What to look for in a 4K video camera

Your guide to video camera specifications and accessories

Sensor size: 4K crossover camera sensor sizes include the familiar full-frame, APS-C and Micro Four Thirds. Some pro video cameras use Super 35mm – roughly the size of APS-C, but with a wider aspect ratio.

Crop factors: Not all cameras capture 4K video across the full width of the sensor, which can introduce a ‘crop factor’.

Autofocus: Most makers offer fast hybrid phase/contrast-detection on-sensor autofocus systems. Nikon DSLRs still use contrast autofocus in video mode. In reality, many videographers prefer manual focus.

Live view: Mirrorless cameras offer full-time live view both on the rear screen and in the viewfinder. DSLRs only offer rear-screen viewing.

Touchscreen control: Useful in videography because you’re less likely to jog the camera.

Tilting screen: Useful when filming at low angles or ground level.
