Return video display function with P-in-P function

In case of multi camera shooting, the return video signal is so important for each camera operator to see the program video or the picture of the partner camera.

The main video and the return video can be switched to show on the LCD display from the zoom demand controller inside of HDF viewfinder.
Or the resized return video picture can be overlapped onto the main video pictures as the P-in-P function.


Direct function keys

Some of other viewfinders have “function keys” on the front panel, which can be configured with variety of functions.
