Sony NEX Pinhole Lens 24mm 50mm

UPDATE: I have added a new part for a 50mm (75 equivalent) lens. I used a 300 micron pinhole from Lenox Laser. Also i have a new 3D printer and reprinted my parts at much higher quality.

This is an NEX camera mounted pinhole lens. The mount potion of the lens was designed by NHFoley and can be found here:

I designed the front half.

It is sized to receive a pinhole lens built by Lenox Laser. The following link takes you to their page. http://www.lenoxlaser.com/index.php?dispatch=products.view&product_id=72

I went with the manufactured pinhole for the most precise pinhole lens that could be made, but could have easily made my own pinhole. With this part, and a 200 micron pinhole, the most accurate pinhole diameter vs distance to sensor is achieved for a 24mm (35mm equivalent) lens; Atleast according to the following calculator.

I found the lens in quite sharp in terms of pinhole standards and have attached a few of the images I have taken with it.

The design has been repaired in NetFABB for an acceptable Mesh.

Hope this design works for you!
