it is certainly usable. The BMCC 2.5k isn't quite full-size MFT (2.39x crop instead of 2x)
