I owned the P1, P2, P3Pro and P4Pro I am still using it. Next January will be its 5th birthday. It's time to upgrade.
M3 RC does not have HDMI unless you buy the priced Smart RC. I have the extended module with HDMI that allows others see what I am seeing in my device.
Mechanical shutter has been discontinued.
I understand improvements in sensing, flight time, sensor size and others that M3 Standard has.
With the Mavic series a problem with the Phantom series has been fixed: flare bands because of the sun and the propellers when filming. Time to time this has been an annoyed issue.
For about 2 years I was thinking the new Mavic pro would have an optical zoom, at leas something modest like 24-48mm, but OPTICAL.
You have now the same focal distance lens 24mm and another one 160mm (it is remarkable how the gimbal works fine at that focal distance and longer with its digital zoom.
Most of reviews acclaiming the zoom. Who needs those DIGITAL steps? Well people streaming while filming, search and rescue, see far details to evaluate if it worth fly to that point.
The rest is possible in post-production. Even worse using digital zoom, you cannot zoom out in post.
50mm lens/20MP/full sensor? Not possible. 90mm lens/20MP/full sensor? Not possible. It doesn't make sense.
P4P and
M2 have 3:2 ratio sensor size, M3 has a ratio 4:3. Keeping a 3:2 sensor ratio (wider sensor) videos would have higher size than 5.1
Cropping a 20MP 4:3 to 3:2 results in a 18.5MP.
My thougts.
