that's a nice shot, thanks for sharing. I find it quite more interesting than the regular lift-off shots.
btw, what are you photographing exactly from that platform that requires fast AF? whatever it is, 7D will sure do the job. you'll also be able to crop freely since it offers a lot more pixels than your current body.
Thanks, I've tried to UL a larger version to the galleries but ran into some trouble reducing the size of the image. My post-processing skills are even worse than my photographic ability...
I do a fair bit of aerial photography- both from Cessnas and from the jets I fly commercially. Even at the relatively low Cessna speeds shooting landscape- the Rebel's AF is taxed. But even worse are all the great shots of jets crossing paths that I've missed over the years because the relative speeds (TAS of 440-460 knots for each plane) just being too great.
Some of my colleagues who shoot air races and warbirds swear by the 7D but due to the lack of crossing-traffic type airliner shots on our pilot forums- I suspect that even it can't handle the latter scenario.
