Nikon has unveiled the 20.9-megapixel APS-C Z30, its smallest and lightest Z-series camera yet. Designed for vloggers and creators, it offers a flip-out display, 4K 30p video and a long 125-minute video record time when plugged in. The Z30 competes with Sony's ZV-E10 vlogging camera and has one advantage over its rival: It can shoot 4K at up to 30fps using the full width of the sensor.
