Yes, Ted. Everything IS vibrating..... except your subject.
And even if your subject is IN the helicopter, different materials and mass
will vibrate at different frequencies.
A Herc, flying straight and level, is a different animal then a chopper.
Shutter speed and not letting you camera touch ANYTHING is the only think
that will save you in a chopper.
I shoot from Helicopters A LOT. In a wind buffeted hover over the north
Atlantic you are risking the picture with anything under 250/th of a sec.
125th CAN be done in smooth air, with a pilot with a steady hand... and a
bit of luck.
My standard set up is Leica M's, Fujichrome 100, 35 and 50mm lenses, and
250th at (f2.0 to f8.0) as required for the light.
Here is a typical helicopter shot http://www.straylight.ca/locke/hibernia.htm
....and this was a very calm day.
