† The airliner you were travelling on would havecertainly had a few in the inertial navigation system. Most Aerial Photographycompanies have known the benefits of Gyro stabilisation for many years.However, with the advancement in stabilised lenses is there a benefitin using an externally mounted Gyro unit such the K8 or K9?

The advancement in Digital SLR's has allowed a greater range in theparameters of photography and with a touch of a button ISO settings canbe adjusted, shutter speed altered and the focal length selected. Thismakes it possible for a Photographer to maintain a high shutter speedwith a relatively high ISO setting and merely monitor the Focal lengthusing the Timer Value setting on the camera.

Most Aerial Photography isundertaken in good condition with little cloud cover and good sunlight.This alone will allow ISO values to be kept relatively low with a highshutter speed but the investment in high quality professional lenses isalso important. A lense which can operate down to an focal length of2.8 or even 1.2 gives the photographer much more flexibility whenselecting settings. It must also be remembered that most aerial photography is elevated landscape photography and therefore a low focal length can cause problems on large sites.

A gyro unit such as the K8 or K9 will provide stabilisation but theycan be large, heavy and awkward in the confined space of an aircraft.Providing the photographer is not resting arms and elbows on theairframe of the aircraft the vibrations can be minimised and should notcause a problem and shutter speeds around 800th/sec should also help.

It would appear therefore that the use of a gyro unit for Aerial Photographyis perhaps not necessary in most conditions. However, night shootingwhere much slower shutter speed are permitted would benefit from theuse of a gyro stabilisation unit.
