    You can achieve that backround blur effect by using the gopro on the phantom now- film at 1080- 60fps, using a number 3 natural density slip on filter (or make your own) and it gets you real close to that cinematic feel when you put it into slow motion. It gets better at the 720 and 120fps.

    I doubt any of the lenses that would work on the backbone would be in weight limit- but the rig is pretty trick just the same.

    Although, at what point is it no longer practical to transform your gopro into something else better designed?

    Now, when they can mount a Phantom camera on a Phantom multicopter, then that would be some snazzy mod.

    Working pretty well for me...

    Got my GoPro Ribcage installed and tested with my Zenmuse H3-2D gimbal.
    It fits fine, just used some longer screws to use the default gimbal/GoPro bracket.
    The stock GoPro lens plus Ribcage is light enough that with my basic testing the gimbal worked fine. I also tried a heavy 35mm F2.0 M12 lens (15 grams versus the stock 6 grams) and it was too heavy for the gimbal to work. So if you can keep the M12 lens around 6 grams you should be good. Now I just need to find a 6gram M12 lens with no fisheye to test with. I have one but it is too short to focus properly in the ribcage M12 ring. Extension tube on the way…

    I don't know about the phantom, but that rig really makes the gopro a kickass video recorder for a superb range of lenses.

    I would love to know exacltly what M12 lens you are using and where you bought it. How sharp is it with the extention tube and where did you get it.

    My company has a phanton and we are thinking of getting the ribcage to get rid of the fisheye look if this all works.

    I have been getting lenses from ebay, readymaderc.com, hackhd.com and a few others. I have yet to find a lens I am happy with to remove the fisheye, as that was also my goal. I think I have a few that will work great but the M12 piece on the ribcage mod does not extend enough to focus all the lenses I have bought. In fact my success rate is pretty low like 25%.

    Anyways, I am having an active discussion with back-bone.ca (the makers of the mod) on Facebook and we should have a solution in a few weeks by extending the m12 part a few millimeter. Once that is done I can probably point you to a proper lens.

    I'll keep you posted...

    Here is another flight I got in with the Ribcage installed [youtube]http://www.youtube.com/watch?v=4qUNYuwZsBk[/youtube]

    It took quite a bit nutting out to get the heavier lens to work on the Phantoms H2-3d Zenmuse gimbal. Ive now got it working nicely, just I'm not quite happy with the video quality of this lens. Ill do some more tweaking and Ill remove the low light filter and see if this helps.

    I'm trying to get a slightly narrower lens view than the stock GoPro3 lens but still try and maintain the highest megapixle setting. Any tips on this?
