Description
This attaches as graflok extension and accepts a standart focusing screen. Makes the whole setup easier to carry and swap while reusing original ground glass.
Use two M2x16 with captive heads for things that focusing screen grabs on.
Warning 1: Tight tolerances for focusing screen. You may have to use XY comp for this to work properly.
Warning 2: I designed it for multimaterial supports. If you don't have such luxury, just cut off the aligning bump on camera side, it's not that important.
Warning 3: this uses 20.2mm offset, which is different from official shim offset, but that's what the community arrived to. It works for my lomograflok and camera and achieves perfect focus at wide open, but it may not work for you. In this case, please leave a comment with some measurements.
