I had to do some serious Googling to work this one out, but the best I can come up with is that it is an M42 with a Petri adapter.
Am I right, and if so how do I get it off... do I need a special tool or just brute force. _________________

It's certainl;y the Petri SLR mount, but I can't see anything in the pic to confirm it's an M42 lens with an adapter. Are you certain about that? It would help to know what lens it is. Is there an aperture activation pin? I can't see one in the picture.
If you're sure it's M42 then the adapter should just unscrew, but some force might be needed after so many years. _________________ Peter - Moderator |

It looks like a Petri mount.
I agree with Peter, we need more information to know why you think it may be M42 with an adapter. _________________ I like Pentax DSLR's, Exaktas, M42 bodies of all kinds, strange and cheap Japanese lenses, and am dabbling in medium format/Speed Graphic work. |

Life is like a camera. Focus on what's important, capture the good times, develop from the negatives and if things don't work out, just take another shot. |

Sorry, I should have mentioned it's a Pentacon 30mm f/3.5, which is what lead me to believe it was M42. _________________

It would be very strange indeed if a Meyer lens had a native Petri mount, you are correct there.
The odds are very good that this is an adapter screwed on to the M42 thread. Nothing in life or lenses is certain,
so on this sort of thing one has to make an educated wager.
I have such a M42-Petri adapter myself, the problem is that when the adapter is on it looks a great
deal like the back end of a Petri lens. _________________ I like Pentax DSLR's, Exaktas, M42 bodies of all kinds, strange and cheap Japanese lenses, and am dabbling in medium format/Speed Graphic work. |

If that is a Meyer 3.5/30 then, as luis suggests, that must be a Petri-M42 adapter screwed on it, such an adapter was indeed sold to allow Petri cameras to mount M42 lenses as Petri dropped their own bayonet and switched to M42 so they wanted users of their older cameras to be able to use their new lenses in M42. _________________ I don't care who designed it, who made it or what country it comes from - I just enjoy using it! |
