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 🙁

@emorydunn Oh, that’s a bummer. Do you have an idea of how far off you are?

@pjonori Looks like it's a whole 3.5 mm! It looks like both my measurements and assumption of how deep the sensor is were wrong.

@emorydunn Yikes! That's a decent amount in regards to optical engineering.

@pjonori It's certainly more than I was expecting. Of course I'm working entirely from measurements with no reference specs, so perhaps it's not surprising.

@emorydunn Seems like a major challenge. My statement was in no way intended to criticize - more to call out the frustratingly exacting precision needed for construction.

@pjonori No criticism taken. I'm gaining a new appreciation for camera construction. I have CAD and a 3D printer, I can't imagine doing all of this by hand.
