How fast exactly?
Without more info, what I can say is that flash will be the biggest problem. Many cameras can shoot very quickly, up to 10 shots per second, but only without flash. Flash needs time to recharge. What kind of environment is it specifically? What is your budget?
I need a camera to take pictures fast, taking pictures one after another of different objects, maybe 15-30 quick pictures in a row in quick succesion. I don't need any zoom and I'll be in a dusty enviroment... so I think a zoom may attract dust and jam up.
Flash will be needed in each photo.
Thanks to everyone that can help with their input! I've seen a lot of great posts on this forum.
