Anyone using a Voigtlander 150mm f/4.5 lens?

I'm looking for info regarding using filters for this lens. A 39mm filter is slightly too small and a 40.5mm is fractionally too large. I don't have anything in-between to try. There is a thread on the inside of the front lip. Anyone here using this lens? Thanks.

Yes, but I've never tried fitting any filters on it. I'll check and see if I can find anything that matches in my filter box.

Although there are threads, it appears that it could be a 42mm push-on.

On some old lenses the threads are only there to allow the front retaining ring (with the lettering on) to screw in, so would be some sort of oddball size, not really designed for filters.

You could always do it the simple way and just blu-tack a 49mm or 52mm filter onto the front.
