Buying a second hand BMCC 2.5K

Here's a simple question.

There's a guy selling his old BMCC 2.5K MFT camera and he's asking €400 for it. Does the camera come with a licence to Resolve Studio 16?

No, it came with a Resolve dongle, and not sure if they are transferable anymore. You need to check and see if the seller has or registered his dongle, and it is included with the camera, and check with BMD support if the dongle license can be transferred. If I remember correctly, there was an issue with counterfeit dongles that led to the BMD policy change.
Cheers
