If your project requires a lot of handheld or hand-held shooting, you'll appreciate the Blackmagic URSA Viewfinder.
A high-resolution 1920 x 1080 color screen gives you optimum focus. What's more, the screen is so sharp that it's impossible to distinguish pixels, like on the optical viewfinder of a traditional digital camera.
The viewfinder can be adjusted for left- or right-eye use. Just plug it into the power socket and SDI output, and start shooting! It incorporates a sensor that turns the screen off when you're not using it, so as not to waste energy and prolong the life of the OLED screen.
