Description
PDFThe Samyang 800mm f/8 mirror lens has an incredible $-to-mm value.
However it is very hard to focus and not very sharp.
Inspired by a blog article I designed this sliding aperture ring.
This aperture ring reduces the aperture helping with focus and sharpness.
The FreeCAD file is included if one need to adapt this design to another lens.
