Olympic Airshow—Kaman HH-43 Huskie starting and takeoff

I was testing out a Sony A77M2 body at this airshow. This video clip is straight out of the camera. The lens is a Minolta 70-200 f/2.8 SSM. It definitely needs some post processing, but I guess that’s normal. What’s weird is the little “buzzing“ vibration you see from time to time, like when I zoom in on the rotor masts. I’ll do some more experimenting before deciding whether or not I’ll keep the body. Check out my photos of the event at my photo website:
