Sony E-Mount Ultra Wide Converter Cokin Filter Holder Adapter

This item can be used to adapt cokin filter holders onto the Sony E-Mount Ultra Wide Converter. One end clamps onto the lens, while the other end expands out and then slots into most cokin filter holders.

This thing is now marked in progress. The barrel of the thing now has slightly too wide a diameter and the entire thing should be thicker. It is currently functional and in use as is. I used a few layers of thick tape on the inside to get it to grip the camera lens.
