It was a bit noisy over Blenheim today.
I had a bit of adjusting to the big Tamron for aircraft. It was ideal for this one, but for the prop driven aircraft, the lens is almost too fast. I had to stop down to F8 at ISO100 to get some prop movement, as otherwise the lens was giving way too high a shutter speed.
I actually didn't take that many photos as most of the aircraft I've seen before, and once I have a good image of a particular aircraft, I don't feel the need to keep photographing it repeatedly.
