I went to the Tucson Jet Rally 2007 today and found what might be the most difficult action shots ever. You need long lenses (my EOS 1DmkII hates the Tamron 2x Tele-Converter so I had to manual focus all day) and fast reflexes. I got some good action shots but mostly just take offs and one botched landing. My favorite part was getting to see all the planes up close. Here is my favorite shot from the day: This is as it came from the camera, not sure of the jpg settings but most likely default or close. I set the camera on the ground and 'hoped' I aimed it correctly.
