ganzosrevenge Posted January 9, 2018 Share #1 Posted January 9, 2018 Advertisement (gone after registration) I know filters are a hot topic.... but I'm for them What would be a nice Series VII filter for an Elmarit 90mm f/2.8? I just need a UV type for protection. Jason Quote Link to post Share on other sites More sharing options...

spydrxx Posted January 9, 2018 Share #2 Posted January 9, 2018 If all you're concerned about is lens protection, almost any one would do. 1 Quote Link to post Share on other sites More sharing options...
ganzosrevenge Posted January 9, 2018 Author Share #3 Posted January 9, 2018 Is there, with re: film, a difference between a UVa filter and a UV/IR filter Quote Link to post Share on other sites More sharing options...
a.noctilux Posted January 9, 2018 Share #4 Posted January 9, 2018 For protection, UVa filter for film use. UV/IR is for use with digital Leica M8 which has weak IR filter on sensor. This UV/IR filter may introduce color cast in film use. Quote Link to post Share on other sites More sharing options...
ganzosrevenge Posted January 9, 2018 Author Share #5 Posted January 9, 2018 What sort of color cast does it render on film? Quote Link to post Share on other sites More sharing options...
Michael Geschlecht Posted January 10, 2018 Share #6 Posted January 10, 2018 (edited) Hello Ganzosrevenge, The idea of a UVa filter is to remove the invisible to people Ultra Violet rays from the light striking the film surface so that the film which IS sensitive to Ultra Violet light rays will not record these rays as additional blue in the image. Meaning: No, or less, color cast. As opposed to the same photo taken without the filter. The image that is produced will appear more like the scene the photographer was looking at than it would if the excluded Ultra Violet rays had been included.

Best Regards, Michael The problem being that UV is normally blocked by the lens, at least by post-1960 designs, so you will not see any difference, except with exceptionally high levels of UV. Like over 10.000 feet in the mountains. Normal film is not -or hardly- IR sensitive, so an IR cut filter is not useful for film and may alter the rendering of red colours.

ganzosrevenge Posted January 17, 2018 Author Share #11 Posted January 17, 2018 B+W produces Series VII and Series VIII multicoated Protection 007 and UV 010 filters.

mmradman Posted January 17, 2018 Share #12 Posted January 17, 2018 Are they drop in and work with the filter ring lock on the old lenses? I have some old Leica Series VIII contrast filters and current B+W Protector, both brands are mechanically identical, I assume same applies to Series VII - smooth metal ring that require some sort of external retaining device, either ring or lens hood, to fix filter to the lens.

ganzosrevenge Posted January 20, 2018 Author Share #13 Posted January 20, 2018 I wound up buying a new B+W MRC 007 Filter Serie VII from B&H. It was a direct drop-in and works nicely with the rest of the system. Quote Link to post Share on other sites More sharing options...
TheBestSLIsALeicaflex Posted January 21, 2018 Share #14 Posted January 21, 2018 Series VII = 48mm screw-in; filters sizes are interchangeable. Lots of options. Quote Link to post Share on other sites More sharing options...
pico Posted January 23, 2018 Share #15 Posted January 23, 2018 (edited) Series VII = 48mm screw-in; filters sizes are interchangeable. Lots of options. I'm afraid that is incorrect. No series filters were screw-in and the VII were not 48mm, but non-threaded 50.8mm which required a 54.4mm screw-in adapter.

jankap Posted January 23, 2018 Share #16 Posted January 23, 2018 (edited) I have found the following table in the Internet. Series VI is correct with 44mm. Of course the mentioned thread is the one of the retaining ring (male) and of the lens (female). The filter itself has no thread. The pitch of the thread differs from the modern E-filters, otherwise it would be too simple. The retaining rings can be found cheap at Ebay. But not new, modern (coated) filters. Jan >SERIES IV 13/16" 23mm filter threads >SERIES V 1 3/16" 34mm filter threads >SERIES VI 1 5/8" - 44mm filter threads >SERIES VII 2" 55mm filter threads >SERIES VIII 2 1/2" - 65mm filter threads >SERIES IX 3 1/4" - 85mm filter threads >SERIES X 4 1/2" 114.3mm ? >SERIES XI 5 7/16" 138mm ? This is the thread diameter. I don't know what the pitch (threads per inch or threads per mm) was. I have heard that is was different than the standard threaded filters of today.

amaitra Posted February 1, 2018 Share #17 Posted February 1, 2018 The filter thread is close to E54. Most of the UV have no threads - needs a retainer ring to hold in place. Good linear polarizers which screw in directly(no retainer rings) are very easily available.. filters that directly screw are available but very few step up adapters to let you use new higher size filters. Heliopan has a 54-58 step up (or is down) adapter. I am still waiting to receive it. I want to use 77mm filters on the Leica R 90/2.8. Quote Link to post Share on other sites More sharing options...

No series filters were screw-in and the VII were not 48mm, but non-threaded 50.8mm which required a 54.4mm screw-in adapter. What he means is that a lens that takes a series 7 filter will also take a 48mm screw in filter. This matches my experience. When I possessed lenses that took a Series 7 filter, there was screw in filter equivalent, and it was either 46mm or 48mm. I forget exactly, but he's correct. You don't always need a retaining ring and separate filter. Edited February 26, 2019 by SteveYork Quote Link to post Share on other sites More sharing options...

[...] True for some lenses (21/3.4 # 11103; 28/2.8 # 11801), less so for others (35/2 # 11309: S7 or E39; 35/1.4 # 11870 & 11871: S7 or E49 upside down in the hood; 135/2.8 # 11829: S7 or E55)...IINW Quote Link to post Share on other sites More sharing options...
Michael Geschlecht Posted February 26, 2019 Share #20 Posted February 26, 2019 (edited) Hello Everybody, The 54.4 mm retaining ring (Thank you Pico.) that holds a Series VII filter on Leitz lenses is a 14161. If you find it as originally supplied on a lens it is most likely marked "Canada". If it has been ordered separately it is most likely marked "Wetzlar". "Most likely" because with many things Leitz/Leica: There are exceptions*. Best Regards, Michael * That is 1 of the reasons that someone invented Leitz/Leica Collectors.
