We watched a falconry display today in the grounds of Lacock Abbey. I tried to get some shots of the amazing birds as they flew but they were so fast - especially this peregrine falcon - that it was very tricky to catch them in flight, even with my motor-drive taking continuous shots per second and a high shutter speed! It was the first time I've ever really wished for a long zoom lens, as well. My 70mm just didn't cut it. As a result I've had to crop this in really close, reducing the image quality significantly.
