Olympus 8mm Fisheye - Focus Gear

Focus gear for Olympus 8mm Fisheye lens - works with AOI and Nauticam housing.

I think the focus gear designed for the OLY 60mm macro lens by user nirfriedman is a brilliant design. I remixed it to work with the OLY 8mm fisheye.

The 8mm focus gear needs to be installed on the lens from the rear before installing the lens on the camera.
