Be mindful of lens mount contacts

[rawCAM35]

Double check it to be sure that it is not your lenses, for example I checked my old manual Nikon lenses and I found out that some of the metal parts on the back of the lens comes very close to the chip contacts.
Non of my passive Nikon to EOS mount adapters have anything sticks out close to the chip contacts.

Chop the chips !

what kind of adapters did you use? makes me worried.

I've got lots but the ones with af confirm have to go. The BMC doesn't use it so get adapters without or take them off!

Electropolis also offers a wide range of spy products like the spy camera for recording or photographing.

Looks like I’m a little late to this party…

I too, shaved the pogo pins off of my BMCC EF mount using a cheap Nikon adapter. (Note that the adapter had no chip.)

I bought an EF mount for the Ursa Mini Pro and used the pins to fix the camera. It works fine now.

Tinker at your own risk, but you’ll need metric allen wrenches and a very small phillips head screwdriver.

I just thought I'd throw my experience in here, somehow I managed not to see this sticky before I posted - oops. I bought a UM4k secondhand off eBay from someone who said they strictly used manual lenses. I somehow missed seeing it in the images. Blackmagic reps also got back to me saying that it wouldn't hardly cost anything to repair ($100 - which is relative). I'll post an update once I send my camera out and back for repairs!
