I bought a used Canon S70 digital camera a few days ago which will become my dedicated wingtip mounted camera. The camera has an Intervalometer that allows the camera to take a picture every minute until the battery dies or the memory card fills up (1 Gig Card). This makes picture taking hassle free since you just start it before the flight and don't think about it again. The camera is 7 Megapixels, and has a 28mm lens so I should be able to get everything in the shot that I want. The camera does a good job at taking long-exposure night shots as well, somthing I have not done since my camera I had in germany broke.
