Hi all, My brother needs to buy a new video camera. They need to video their top fuel dragster. They want a high def camera. They have a $3500 budget. Because the motion is extremely fast, I suspect progressive scan. The race is under 5 seconds long. There is a lot of vibration, some cameras can't handle this, but their Sony does well on this point. They presently have a Sony HDRFX7. They are looking at a XHA1. Another idea is a camera that has high FPS, like 100 FPS or faster. Anyone with comments, recommendation etc?
