What settings are you using on the camera? I know nothing about using drones (yet), but have been a working photographer for over 30 years. I do shoot action quite a bit and also use some pretty extreme lenses (600mm) and motion blur, both from subject movement and from camera shake is a very real issue. To minimize motion blur, I generally shoot using "aperture preferred" with wide open aperture, thus maximizing my shutter speed for the prevailing light. Since almost all the aerial photos I see on these forums are shot with wide angle lenses, depth of field isn't really a problem, so should be fine with wide open aperture. The shots you posted are very nice. Better exposure than many I see on these forums. What lens are you using? Can you give a more complete description of your platform. I am in the early stages and trying to determine what platform would be suitable for a NEX-7 with a Zeiss 24mm.
Thanks
