DIY EOS M Lens v1.3 (single/duo lens design)

thingiverse

The fourth EF-M lens is here. Also, it is the cheapest lens that design for Canon EOS M camera. Basically, it is a remix version that combined the DIY Micro 4/3 Lens and the EF-M adapter. It also uses Carson LL-10 cup magnifier for the optical lens. But the larger sensor make the burr effect stronger. Choose the shorter main body and focus ring (end with -15mm and -10mm) for duo lens design and longer pair for the single lens design. Instructions It is a self-supported design and should be printed out in thin layer. 0.1 mm will give you great detail in connector but 0.2 mm also work fine. The one in the uploaded picture was printed in 0.2 mm. Taking apart the cup magnifier and you will find two optical lens. For duo lens design, snap one in the back of the focus ring and snap another in the back of main body. For single lens design, just put one in the focus ring. The optical lens from Carson LL-10 is plano-convex and the one from Dasio is biconvex. All work fine with DIY EOS M lens but have different distort pattern. Also, different orientation of two plano-convex lens can product different distort effect. Now the .skp file for the single lens version is available for download, I build the duo lens version by cutting the stl file in Slic3r.
