TomasSel Posted June 12, 2023 Share #1 Posted June 12, 2023 Advertisement (gone after registration) Hi! I am new to the forum. I just purchased a Summarit that came with an e41 filter that I am having trouble identifying. It appears transparent at first glance but once you tilt it it has different colour casts. I would assume it is a Skylight / Ir filter, but the fact that it is engraved with a "1" confuses me. Every other e41 UV filter I could found online is has a UV engraved. Thanks in advance!

luigi bertolotti Posted June 12, 2023 Share #2 Posted June 12, 2023 Leitz made E41 filters in two colors that had different densities : Yellow (graded 0,1,2) and Red (graded 1,2,3) : yours could be this one (red #1 was coded XOOUI, then 13190) 2 Link to post Share on other sites More sharing options...
nitroplait Posted June 13, 2023 Share #3 Posted June 13, 2023 That magenta reflection reminds me of the infrared-cut filters Leica issued to remedy IR issues on the M8. Since it is Leitz branded it couldn't be one of those of course. I don't know if IR-cut filters existed before digital. 1 Link to post Share on other sites More sharing options...

Thanks for the reply. In that case shouldn´t I be able to see the colour tint when putting it in front of my eye? Here is a picture of the filter hold in front of the camera for reference.

a.noctilux Posted June 13, 2023 Share #5 Posted June 13, 2023 Not fact, just guessing 😏...here. I guess that the "1" filter mount was equipped with non original glass as seen in the first image, it's UV/IR cut type. Maybe to use the Summarit 5cm with M8/M9. When I used my M8+Summarit 5cm (without IR cut filter) I found that this particular lens is very IR sensitive. Link to post Share on other sites More sharing options...
wizard Posted June 13, 2023 Share #6 Posted June 13, 2023 (edited) I am pretty sure that this is neither a red filter nor a yellow filter. From the slight rose color tint I suspect it could be a Skylight filter, but in one of the above photos the filter glass seems to have a slightly green tint to it, which in my view points to an IR cut filter which Leica issued for free to M8 users at the time.

TomasSel Posted June 13, 2023 Author Share #7 Posted June 13, 2023 Advertisement (gone after registration) Thank you all for your responses! I believe it is IR filter as well from everything I have seen so far. I have never hear of anyone replacing the glass of a filter so I guess the safest would be to assume some sort of production mistake? Link to post Share on other sites More sharing options...

Yes, the tint points to this, and the picture in #4 too... but the filters provided for M8 were not marked "Leitz Wetzlar" (I had 3 for my M8, years ago) , also, I doubt they made an E41 version... so probably is a glass transplant, as suggested (I had a B+W UVIR E43 for my M8... and vaguely thought to transpant its glass in an original filter mount for Summilux 50... but thought of too long, and M8 was replaced... 🙂) 2 Link to post Share on other sites More sharing options...

Bought an old Leitz chrome yellow filter for my Summarit 1.5/50 lens and had Heliopan, well known maker of high quality filters, fit a new multicoated UV filter glass into the old filter ring. Still have the old yellow filter glass, so could reverse the operation if desired. 1 Link to post Share on other sites More sharing options...

Don’t want an IR cut filter, I use a “black” red filter to cut out everything except red light. Link to post Share on other sites More sharing options...

One of few Leitz/Leica M/LTM lenses which happend to have R engraved on the dof scale ( between 1.5 and 4 ). For film IR this would help a lot not to "guess focus" but use RF then move the ring to R mark. Welcome, dear visitor!

Purely out of curiosity do you happen to know whether the earlier 50mm f1.5 Xenon was threaded for 41mm filters or did it only accept the bayonet-fit type? Thanks in advance! Philip. EDIT : Just FWIW I've a couple of both styles which I use with my Summarit. I'm not a fan of the latter type as mine can occasonally un-clip themselves far too easily...

luigi bertolotti Posted June 14, 2023 Share #14 Posted June 14, 2023 (edited) You mean Xenon like this one - unthreaded mount : Welcome, dear visitor!

Michael Geschlecht Posted June 15, 2023 Share #16 Posted June 15, 2023 Hello Philip, Leitz lists: Yellow: 0 = XOOAM, 1 = XOOBZ, 2 = XOOCN & Graduated Yellow = XOODA Ultraviolet = XOOFB Green = XOOGP & Graduated Green = XOOHC All are bayonet mount.
