We had a maiden flight for DJI M300 RTK + Zenmuse P1 today (3/3/2021) at Martell Forest. Everything went smooth and successfully completed a 21-minute long autonomous flight mission.
Image quality from P1 was impressive. A picture paints a thousand words. Comparison of images from DJI Mavic Pro (12MP 1/2.3″ sensor) vs. Zenmuse P1 (45MP full frame sensor) at 120m altitude follows.
