Is the nikon d610 good for video?
The site doesn't say how the Nikon D610 performs for video. Its page lists the sensor, mount and size but nothing about video modes, microphone input or a flip-out screen, so check the manufacturer's spec sheet before you buy. The D610 has no in-body stabilisation, so for smooth handheld footage you'll want a stabilised lens. The Nikon AF-S 16-35mm f/4G ED VR is a good fit for a wide, stabilised look.
For what to look for in any video camera, from a flip screen to audio, read the Video guide. Sound is the part people most often skimp on, so budget for a microphone from the start. You can see the Nikon D610 page for the full list of lenses that fit it.
