Some Directors may want to look over your shoulder to see what you're shooting, so by streaming a video feed over, they can stand aside while you shoot. This is a test of an 8" monitor that has built in wireless, powered by a Canon LP-E6 battery, and a remote is mounted to the camera. It also has an HDMI input for non-wireless. That's all I can say for now.
Ok, someone nailed it. It's an 8" HDMI LCD monitor, but has built in wireless and comes with an SD Video transmitter. Normally around $500 bucks, there could be a few dozen available (soon) for around $200-250 which is why I was testing it out to see if it could be useful in some ways. It doesn't appear pixelated even when using the 5D Mark III SD out port. I could see this being used to send video out to someone who needs to see it. What do you guys think, at a lower price is this something useful? Find more information about it below (click here).
