In order to access shutter speeds of less than 1s I need a mechanical shutter. I found one on eBay for a bargain price – and it is in good mechanical working order. The challenge was to attach it to the camera as the rubber seal has gone solid.
I first rigged a plastic adapter to put the shutter on the front of the lens. This did work OK, but isn’t very elegant. Next, I looked at putting the shutter between the lens and the camera body. I didn’t want to make too many cuts, or changes to the camera or shutter so fabricated a frame to hold the shutter onto which the lens could be mounted. I only needed to make 3 small screw holes into the lens mounting plate. This has worked well, so will now stain the frame to finish it off. Next step (in the next blog) is to measure/adjust the shutter so I know what speed it is running at.
