This page describes my effort at finding a way to mount the Rollei electronic shutter size 0 to the inside side of an Arca Swiss lensboard. The idea is to allow the camera to get lenses like the 24mm Schneider digitar close enough to a digital back mounted on the panshot. Since the shutter speed and aperture are set electronically, there's no need for it to be outside the camera. Basically, I'm doing this by means of an adapter that screws onto the front of the shutter and fits through the hole in the lens board. To assemble the adapter to the front of the shutter, remove the five M1.7 tiny metric screws that hold the front cover plate onto the shutter and then put the adapter over that plate so that the holes in the adapter line up with the holes in the plate, and then screw it all down with 5 slightly longer (half centimeter) M1.7 screws. In addition to telling me the size of the screws Rollei told me that the minimum inner diameter for an adapter of this sort is 73mm. SK Grimes is going to machine me a few with the same threads as a 77mm filter on the outside, which will mean a 77mm custom hole in the lens board. Owing to a communications error, I tried an adapter of this sort with Copal 3 sized threads on the outside, and the hole in the middle didn't permit the installation of one of my Rodenstock Apo-Sironar digital lenses to the shutter. I don't yet own the fameous 24mm Schneider digitar. Below are a couple of photos I took of this electronic shutter with an Arca Swiss format frame reducer and an Arca Swiss 6x9 format frame sitting on top of it. Click on them for larger versions. It's clear to me that it would be impossible to assemble a 110mm x 110mm lens board for 6x9 onto a camera with this shutter mounted to the inside of it. Both the lens board and the shutter are too big to fit through the hole. So, I'm having the custom hole made in a 171mm x 171mm lens board for 4x5 which should be no problem for use with the camera as I have it configured.

Here's the shutter from the front with the screws removed, and also opened up. These photos aren't really pertinent to the project, but I thought they migh be of interest anyways.

When I get the connecter through the board added, I'll add more pictures.
