camera in vertical (portrait) position on tripod head

[Tracy Storer]

If you put one plate on the bottom of the camera, and add a second plate to the side, and tighten them properly, you can quickly switch without problems. I kept a plate on the bottom of my CG for years without it ever slipping. There is a notch on the outer tightening ring for using a screwdriver or similar as a "cheater bar" to tighten it better.

It is the Bogen hex-plates which have the notch I mentioned

Thanks Herb,
My problem is not with the head, but with the camera plate: the camera swivels slightly when I shove the film pack up.

I'm left handed, so it might be different for anyone else.

As many have said, get the QR plate tight.

I orient all of my cameras (including a Speed Graphic) so that the film holder is inserted from the top. I use one hand to open the back enough to get the film holder started. Than I support the camera from below while sliding the holder into place. Opposing forces canceling movement and all that. No wiggles.

The Austrian company, Lotus View Camera, makes what they call “Vertical mounting devices for panorama cameras” http://www.lotusviewcamera.at/subs/1...ssories_e.html

I am thinking of making something like this for my Phillips 7x17. Perhaps something similar with appropriate changes in measurements would fit your needs.

The standard markins plate for this is the p67U which has a small secondary screw to prevent rotation of the plate. I find this enough on my CG, even using a lesser head than the M20 (which I love, am saving the pennies for a Q3 to replace the cheap light benro for travel...). Otherwise its a custom lipped or ridged plate: there is fellow on ebay krosno65 who seems to knocking them up (http://cgi.ebay.com/4-QR-rail-for-Re...ec27c0cc)--you might try him? (no personal knowledge or commission!)

Find a quick plate who has a screw and a pin, for preventing camera from rotating, then drill a small hole beside the tripod socket of camera body, now your camera will not rotate any way.
