Hi,
I bought this in a charity shop because it came with a Hoya UV 40.5mm filter but what is it? The other side is flat with 40.5MM printed on it and in all it's just under 2½ inches in diameter.
Regards, David

Is it an adapter for the Cokin square filter system?

Adapter for some filter or compendium holder system - there have been many mutually incompatible ones around. The small Cokin holders were immensely popular among 1980s amateurs, but if it comes from a (former) pro, it is more likely to be a adapter for a 75mm gel holder.

That's the right size for Cokin A series. My Cokin P is another inch wider. Dave I believe that adapter fits one of my 50mm early Canon screw mount lenses.

Thanks everyone.
It makes sense as I've never bothered with filters (but like to have them for when I sell cameras). What baffled me was why anyone would want to screw a metal plate into the filter thread...
Thanks again. Regards, David

Just a thought, that thing is no use to me, so if anyone in the UK wants it, just ask.

Just to chime in another theory I bought a Ring Light from Amazon a few Years ago... it looks very similar to the filter attachment for the Main Unit that would hook onto the extended collar. (There were a number of different sizes included from 49mm - 72mm if I'm recalling correctly.) I imagine the same system in which the Cokin filters work, though I have very little experience with them.
