Give this a look, I think it may be just what you need. I use this type of cam mount on my Goldwing Touring Bike. RAM is the leader in mounting brackets and they can mount just about anything... No Pun Intended. Anyway, do take a look...

That kinda looks the HORUSBENNU LX-28T The mount is about the same.. I'm going to purchase a tripod made by Nikon that has a ball mount. I use the RAM mounts on my motorcycle, ball mount and I can get my cam right where I want it...

Howdy, And Happy New Year Everyone. I'm new here and am looking forward to a member, as well as learning from all of you pros in the photography field. I'm new to photography so that makes me a green~horn sorta speak. I own a Nikon D3100 that came with the VR DX AF-S NIKKOR 18-55mm, and "I bought a 55-300mm in all honesty, I love it. I have seen others here poking fun at Nikon owners but hey, That's ok... To each his own but don't over do the poking fun at us please. Anyway, Howdy all, Nice to be here.
