Blackmagic Design Focus Demand

About Blackmagic Design Focus Demand FEATURED REVIEWS See all 1 reviews   Great with limitations! By Brandon P. Works perfect! Know that it works with BM 4k studio or 6K cinema, but NOT the 4K CINEMA! I had to find out the hard way by ordering cameras they did not work with it and then talking to Black Magic. Get accurate focus control with Blackmagic Studio Cameras. Eliminates the need to reach for the lens because you can control the lens direct from the tripod handles, just like a true broadcast lens. Blackmagic Design Focus Demand Features Compatible with Studio Camera 4K Pro and 4K Plus
