Hi Guys, as many of you may know I became the lucky owner of a Canon 500mm F/4.0 L IS USM Lens a few weeks ago, I did post it here as well.
Anyway I also posted a pic of the Gimble Mount that I had made, to hold this monster of a lens, coming in at nearly 5.0 KG's.
Well here are some pics of the mounted lens on the Gimble, which can be moved in any direction with a finger tip, the Lens is totally weightless, and can be moved instantly to any subject or follow birds in flight.
I added a replacement foot from Kirk Enterprises, to the lens and a Kirk quick release plate to the Gimble, this allows the lens to be removed in about 3 seconds.
Anyway have a look and see what you think, the first pic is of a Gimble mount which retails at about $600.00,

I made mine for the price of 4 mower wheel bearings and scrap steel, and a couple of hours in the shed, for $27.00.
