Thread compatability: Leitz/Contax?

[Rich Ullsmith]

I'm looking at a 55mm Leitz filter for my Contax G2 21mm lens. Are these threads compatable? When I say "I'm looking," I mean shopping online and I can't even see if the filter is threaded or bayonet. Thanks up front for the help.

Pretty sure it's threaded.

One reason I ask is that a friend of mine gave me a load of Leica SLR stuff (not kidding) and the filters are held in by the lens shade. The one I am looking at appears to have a thick enough flange to be threaded, but I can't be sure. I asked the seller a question, but am waiting for a response.

The Contax G stuff is modern, so you'll have threaded filter rings and not any of that series filter stuff -- that's the big pain in the a** in using my old Leicaflexes and lenses, though they're great otherwise. By the time E. Leitz was using 55mm filters they'd moved beyond the series filters and to "normal" filters. And I'm about dead certain that the Contax lens threading will be fully compatible with the Leitz filter.

Nick, I did go back and look, and I really think it is threaded.

The deal with the free Leica stuff is a story I'll tell sometime. I'll probably auction the stuff for charity after he passes, as it was clear he really wanted me to have the stuff, and I didn't have the heart to tell him that I really don't need it. I'm talking about a sedan trunkload of stuff. It was a weird little philisophical dilemma. Later, he dropped some stuff off with my wife, a bunch of worthless darkroom stuff but he told my wife it was his fathers and he was a little weepy about it. It's not like he has a terminal disease; he's just going digital (!?!) I drop him a print a few times a year and tell him how great his stuff works (as I'm sure it does) and he is happy as hell about it.
