Arca-Swiss style Q/R plate for my A-S 4x5greenspun.com : LUSENET : Large format photography : One Thread
Well, give a monkey a 4x5 and he'll bother you until the end of time with questions.
While doing a studio assignment for school today, I noticed that my Discovery twists around on my bogen (3047) hex Q/R plate. Today's assignment was a series of shots that consisted of a cube with light at different angles. Easy and simple, this should've taken just a few minutes, since once everything was set up, all I had to do was change the lighting and take another meter reading. But due to the twisting, I had to re-compose almost every shot. No matter how careful I was putting my film holder in. I don't have enough cash for a A-S ballhead (nor am I sure that a ballhead would be best for me). But what is the best way for me to get a non-twisting (arca style) Q/R system on my Bogen head? And what plate would I need for my Discovery? The RRS web site isn't any help. The Kirk site is better, but everyone is so stoked on RRS I thought I should at least compare the two.
I just hope that someday I'll be able to contribute something to this forum other than questions.

Really Right Stuff sells Arca style QR in several lengths. You might also want to try the Bogen /Manfrotto # 410 geared head instead of your current head.

Hi Josh! If I understand your question right, your problem is twisting between the rail and the Q/R plate, not between the Q/R plate and the head. I also use the bogen hex Q/R plates and had the problem of twisting between rail and plate. I'm not familiar with the Arca Discovery, but my Arca B 4x5 rail has two holes for mounting (3/8 and 1/4). So I drill a second hole in the hex Q/R plate to fix the rail with two screws. No twisting anymore.
I'm not quit sure, but there is a hex architectual plate (bogen 3267) and maybe you can fix your rail from the side. I have not seen this plate, but maybe it's works and prevent twisting.
Sorry about my bad English, but I hope you understand what I try to say.

RRS makes a Arca-Swiss-compatible quick release for retrofitting to other tripod heads. It may be possible to remove the existing quick-release from your Bogen head, then fit the RRS release. I recommend that you call RRS and discuss this with them.

Bogen sells a hex plate with a lip on it that prevents camera twist. It should work egually well (read on) for 35mm through 8 x 10. Two problems with it are that a) the lip blocks the opening of 35mm camera backs like my FE2/FM bodies; and b) the thumbscrew on the bottom prevents the plate/camera combination from resting flat when dismounted from the head. The Kirk hex quick release plate solves both problems and I have used it on Nikon, Mamiya and Arca cameras with equal success. The RRS might do as well, though I have no experience with it. Why Manfrotto can't figure this out for themselves is one of nature's mysteries.
