I own and have shot with a KS-8. The limits of my shooting have been with a DSLR from a self-flown aircraft. The system is clearly better than a stabilized lens alone. Because, time on station is typically short and costly, when flying, a digital capture system is recommended - for efficiency. I also believe that a MF digital camera would give results equal to 4x5 and perhaps 8x10 when altitude is sufficiently high. A gyro-stabilizer is highly recommended when shooting without a tripod in a situation where the photographer is moving.
