And I can't understand, why I should buy a camera which I will never use.
On top of that you can get some intereresting filters for the
M3C (which of course are cheeper too), which you can't get with the
Mavic 3 Standard, like Polar Pros 3 to 6 Stop VND Filter for example.
Those variable ND-Filters or any other fixed filter with single ND-Values are senseless with the
Mavic 3 Standard, because you need different f-stop reductions with both lenses , if you want to match them in exposure without the need of landing, adjusting or swapping out the filter on the ground.
BTW, why should I want the RC Pro if there isn't any SDK to get Third-Party-Apps on it? I have the RC for convenience reasons, and when it gets serious, I fly with the standard remote and an iPad Pro.
Finally, like I said, different scenarios, different production needs, different gear.
