DIY Micro 4/3 Lens v2.1, Duo lens design

thingiverse

Just get a 10x cup magnifier (Carson LL-10 or a clone from Daiso store) and you are ready to make 'another' new lens for your Micro 4/3 camera. Basically it share same components as DIY Micro 4/3 Lens v1.1, but the main body is 15 mm shorter and focus ring is 10 mm shorter. By using both optical lens from Carson LL-10 (one on focus ring, another mount on main body), the focus length will be around 42mm. A shapeways version is available here (http://shpws.me/z474) Instructions It is a self-supported design and should be printed out in thin layer. I print out mine with 0.1 mm layer height but 0.2 mm also work. Taking apart the cup magnifier and you will find two optical lens. Take one and snap in the back of the focus ring and another snap in the back of main body. The optical lens from Carson LL-10 is plano-convex and the one from Dasio is biconvex. All work fine with DIY Micro4/3 lens but have different distort pattern. Also, different orientation of two plano-convex lens can product different distort effect.
