I want to be able to shoot video footage in the best quality I can of vibrating grains on membranes (cymatics).
I'm wondering if I should I swap my Canon 5D for a 5DmkII, buy the cheaper 7D, buy a different dSLR with video capabilities, or buy a good camcorder instead?
I am concerned that a camcorder wouldn't be able to get close up video of the cymatic phenomenon...
