B Mount for Ursa Cine 12K

Hi guys,

Does anyone have info on these. I have an otherwise complete setup and would love to start using it with B Mount. I have one on order with B&H but it slipped from expected next week to backordered.

Thanks in advance!

I ordered on B&H too and it’s backordered. I’m holding off on ordering camera until I get the power supply and B Mount plate. After all I can’t use the camera if I can’t power it up.

Fingers crossed B&H gets some in stock soon. As well as a bunch of other accessories like the PL Mount, 15mm Shoulder Mount Baseplate, and more. Would love to have a fully rigged camera by next month.

Hi Tim,

I actually found this B mount shortly after posting this and ordered it from Pro AV. They had it in stock and it shipped for $30 US. I had missed that this had been suggested in another thread.

You can also pick up a 8 pin Lemo power adapter from Wooden Camera that works perfectly. You will probably want a male to female 8 pin Lemo extension because they only give you about 3 feet. It looks like that is the same with the stock unit.

They still have the PL that I ordered available at Sweetwater:
