I'm curious to see how the HDMI output works. I will primarily buy a camera like this to use as a low-lux webcam. The best one I've seen so far is the Canon 5D series; but those are super expensive and offer a pretty low framerate for video output.
If this camera can offer 30fps at 1080p through the video output, and give an option to hide the HUD, then its a BUY for me... I have tried doing all this with digital camcorders, but they just don't offer the image quality I expect from $500 cameras. They are marginally better than $50 webcams and don't work well in low-lux.
