DOF Adapter

I build this adapter 4 years ago.

The 35 mm adapter consists of a junction box painted black. On a black PVC plate a Nikon focusing screen.

 

The Pancake motor from an old Pager

 

Pvc panel with Nikon "Type D" focusing screen.
Ower the four threaded rods I can set the distance between the Ground Glass and the optics.
And the pancake motor for vibrating.

I used two aluminium tubes with 12mm diameter and +- 50cm length
I fixed the tube clamps on a PVC board but you could use wood too.
The hole on the left is for fixing the camera
