Nikon D4 Video Demo from Dan Chung
We tried the camera’s clean HDMI output with the Zacuto EVF and Atomos Ninja and I can confirm that it works. We also tried the headphone output and the audio functions of the camera and I’m pleased to report they also work as expected.
Dan has included a lot more information on his blog – so please give it a visit: DSLR News Shooter | Nikon’s James Banfield demonstrates the video functions of the D4.
