Minimum focal distance?

[SpatialProf]

I'm hoping to do some very low altitude vertical photography (possibly below 20m AGL) and I believe the limiting factor will be the shortest distance (range) for the camera to remain in focus (i.e. the minimum focal distance). I believe this may be 8m (24ft), but can anyone confirm please? Many thanks!

Phantom 3 camera focus distance

I have ordered a P3, and want to use it mostly for still photography. While the camera is obviously capable of taking some really stunning photos, it's going to take some getting used to a camera with a fixed focal length, fixed focus distance, and a fixed aperture. The fixed (wide open)...

The P3 cameras have fixed focus lenses and cannot be focused. They yield acceptably sharp images at 6 feet or better. Acceptably sharp is a human perceptual judgement, and depends on the display conditions - what resolution does the display being used have, and how close to the display is the viewer. My evaluations were from 4K footage viewed on 55” Sony 4K calibrated tv about 6 feet from the screen.
