I need to make some refinements to the 3D printed adapter, but the initial prototype works well. https://mastodon.emory.coffee/media/JSLhkTDzqqFjupP6n04 https://mastodon.emory.coffee/media/_hPkDjlr__ItYUpKhrk
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.
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. https://mastodon.emory.coffee/media/on_V4xY7cJcMISElnp0 https://mastodon.emory.coffee/media/Y-LOKXBjR5TwJwOv5oE
Just for fun, a quick recording of state of the art live view, circa 2008.
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. https://mastodon.emory.coffee/media/RM_Xsuzvps09NVEUE_0
