That shot was taken using a Canon 10D with a 24-70L lens. Most of my ground work tends to be with that combination. Shots in flight are usually taken with a 100-400L lens.
I tend to shoot in RAW mode but if the light is particularly good (and I am running out of space on my various cards) I will drop back to JPEG mode
Always tend to set the SS at 1/125 for in flight work and work around that for the best aperture/ISO combination.
