Okay, here comes my definitive film scanning setup:
Two boards of black 19 mm MDF are held together by two heavy duty brackets. These are built for load (150 pounds each) rather than for precision, therefore some shims had to be added.
The Novoflex rail holds the caged Canon R7 and the Laowa 65mm APO Macro in a vertical setup. If I wanted, I could convert it to a horizontal setup with not much effort.
A Kaiser Plano shines its light through a CNC’d opening above which the negative holder will do its job. I can also replace the Kaiser by an iPad that I set with some kind of lavender background that compensates the orange mask to a certain degree.
As always, there is a backside. You can see that I taped the edge of the Kaiser to reduce stray light. Two screws hold the rail…and you might see more holes that allow the rail to be set higher or lower depending on film size, lens and camera used.
And that’s the "heavy gear "configuration. The lens is held in place by two EF to RF adapters, one of which is attached to the front of the lens by a reversing adapter. This time, the Kaiser sits on the baseboard in order to show the space between the base and rail-holder boards. The heavier the gear, the closer you want it to a firm structure.
I might write up a paper with plans and more hints…but not today … and should you have any questions that aren’t answered in previous posts, please get in touch with PM.
