But the photography point still stands; the primary purpose for a large sensor and aperture is 3:
1. Gather more light to improve signal to noise.
2. Allow for aperture control to control depth of field.
3. To (maybe) improve resolution by allowing for more pixels without making them so small they trash the SNR.
In plenty of light with a subject that doesn't need DOF control, small sensors can work great and good ones can produce results as good as a medium format sensor. Really. You see this all the time where numerous dumb magazine articles show the latest iPhone producing results as good as the latest $5k ILC. It's not fake; it's DOF control not required and lots of light.
As a photographer *would* say, it's all about light.
OTOH, if you need zoom control for framing a subject, low light performance, fast shutter speeds to capture action, super wide angles, close macro shots, fast shutter response, sophisticated AF, real DOF control, etc. you need an ILC. But what are you taking pictures of with a drone that would need any of that? (I do value improved low light performance.)
Pilot institute does a nice job reviewing drone cameras
Air 3 vs
Air 2 vs
Mini 3 Pro vs
Mavic 3:
What does that video tell you? At or above ISO1600 (meaning low light) the m43 from the
Mavic 3 wins; to get the sharpness and excellent SNR the
Mavic 3 has to be stopped down to f5.6 i.e. the performance has little to do with the sensor and is limited by the *lens* and at f5.6 the Hasselblad is better than the others; the
Air 3 and the
Mini 3 Pro are basically identical; and the differences are really, really minor for how most people will use a drone including that sometimes the
Mini 3 Pro is actually sharpest.
OTOH, in case you thought sensors don't matter, check out the clear improvement from
Mini 2 to
Mini 3 Pro:
Good luck!
