If you're shooting video with the Panasonic GH3, I highly advise you take a look at the Fhugen GH3 Video Cage. It's compact enough that you can leave your camera in there the entire time, and will give you more mounting points for adding on those necessary accessories. One question that comes up often is 'How do you add rails to the Fhugen Cage?'.
Although there isn't a dedicated 15mm rod adapter for the cage, the design is straight forward much like the tripod mount under your camera. You can mount it to a variety of baseplates that support 15mm rails (and yes it will be optically centered).
In the example above i'm using the PNCGear MP-2 dual rod baseplate (found here). There are height adjustments on the MP-2 if you need to make your rails slightly higher or lower. The baseplate can be used in any direction, but here I have the logo on the side of the LCD screen. Under the baseplate is enough tripod mounts to add your quick release plate of choice for tripod mounting.
Of course we're just using a consumer grade Rokinon Cine Lens, and an old $50 dollar lens from eBay. There's no doubt this adapter won't match up to the quality of the Metabones products. Anyone using serious glass worth thousands of dollars might as well pony up the extra cash for the Metabones MFT M43 Speedbooster (found here).

If you're a casual video shooter looking to get a wider field of view and increased light through your common glass, I think you'll be happy with the Lens Turbo. I'll probably go out and take a bunch of high resolution still images on the next outing, but for now let's hear a few comments about these first video test results. What did you guys think so far? [Comment]
I've had this Mitakon Lens Turbo MFT Adapter for a almost a week and I am just getting ready to publish a video showing some examples from this. Recently I noticed an increase of questions and the amount 'buzz' picking up around the Internet, so I wanted to quickly provide some additional important information. THIS ADAPTER WILL NOT WORK ON THE #BMPCC BlackMagic Pocket Cinema Camera. It simply will not fit or attach to the camera.
If you're not familiar with this adapter, it's similar to the Metabones Speed Booster (found here) (but less than half the price). Always a concern on smaller MFT cameras is the cropped sensor. The Lens Turbo adapter offers a wider field of view on these smaller sensor cameras and also increases your Aperture by 1 F-Stop. Your lenses are now wider and faster!
Right now the Lens Turbo MFT / M43 adapter fits Nikon (F, G, Ai, Ai-s, E) manual lenses and should work perfectly on your Panasonic GH3 or BlackMagic Cinema Camera MFT mount (not Pocket Cinema). How well does it actually perform? Give me a few days, and you'll see a video with a variety of examples.
Right now there is a Sigma Lens deal which includes the 19mm F/2.8 and 30mm F/2.8 prime lenses bundled into one discount price. You can choose either a set for Sony E Mount cameras, or the set for Micro Four Thirds cameras. I have the 30mm on my Sony NEX7 and really enjoy this lens. I may have to get a set for the new GH3 at these prices.
[Update] These sold out quick and the listing shows a Back-ordered status, but I have just verified with B&H you can still place an order if you want to take advantage of these prices and it will ship when it is back in stock. Click through the links below for the deal.
If you're trying to prevent glare on the screen, you could use an LCD viewfinder. Of course it makes it harder to see the screen from certain angles without having your eye placed directly into the Loupe. In these situations, maybe a simple sunshade or LCD hood would be a better choice.
I've seen the folding plastic pop up sunshades for mini LCD screens, but I haven't seen anything quite like these Vello Mini LCD Hood Sunshades. Looks like it just folds over the flip out LCD on your camcorder or DSLR (with swivel screen) such as the Canon 60D, T3i, GH2, or even the new T4i. Available in 2.7", 3.0", and 3.5" inch LCD screens via B&H (Click Here).

Here's a (fairly lengthy) look at the Gini Rigs GH2 cage that provides all the cut outs to view controls and still have access to different ports around the camera. It looks like it's cut out to allow the LCD to still swing out also. No doubt it's high quality stuff, but there's been mixed complaints about the threading used on these cages as they may not be 1/4x20 accessible, but looking through the top area of the cage there seems to be different sized holes and threads. Maybe the new cages are supporting 1/4x20?
Still waiting to hear back from YouTube member feha1000 about that question, or if anyone else can chime in about a recent Gini Cage purchase. [Update] Here's the reply:
About 20 1/4" threads are on the top plate only the res M5 threads , and yes they work well with friction arms
Anyone check out the Gini DSLR Cages for Panasonic GH1 and GH2 cameras? Snug fit, looks nice, but crazy expensive. [Thanks Habez] Gini's DSLR Video cages were recently criticized about the lack of 1/4x20 threaded ports which is most common for adding accessories, and ends up using a different thread pitch. People have had to drill and tap the holes themselves in order to be usable. From the deign, this one doesn't appear to be any different. Maybe i'm wrong about the thread size. Comes with two handles, two monitor arms, and cage. (click here for Gini DSLR cages for GH1 and GH2 cameras).
Ray writes in and shares an interesting link to some very cheap Panasonic 14mm Lenses. [Thanks Ray] These lenses are found for over $300 dollars on Amazon (seen here) and B&H (seen here), but at the listing it sells for just $164. Seller has excellent ratings and checking the feedback shows the seller has sold several of these lenses in the last month. Everything seems to check out fine and it's a hell of a deal.
