Once the lens is in the retaining barrel, it looks no different to any other lens in a barrel!
How do you adjust the Aixiz, O-Like lenses? I have a whole bunch of Aixiz lens adjustment rings that come in the Aixiz module pack I use to screw tightly onto the end of their barrels. The barrel itself probably has insets on the sides for a flat implement (screwdriver) to adjust.
As I'm near Dave, I would prefer just the lenses. I will get the barrels from him directly.
