First look at a very new product (unreleased) (Patented Pending) that I showcased a few days back. Leo said it looked like a Canon 60D on steroids. Camera mounted is the Canon 7D. This is a prototype version and as far as I know, a very original product idea. I can't really talk about specs outside of the 5.6" HDMI LCD that swivels. I'm not sure how much it will change in the production model. There's built in speakers for playback, an HDMI pass through, and powered by LP-E6. There's an LP-E6 shaped battery case adapter that looks like it uses AAA batteries. So far it's very convenient to just mount an LCD monitor to your camera like a battery grip, and have such a large monitor available. It sort of feels familiar like using a GH2, T3i, or 60D.
LCD Timer Battery grips aren't new, but there are some new ones showing up on the market for the Canon 7D, Canon 5D Mark II, and Canon 550D / T2i, and even newer Nikon DSLR's also. The LCD in the battery grip provides settings for (Intervalomter) Time Lapse functions. It's quite handy to have the Timer Remote feature already in the camera, for those spontaneous timelapse moments. There does appear to be some limitations to the internal timer functions, but if you're spontaneous, I doub't you'll want to spend a few hours with your camera in one spot. Here's some additional specs:
LCD screen (back ground light) with Date/ time/ stopwatch function.
Standard vertical shutter button with on/off switch on the grip and infrared remote sensor.
Built-in storage compartment for Canon 5D Mark II battery door and tripod mounting thread.
Holds one or two Li-Ion batteries, you don't need to take the grip off.
Functions as a timer remote and can be programmed to function as an interval met
Design for group, macro, long exposures, continuous, motion shooting, etc.
These battery grips sure do look a lot 'fancier' than the the standard grip, and contains all the basic features of the regular grips, but there still might some limitations to the internal Timelapse (Intervalometer) features. If you want to dish out a few more dollars though, you can have something that stands out from the regular grips. Check out the line of LCD battery grips with built in Time Lapse Remote Function.
