The ground glass/fresnel lens on my Chamonix 045n-2 seems to be showing signs of separating. It's still usable, but showing a milkiness especially when viewed at an angle. Photo attached. Is this common? Is it possible to fix, or should I just replace it?

Never mind, folks. Hugo says the fresnel isn't glued to the ground glass. I can take it out and wash it.

Be careful washing it. They're easily ruined by damaging the ridges on the back side of the fresnel from scrubbing or mis handling. Don't ask me how I know :{

It's difficult to tell from your photo, but yes, that looks like delamination on the fresnel.

It turns out to have been a bit of moisture between the fresnel and the ground glass. It was the moisture that was holding the two together, which is why I thought they were glued. After separating them gently, a quick rinse with distilled water and a gentle wipe was all it took to make it all new again.
