Tripod collars by size?
All of the tripod collars I can find for sale list the lens they are
intended to grip, but never the size. I am quite certain that there has never been a tripod collar for the teleconverter I want to grip, so I was hoping to shop by size and "wrap" the teleconverter to make it fit. -- Please reply to: | No nation is drunken where wine is cheap. pciszek at panix dot com | --Thomas Jefferson |

Whats more I don't think there would be enough strength in the converter shell to enable the collar to tighten. |

It is almost certainly made to be supported in this way. -- Regards, Eric Stevens |

It is almost certainly made to be supported in this way. That is in fact my plan B, but the reason is simple: The center of gravity of the camera-teleconverter-lens combo is closer to the teleconverter than to the only grippable area of the lens. The lens is a Tamron 55BB mirror lens. The 55BB, unlike its predecessor, was not designed to have a mounting bracket. Focusing rotates almost the entire barrel except for a portion approx. 3/8" long. This part of the lens is slightly forward of the center of balance of the camera+lens combo even when there is no teleconverter, and is even further forward of the center when the teleconverter is added. The teleconverter is a Tamron 140F; since they no longer sell the adaptall mount version, I had to get a Nikon mount version and add an adapter, but it seems to work. (The Tamron 140F was meant to work hand-in-glove with Tamron lenses like the 55BB; that's why I went to the trouble.) The camera is an Olympus OM-D. I think the 140F is sturdy enough to be gripped. If the mounts on either end of it can't hold up the weight, then I am screwed no matter where I grip the combination. I do think it makes more sense to hang the camera off of one side of the teleconverter and the mirror lens off of the other side than it does to either hang the whole thing one-sided off of the camera or the lens. -- Please reply to: | No nation is drunken where wine is cheap. pciszek at panix dot com | --Thomas Jefferson |

What you want is a bracket which will let you screw the camera via its tripod mount to one end, and a tripod collar round the lens to other. Then beneath the bracket at a point you choose (they have slots which to allow flexible positioning of the mounts) you mount the tripod. Such brackets are used for lots of things like mounting flashes, video lights, microphones, camera pairs for stereo. etc.. -- Chris Malcolm |

None are sold by size, only the model of lens they are meant to grip. Also, the teleconverter has a tab sticking off to one side that the bracket would have to dodge. -- Please reply to: | No nation is drunken where wine is cheap. pciszek at panix dot com | --Thomas Jefferson |

Think outside the box, visit an auto muffler (silencer) shop, they stock all sorts of clamps, do a little modifying. |
