This is dependent upon the GSD (Ground Sample Distance) required by the flight.  If we take a flight @ 400 feet AGL (Above Ground Level), the following would be our capture area assuming and image is taken every two seconds with both cameras to the side of each other (a wider landscape or “mapping mode”): (A) 85mm on both cameras yield a GSD of 3mm and the sensor can image 6 acres in a single 22 minute flight (B) 55mm on both cameras yield a GSD of 5mm and the sensor can image 14 acres in a single 22 minute flight (C) 35mm on both cameras yield a GSD of 8mm and the sensor can image 39 acres in a single 22 minute flight.
