Is the nikon d5 good for video?
I can't tell you how good the Nikon D5 is for video. Its D5 page covers the sensor, build and announcement year, but not its video features, so I won't guess.
Measured against what makes a good video camera, it's a mixed bet. It's a heavy pro sports body with no in-body stabilisation, so you'd rely on stabilised lenses, and weight matters if you hold the camera for long stretches. For a wide option on this camera, the Nikon AF-S 20mm f/1.8G ED is in its lens list.
The video guide sets out what to look for: a screen that flips to the front, a wide lens, a microphone input and light weight. Check the D5 against that list before you decide.
