The $1,500 viewfinder (which also works on the URSA Mini), is a first of its kind from Blackmagic, and it's likely going to be one of the more essential add-ons for the Mini. That camera has not started shipping in any significant numbers yet -- though when we talked with CEO Grant Petty this year at NAB it was clear that this roll-out was going to be very similar to their other cameras, where a handful are released at first and then a few months later you start to see them in greater numbers. I would expect there to be many more shipping by this fall.

The newest firmware from Blackmagic adds support for this viewfinder. In addition, there are a few other URSA updates in the 2.6 camera firmware:
