I think it's difficult to lump multiple purposes into one drone. For most real estate
photo work, the 12MP camera in the Mavic Pro will give excellent results for MLS listings. For real estate print advertising, the 20MP camera in a
P4P or
MP2 will give better outcomes. The Mavic Pro is noticeably inferior to the
P4P or
MP2 for
video work because of the internal signal processing as well as the camera resolution and sensor size. The rolling shutter in the MP or
MP2 won't be anywhere near as satisfactory as the mechanical shutter in
P4P for mapping regardless of sensor size. The
I2 may be the superior rig for mapping, but the size, price, and strong performance of the
P4P in mapping make it hard to choose the Inspire. And for photo or video inside a house, don't use a drone.
My recommendations are:
Real estate MLS aerial photos -- Mavic Pro
Real estate video and print --
P4P or
MP2
Mapping --
P4P
Best choice for a do-it-all is
P4P in my opinion.
Aside from all that, as stated in earlier posts -- the drone selection won't be as important as your eye for composition, your knowledge of how to use your equipment, and your skills at post processing. If you're just getting started, there's a bunch to learn. And I'd defer taking on video work until your photo work is no longer challenging.
