I can’t wait to give this Gopro 3D system a try.  I just read the blog “What you need for 3d video recording with Gopro” and it clearly outlines what you need to shoot in 3D.  In total from scratch it will cost you about $650 if you don’t already have a Gopro HD Hero camera.  Depending on who you are you may find this expensive, but compare it to other 3D cameras (two lens cameras) on the market.  Another nice little camera that is cheaper is the Sony Bloggie 3D that goes for $249.  The problem with this is that its not really a fair comparison.  Good luck getting your action sports filmed with a Sony Bloggie.  You also get the use of two Gopro cameras when your not shooting in 3D, so you shoot double the footage from different angles if your not shooting 3D.  I think that for certain Gopro users like users of the Gopro HD Motorsports will find that thier footage in 3D will be just off the charts.  Just image full 3D from a great mount angle in car on the track.  If you don’t need a mountable camera and want a 3D camera check out the Sony Bloggie coupon.  For more info and deals on Gopro 3D check to see if their any Gopro promo codes.
