I'm a teacher in a high school where some students have expressed interest in taking a video production class if it were offered. I've volunteered to teach it, and I'm trying to put together a list of equipment we'd need to get started. I'd like to teach using prosumer to professional gear. I'm thinking of either purchasing a Sony PXW-X70 or a Panasonic AG-AC130A. Which should I go with? What should I look for in a camera for teaching the fundamentals of videography?
