DJI have really moved their Mavic model forward with the 2Pro.
Over and above the original Mavic Pro, the Mavic2Pro adds:
33% more flying time per battery
8 vision sensors (previously 2)
40% quieter start-up and flight noise (noticeably so)
1inch CMOS sensor (against the previous 1 2/3in)
10 bit HDR 4K recording (against the previous 8 bit - from 10m colours to 1 billion!)
Aperture control (recommend shooting wide open at f2.8 and using ND filters)
That's an upgrade worth paying for. It's a superb machine, highly portable and packed with great features. One of the very best drones on the market.
As they say, you get what you pay for. But this sturdy drone is guaranteed to put a big smile on your face and give you many years of flights and fun.
