Bro, just checking but have you actually taken aerial photos before? Sure a gyro can ensure low shutter speeds and a stable platform but one can shoot handheld from a chopper as I have done many times in the past using 35mm and MF cameras. All depends on time of day and weather. Equipment wise, it depends on the type of shot and the altitude the chopper is allowed to hover. Here in Singapore there are strict limits to the flight path and altitude the pilot can fly, plus chopper time is expensive, so one has to work very fast. Typically I used 35mm, 50mm, 85mm and rarely a 105mm lenses on 35mm format. One person to shoot and another to load film and shoot with a backup camera. Zooms would rarely be used because: 1) the chopper is always moving and there isn't time to compose, so sequential shooting is a must, and we already know the rough angle of view of the prime lens we're using 2) light levels can be extremely bright since the chopper is usually flying in a large descending spiral over the subject, so lens flare is an issue, hence fast primes over zooms and no filters where possible. Flying in a chopper is very noisy, so everyone wears a headset to cut out the noise and to communicate with one another. There is noticeable vibration so shooting is usually at the highest shutter possible. The other issue is that it is easy to get airsick as even when hovering, there can be sudden gusts that will pitch the chopper up or down or sideways. No a nice experience for those with queasy tummys.
