I've found myself wanting some type of rail that would connect the body of my F5 and any lense with a tripod collar. I have noticed a lot of vibration when I use longer lenses in addition to teleconverters or the like.
It seems to me the setup would be much more stable/stiffer if I had a rail that mounted to the body and the lense collar at the same time and then mount that on the tripod.
It would have to be adjustable in length to fit different lenses as well as the length change you would have when attaching teleconverters, macro extension tubes, etc.
Does this make sense and is there such a beast? Who makes it?
I'm using the Mafrotto 3246 tripod & 3275 Geared Head w/RC4 Quick Release.
Thanks for the link. I'm login into it as I type this.
It just seems it would be much more stable if there was a way to tie the body and lense together at the same time. I have been using the lense collar mount with longer lenses but sometimes it seems to still shake a bit. I noticed it most when I mounted a Kenko 3x teleconverter with the 80-400mm on the F5 and trying to take pictures of the moon. I used the electronic remote as well as using the mirror lockup and it still seemed to have some shake/vibration.
The collar on the 80-400 is famous for not being difficult to tighten enough for stability. Kirk makes a replacement collar, but it is impossible to put the lens shade in an inverted position onto the camera when the Kirk collar is mounted. RRS suggests that adding one of their knobs to the existing collar will allow you to tighten up the collar more by providing more leverage, and that's the route I've followed.
It seems to me that the more gear you put into the chain between tripod and camera, the more chance there is for vibration. Also, the vibration may be due to the existing tripod and connection. I've found that an ARCA-Swiss type ballhead and a RRS plate, together with a tightened collar, reduce the vibration from that of other mounting systems like the Bogen Quick Releases.
There is another replacement collar by Burzynski, available from Isarfoto.com in Germany. It has a low profile and allows for reverse lens hood storage unlike the Kirk collar. This collar has a couple of other issues, however. The channel for the rotating pins isn't keyed so the collar can slide back freely in any orientations (the Nikon collar has to be aligned to a specific orientation for removal). The clamping knob is even smaller and less textured than Nikon's. You can get a firm clamb by finger tightening, but a better knob would make this much easier.
I have one question about this body lens mounting rail. How would you change from a horizontal to a vertical format? Flop the whole thing off to one side of the tripod head? Kirk made a similar mount for the early 80-200 push-pull lens and camera body. Not sure how well it sold with the format changing problem.

Hmmmm.....I don't know. I had not considered that but it's a good point. I was mostly frustrated with my attempts at getting a decent shot of the Moon which started me on this idea.
