Are there any video cameras under $3000 that record to two memory cards at the same time? Right now I use handycam style cameras for my business since all my content is unscripted reality style stuff hence I need good follow focus, auto focus, auto exposure, etc, mostly heavy auto support since the scenes can change rapidly and unpredictably. My main fear right now is that each shoot is recorded only to internal camera memory, and I'm worried that one of these days it will fail and poof an entire shoot is lost. Are there any video cameras that record to two memory cards at the same time for some redundancy? So at least if one memory breaks I can still recover the shoot from the other. The Sony CX550 that I currently use has both internal memory and supports ad in memory cards but alas it can only record to one at the same time.
