The other day I showed how you can use an Android Tablet to wirelessly connect, control, and display a Live View video feed from a Panasonic GH4. If you didn't catch that video, it's a very cool feature to have when shooting with the GH4 (found here).

Wireless Control and Live View for Panasonic GH4
If you're shopping for a tablet with an excellent display, plenty of horsepower, and most importantly connects to the Play Store to download the proper Panasonic Image App, there's a deal on the Samsung Galaxy Tab 3 7" version (refurbished) for just $119 (found here).

I find the 7" size is manageable without being oversized. If you're looking for a simple way to attach a tablet over your camera, i've been using this universal Square JellyFish clamp. Folds up small, very good build quality, and perfect for tablets 7" or under . It offers a tripod mount, and can be used Horizontally or Vertically (found here).

Post author@Abby Eagle - It's possible, but only to a certain distance and it will not stream in real time nor have the sharp image quality like the HDMI can provide.

Can you use the tablet as a field monitor for the GH4?

I'm still resisting the GH4, for no other reason that i need to reduce purchases. features like this are certainly not helping that effort! If they come out with additional power zoom m43 lenses, my wallet will be in trouble
