Motorised pan-tilt heads typically come in two flavours. They’re either fairly small and compact with a somewhat limited feature set, or they’re ridiculously huge, designed for broadcast cameras, costing tens of thousands of dollars.
Nikon subsidiary, the UK-based MRMC, is looking to bridge that gap. The MRMC SR-1 is a small robotic head providing pan and tilt control in a pretty compact form factor. You can even add roll control and focus motors.
