12 4K video with HDMI out
Nikon’s addition of 4K video to the D7500 is very timely – and it’s another feature made possible by the new sensor and EXPEED 5 processor combination. It shoots in the 16:9 UHD format at a resolution of 3,840 x 2,160 pixels and at a frame rate of 30, 25 or 24fps. It offers HDMI output to external recorders, which will please videographers, and it also offers both external mic and headphone sockets – so it will be possible to use higher-quality microphones, and to monitor the sound while recording. Like Nikon’s other 4K-enabled DSLRs, though, the D7500 applies a ‘crop factor’ during 4K video recording. 4K video uses a 3,840 x 2,160 pixel area in the centre of the sensor, which equates to a crop factor of 1.45x. This means that your wide-angle lenses will be nowhere near as wide as when shooting stills. This might not be a deal-breaker, but it’s certainly an inconvenience.
