Well, I can confirm – I did in fact get my cage. Haven't had a chance to go over it much and use it in the field, though. I can say that my Jag35 rail system doesn't fit with the cage (I didn't necessarily expect it to), So if anyone knows of a rail mount that will fit under this, please let me know.

I have the redrock dslr baseplate and it works. Of course, you have to unscrew it if you want to change batts, but that is another issue...

Here is my short review of Gini GH2 Cage + Rig:

@mrbill , please check this video i made about mounting options : http://www.personal-view.com/talks/discussion/comment/60569#Comment_60569

how do you handle base plate mount? Is there still acces to the battery?

@mrbill thanks looks good! (I'd prefer it all black.. )

@feha - I have external batteries via the dc-coupler that last a whole day, so not too worried about losing access - it's the lens movement using a follow focus I'm trying to minimise. Really like the cage!

@mrbill , i bought from eBay , but they don't have it on the list this cage+rig at present time. There is no one to sell in Europe, so i always have to pay import tax too :-( Their new website: http://camera777.com

@rockroadpix , if you check images above the Varavon GH2 loupe wont work, I don't have the uni version it may work ....

Been living with the cage for a couple of months now, and am loving it. As regards mounting the cage on 15mm rails, I bought 2 of these -

These fit to the bottom of the cage nicely, and the cage is absolutely rock solid. The rails in turn I attach to my camera cheeseplate, so it's a very quick system to use. This method does partly obscure the battery cover, but I use one of the big batteries described in the gh2 powering post via the dc coupler and a voltage step down box, so it's no bother. Recently bought a jag35 top handle, and the whole thing feels great to work with - highly recommended bit of kit.
