I would like to share my experience with Sony RX0 which is a fantastic camera for surveying.
SonyRX0 zero is a small size, a shockproof digital camera with 25 mm wide angle (equivalent to 35mm)
It is only 110 gram with battery. Quality, size, wight make it suitable for surveying applications on drones.
Sony RX0 has a manual mode to set all camera parameters manually to get sharp pictures
to get sharp quality pictures you should consider to set few parameters correctly:
Shutter speed: to remove blur from photo shutter speed should be set for higher value. 1200–1600 is recommended. Higher the shutter speed reduce image quality.
ISO: lower the ISO higher image quality. ISO between 150–300 is recommended.
Focus: Recommended to set the focus manually on the ground before the flight. Direct camera to an object which is far, and slightly increase the focus, you will see on camera screen that image sharpness changes by changing the value. Set the image sharpness at highest.
White balance: recommended to set to auto.
