Arca Swiss Pico Lens Compatibility

[vjbelle]

I recommend you thread your Copal 0 shutter onto an adapter, rather than dropping it through a hole and locking it on with a ring (as one would do with a lens board). There's no advantage to doing that for a case like this. If you're worried about the lens twisting off the threaded adapter board, you can still put a Copal 0 locking ring on after it's threaded to the adapter.

Copal 0 thread is M32x0.5mm. If you like the idea of using M65x1 tubes with the threaded coupling I described, then this is the part you need:
https://rafcamera.com/adapter-m32-5x0-5-to-m65x1 It's an adapter with Copal 0 female threading and male M65x1. The rest of the parts @Doppler9000 listed will fit onto this.

I found all of the parts to get the lens attached to the 60mm tube but I have not found a way to attach the tube to the lens plate. There is no adapter that has a male thread extension so that I can attach with a Copal '0' retaining ring.

For attaching the lens to an adapter, it occurred to me this morning that you might be particular about the orientation of the lens once it is mounted. I don't sweat that because F-Universalis boards are square; I can put the board in the position I want (i.e., aperture scale up, down, left, right). The problem with the threaded plate for the lens I recommended above is that it ends up where it ends up. To avoid that, you can go with the adapter plate that @Doppler9000 recommended, which is a "clean" hole (RAF calls it a "bore") that is the size you would have on a Copal 0 lens board. That's the 34.6mm you mentioned. Here is the one you'd use: https://rafcamera.com/adapter-34-6mm-to-m65x1m As you'll see from this drawing, it has a clean hole in the centre, and M65x1 threads on the rear. You would drop your shutter through the hole and lock it to the board with the ring -- just like you would with a lens board for your M-Two.

Rob..... here is an image of my camera with the shortest lens I am going to use with it ( 40mm Rody HR W ). You can see how far the back is from the center of the tripod and this is the closest it will get. As lenses get longer the distance becomes more rearward adding even more weight. My 120mm Asph moves the rail backwards so that only 2cm of the rail is showing in the front. That produces a lot of stress on gears.

Here is my way to mount my Pico on my d4 head so that the center of gravity is almost directly above the tripod head. This can mitigate some of the rearward load that put stress on your tripod head.
To do the above, I align the universal plate flush to the front edge of swing/tilt housing. Then, I mount my Pico by clamping the rear part of universal plate to my d4 head. The fact that the universal plate provided is longer that swing/tilt housing and it does not interfere with rise and fall when mounted as described above, leads me to believe that it is actually Arca Swiss intended design.

Thanks for this. I just got a Pico and used this setup approach.
