"Permanent" Filter Adapter

In this project, a filter adapter needed to be secured to the outside diameter of a lens casing. Typically a slip-on adapter would be used, but due to the nature of the wide angel optics, this could potentially cause vignetting. Additionally, the photographer was planning to use his lens in the vertical position and wanted to be certain the weight of the filter did not pull itself off the casing.



The solution was to use set screws to allow the adapter to be “permanently” secured to the casing. Each set screw features a plastic tip so as to avoid damaging the lens casing.
