I was so Zhalu buy my relatively short (2 months) before the on the market since the 7D even a 50D, because I sure was not a need to video function. Like so many times when you a better informed and now I'm trying to find a workaround.
My spontaneous idea was to buy a battery-powered HDMI recorder. I could retrieve the signal and simply record. Does it work? What is the frame rate for HDMI output?
