little fella dont do too bad getting aroundHa! ok you got me!
ill search,
What are they physical dimensions of a 1" sensor? I assume that's the diagonal measurement so it's not actually an inch on any side....
Besides that, a 1" sensor camera on a drone that is supposed to be small and portable is simply unrealistic.

This is a good point, though. It is logical that the MP2, when released will have an improved camera since the Platinum didn't have any imaging upgrades. But, it also makes sense that DJI would steer people do the Phantoms and larger when they want the best sensors. Maybe they focus on lens upgrades, possibly aperture adjustments, higher frame rates, improved color accuracy, improved low light performance, etc. There is a lot they can do before going to a 1" sensor.
IIRC, the camera of the Phantom 4 Pro uses a 1" sensor and has adjustable aperture (f/2.8 - f/11). Based upon a quick look-up of sensors and diffraction limit, I'm guessing the best P4P IQ may be around f/5.6. However, it would be nice to not have to depend on ND filters to set SS at 2X FPS.They will not have adjustable aperture for a sensor this size. It is near the diffraction limit already.
Yes it would be nice. Some small cameras have internal ND filters to avoid the diffraction limit of the small sensors.IIRC, the camera of the Phantom 4 Pro uses a 1" sensor and has adjustable aperture (f/2.8 - f/11).

It shows the limit already at f/4, only one stop down from wide open.

I can't imagine that they would put a 1"sensor in the Mavic at this time as it would cut into their sales of the P4P. There are several sensor sizes in between 1/2.3 and 1" which might make sense.Yes, on a 1/2/3" sensor at 12 MP. However, the P4P camera and its 1" sensor is actually 20 MP. For this case (1" CMOS, 20 MP), the calculator shows:

So, on a 1" CMOS at 20 MP, f/4 isn't diffraction limited. Now, based on the same sensor (P4P), f/5.6 IS diffraction limited but only by 22% of the AD:

Furthermore, with the P4P's ability to choose aperture based on 1/3 stops, you will probably not exceed the COC at f/4.6, f/4.9 and maybe even f/5.0. That's a whole lot more useable (sharp) f-stops that the Mavic 1! Unfortunately, it means ND filters will still be needed and an investment required in new diameter filters!
IMHO, it would seem plausible that DJI wouldn't reinvent gimbal and camera technology but, instead, adapt already proven components to the Mavic 2. Any bets on the P4P camera being adapted to the Mavic 2?
Of course, we're all "shooting in the dark."
DJI is all about maximizing profit. They only make incremental changes to an existing product. Look how many folks rushed out to buy the Platinum and white Mavics, LOL. They will always leave you wanting more so they have something else to sell you.
That's very informative. Thanks!...
A 1" sensor has a diagonal of 16 mm. The 1" measurement comes from the outside diameter of the glass tube used on vidicon sensors (1950's technology.)
They will not have adjustable aperture for a sensor this size. It is near the diffraction limit already. Better low light performance will require a larger sensor unless there is some newly invented technology.
More than that:The new Autel EVO will have a camera with a 1" sensor AND an adjustable aperture on their $1299 model. Don't you think DJI will need to compete with their Mavic Pro II?

Autel is a Chinese company. It’s too bad that there isn’t a US-made prosumer drone.If they can deliver it,I would rather buy a made in USA drone.
