XHG1 is the cheapest cam with genlock and TC in/out, I think. XLH1 and HD250 (and HD200?) have it. Then pretty much any 2/3" camera should have it too.
What I was hoping was that this camera could be used in a 3 or 4 multi cam shoot where each camera would have an ISO recording and there would be one switched master as well.
You could always use a clapper slate to synchronize each take. I know there are large switchers with TBC's or frame synchronizers on the inputs for timing non-genlocked sources. Does anyone know if there is a simple, small switcher with those features?
Also, it looks like the camera's best output is through component. So you would need a component switcher.
