This is a bit of 100% non-graded footage shot with one of the NX70's I owned in 2011-2012. It shows some of the great things about the NX70, along with some of the bad. Shot on a tripod in 1080 60p, AF, Steady Shot off, F4, auto shutter, auto-iso. Mic is a Rode StereoVideo Mic, mounted on the cold shoe on top of the cam.
Of course, since my account is not Plus/Pro, the vid is only 720 30p on Vimeo.
Good: The Sony Exmor-R sensor exhibits surprisingly low rolling shutter artifacts. Have a look at the twirling batons. Colors are vivid. In well-lit situations, the AF is spot-on, zero hunting. Audio S/n is excellent. When not using the XLR pod, the mic input is a handy 3.5mm jack.
Bad: Poor edge IQ. A lot of the blurring at the edges and corners is due to the high amounts of CA and coma (coma not directly visible in daylight scenes). The poor edge IQ is stark when compared to the "lowly" Sony HDR-CX550V; which cost half as much, and had a different lens design.
