We fly with a slow ultralight aircraft, where there is no cockpit window between the lens and the subject. My customers benefit from the low operating costs compared to helicopters. For example, we can also fly (at a minimum safety altitude of 300m GND) over settlements and crowds of people, where photo drones are not allowed to be operated.
A sensitive, digital single-lens reflex camera (full format) with top-of-the-line optics enables sharp and detailed recordings.
