The file 'Yashica Electro 35 GSN Yashinon DX 45mm 1.7 Conversion Kit 3D Printer Model' is (stl) file type, size is 128.8KB.
This is a kit to convert the fixed Yashinon DX 45mm f/1.7 lens from Yashica Electro 35 GSN to Sony E-mount.
Holes need to be drilled on the bayonet mount, aligning with the screw heads.
There is also an optional leaf shutter control lever if you don't mind stripping out all the shutter mechanisms in the lens. Be careful with the standoff pins though, one of them is to stop aperture control ring from free spinning.
Once you removed all the mechanisms, it should be easy to see where this lever should go.
Shutter release lever needs to be cut off, the shutter cocking rod can be removed after removinig the mechanisms.
Screws needed: 3 x M1.6x10mm
