Rokinon 135mm universal adapter

thingiverse

This adapter requires removing the whole back of the lens. Everything behind the aperture ring needs to be disassembled. There is a metal ring that attaches to all different mounts and this adapter attaches to the same ring. I`m traveling at the moment, when I can I`ll update this Thing with photos. Printing with layer height 0.1mm should suffice for a good M48 thread. I printed with PC+CF. and got good result. PETG may flex too much and cause sensor tilt. I used 5 layers vertical width. Use 4x M2x8mm screws (I think) and a male-male M48 adapter. Back focus behind this adapter should be 45mm.
