Blackmagic Design Focus Demand
With the popular MFT lens mount, Blackmagic Studio Cameras are compatible with a wide range of affordable photographic lenses. Photographic lenses are incredible quality because they're designed for use in high resolution photography. Plus, the active lens mount lets you adjust the lens remotely.
To eliminate the need to reach around to adjust the lens focus, the optional focus demand lets you adjust the lens from the tripod handles just like a large studio camera. This means you avoid camera shake when adjusting the lens, so you can track shots and operate the camera without taking your hands off the tripod.
