The HDVF-L770 7" LCD HD Viewfinder from Sony is a 1920 x 1080 color viewfinder designed for use in 4K live production. It is directly compatible with Sony HDC and HSC series cameras. The 1920 x 1080 LCD panel allows for more precise focusing, with a very high 1000:1 contrast ratio and a WFM (waveform monitor) function for precise exposure control.

The viewfinder has a large handle, a lifter, and a bezel, as well as a lift/tilt lock lever for adjusting friction. A 3G-SDI input connector adds flexibility for viewing camera or external sources, while six assignable switches on the handle allow for bespoke setups.
