Based on real world testing, I would say 10 000 feet.

Hi: Last week was testing high altitude fly on Peruvian Andes. At 10,000 (3100 meters) at San Mateo, Peru, standard propellers behave erratically, high altitude propellers do a nice job. I also test the high-altitude propellers at 13500 feet, 5 to 8 m/s of wind speed without flying problems...

Thanks very much for the reply. That sounds great.

Excellent solution, thanks for sharing. I am using the DJI 12v car charger but the charger did not use the full charge of a standalone battery. Seems that the charger interprets that the battery supplies energy for a car and is getting too low to start, and cuts the energy. With the DJI car...

One critical issue for me was the limitation to carry I2 far from the car trunk for nature photography. The best spots are at a hiking distance. After several tries, I found the best solution is to adapt a real mountain backpack (I used a North Face 90 lts.), with a comfortable harness system...

Thank you for your valuable reply and congratulations for the aerial compositions on your blog. Jorge

Many thanks Michael, I appreciate very much your thoughts and experience. I was also considering a S900 for Alpha 7 but I found many reliability issues reported by the users, from harmonic vibration to constant replacement of motor supports. I take that X5S image quality should not be the same...

Thank you NickU for the reply. The gut test is a valuable non empirical criteria. If the mirror slap in a DSLR can deteriorate image sharpness, I supose that drone vibration could be a huge issue despite gimballs. I uderstand that a mirrorless camera doesn´t have mirrors.

Hello: I am a pro photographer exploring aerial photography. In the previous months I broke two Hubsan X4 getting used to the controls. Now I am flying confidently a P3P and it is time for the real imaging experience. There is a lot of information and samples to compare I1 vs. I2 for video...
