ANYWAYS ,, on my 5.0 MP Varifocal 6-22 mm Lens I bought a 30 - 28 mm step down ring and put just a little 2 component epoxy on the indent at the end of the lens with a tooth pick then
fit the step down ring over the indent and it fit perfectly and on the outside spread a light layer of epoxy over where the ring fit over the indent so just a bit was on the lens making a more secure
fit when it cured and was dry ,, once dry I screwed the CPL filter on and Woopy - D everything was nice and tight and can turn the filter nicely and or take it off whatever you wanted ,, still in the
process of putting together a 3 in. 12 volt monitor for the dash to focus the lens but generally like it where it is but have 2 cameras and will use the filter for the other one ,, just play toys .
That's very similar to the method I used to install my CPL. The smallest size you can get the Hoya HD CPL in is 37mm so in my install I used a 28-37mm step up ring. I used UV curing cement to attach the ring because it can be easily removed in case I decide I no longer want to use the ring.
One thing I did which has proved very handy is that once I dialed in the CPL properly I marked the lens so that I can easily "re-tune" the filter if it ever gets turned out of place accidentally. (which has happened)
