The next step is finding a new lens. The 85mm that came with it doesn’t have PC sync and my 150mm is too long.

I think I've settled on the design for the real adapter. The goal is for it to be easy to make, ideally in a single CNC run on the back side.

The 65 mm lens arrived so I was able to properly test the adapter. It's safe to say I do not have the sensor registered to the ground glass correctly 🙁

I'm going to have to suffer through the "live" view on the back to figure out whether the adapter is too thick or thin.

Using my professional-grade Sensor Registration Marking System (painters tape) I have a new offset of -3.5 mm.
Now to wait 3 hours for a new print. mastodon.emory.coffee/media/RM

After a couple of near misses I think I might have the correct registration offset. The current math says I need to offset the adapter _inside_ the body of the camera.

The adapter does indeed need to be inset by 0.8 mm. With one final print last night I was able to confirm that the registration is correct!

I painted the adapter “photo black” and the contrast in the images is definitely better.
Ideally it would be printed out of a black plastic or even metal. mastodon.emory.coffee/media/on mastodon.emory.coffee/media/Y-
