#323805 Print-it-yourself diopter "flip" holder

Posted by ProfF on 04 January 2013 - 09:08 AM

I have a Nauticam housing for my Olympus E-PL3. Recently, I have been mainly using a 4" wide-angle port, as it fits both the 12-50mm (multipurpose) and the 60mm (macro!) lenses as well as the 9-18mm (wide-angle) lens I originally bought it for. When using it with these newer lens, I wanted to add wet diopter. Recently, Nauticam came out with a product for this purpose (http://uw-foto.ch/im...ages/2484_1.jpg) , but I felt that shelling 220$ was a bit too much. Designing & printing my own solution was much more fun.

The final product is completely made of ABS, except for a single 72-67 step-down ring that provided the filter thread. Unlike the commercial solution, the "base" is not held by screws, but rather by a twist mechanism that locks it into place. It is slightly bulkier than the metal version, but works well. The ABS construction was surprisingly solid, and unlike the metal flip ring (which is heavy) this gadget has slightly positive buoyancy. All by all, after about 12 dives with it I am very happy.

The design can be found here - 67mm frame holder for Nauticam 4 inch wide angle port by nirfriedman - Thingiverse

If there is interest I can also upload it to shapeways and then you could order the printed version directly.

Happy Diving,

Nir

#323551 Favourite Image Of 2012

This year was good, not stellar. I spent more time thinking about my equipment than actually using it :-(

Two favorite pictures, one for its esthetics and the other for capturing an amazing moment.

Happy New Year!
