The South African Aerobatic Championships is currently on in Phalaborwa
with plenty of Photographic opportunities. I've tried everything but
just don't seem to be able to focus on fast moving aircraft at height. I
get close with MF but AF.S AF.C are hopeless. Perhaps someone can
enlighten me? Perhaps screw drive is too slow? I've tried the K5 with
the HD 55-300 @ 300mm & the Sigma 170-500 DG @ 500mm. I can focus just
fine on the quarter moon!
The Airfield is less than 1Km from my house! About 40 planes are taking
part. The last event like this in Phalaborwa was about 25years ago so
this is quite something. Of course there are several wet blankets
complaining about the noise.
