All of my CF 18 shots are with a 1D4 & 100-400 L and I think they were all shot at 1/1000. I used that body & lens for just about all the flying EXCEPT the Snowbirds. I switched to a 28-300 L for the Snowbirds. I did take a few shots with the 1Ds2 & 28-300 L but I don't think many will be used in the albums I'll be doing. I shot the same combinations both days & must have well over 2000 images to go through. Saturdays weather was a challenge lighting wise but luckily I shot RAW & jpg so I should be able to pull a few nice images of the CF 18 in much higher humidity. It performed right after the heavy rain let up. I was positioned just about 25-30 feet from the western most corner of the spectator area both days so I had a good vantage point for the take offs. Never left that area during the alloted flying time so if it flew I shot it, but one plane did perform his routing in that downpour so I've only got 4 or 5 shots of him Sat.
