gmaurizio Posted September 16, 2007 Share #1 Posted September 16, 2007 Advertisement (gone after registration) Hi guys, I have been using my old 40mm summicron-c from my old Leica CL. It proved to be an absolutely fantastic sharp little lens! It becomes a 52mm normal lens on the M8. While a uv/ir filter is not absolutely needed, for many editorial shots it would be nice to have an uv/ir cutout filter. The 39mm does not actually fit comfortably, since both CL lenses are somehow unique birds. Has someone found a suitable solution for this problem? Thanks for dropping by...

Advertisement Posted September 16, 2007 Posted September 16, 2007 Hi gmaurizio, Take a look here UV/IR filter for Leica Summicron-C 40mm. I'm sure you'll find what you were looking for!
ho_co Posted September 16, 2007 Share #2 Posted September 16, 2007 Standard Leica E39 filters have a 0.5mm pitch, but both the 40 C and the 90 C take a 39mm filter with 0.75mm pitch, or a series 5.5 held in by the lens shade. Either could be made by B+W on request; may have other sources as well. --HC 1 Quote Link to post Share on other sites More sharing options...
gmaurizio Posted September 16, 2007 Author Share #3 Posted September 16, 2007 Thanks Howard, I guess I will have to talk to Schneider. Was hoping for a simpler solution, but the 0.75mm pitch is a killer.... Quote Link to post Share on other sites More sharing options...
cliffordjim Posted September 16, 2007 Share #4 Posted September 16, 2007 I love the 40 Summicron as well. Great sharpness with the Leica bokeh and if you use it on the M8 with the 35mm framelines it's perfect. I use the 39 IR filter that is screwed into the rubber lens shade (39mm generic) that I had bought for my 50mm Summicron (the 39mm rubber shade screws onto the 40 lens very nicely and the the 39 IR filter screws into the 39mm threaded rubber lens shade - hey you get a nice lens shade and you can use the 39mm IR filter).

lct Posted September 16, 2007 Share #5 Posted September 16, 2007 Want to put a red nose on your dear old 'cron 40/2? No problem, you just need: - a 39mm UV-IR Leica filter (#13410) - a Leica hood #12518 dedicated to the 'cron 40/2 - a 37mm rubber ring - a pin and a die grinder 1. Grind the filter housing of the hood in order to enlarge its inner diameter to 37mm: http://tinyurl.com/rv7w/DSC00720_afterweb.jpg 2. Remove the blocking ring of the filter with a pin or same: http://tinyurl.com/rv7w/DSC00710_afterweb.jpg 3. Insert the glass into the filter housing: http://tinyurl.com/rv7w/DSC00721-afterweb.jpg 4.

Guest tummydoc Posted September 16, 2007 Share #6 Posted September 16, 2007 Why not simply trans-plant the glass from a 39mm UV/IR in-to a Series 5,5 filter mount? Quote Link to post Share on other sites More sharing options...

Because the 5.5 mount is smaller than the 39mm glass. Quote Link to post Share on other sites More sharing options...
gmaurizio Posted September 17, 2007 Author Share #8 Posted September 17, 2007 Thanks so much for the detailed instructions... Much better than a made-to-order filter. Thanks to all Quote Link to post Share on other sites More sharing options...

razerx Posted March 22, 2008 Share #10 Posted March 22, 2008 If it is convenient to use the UV/IR I would but some sizes are either not available or hard / expensive to find. Is the filter absolutely necessary when even Leica supposedly didn't notice ill effects during development of the M8. Quote Link to post Share on other sites More sharing options...

graeme_hutton Posted March 22, 2008 Share #12 Posted March 22, 2008 None of the above is necessary if you carefully screw the 39mm filter straight on to the 40 'cron until it grips tightly...I've been using mine like this for months with no problems. Don't overtighten and you'll be ok. Graeme Quote Link to post Share on other sites More sharing options...
voightL Posted March 22, 2008 Share #13 Posted March 22, 2008 If you managed to get Schneider to make a 39mm filter with 0.75mm pitch, I would like to order two. Maybe you should start a thread to take order for this filter:) Thanks. Thanks Howard, I guess I will have to talk to Schneider.

voightL Posted March 22, 2008 Share #14 Posted March 22, 2008 I tried that & it seems to be holding well but it may suddenly come loose!

Don't overtighten and you'll be ok. Graeme I've personally tried this and wasn't satisfied the grip was adequate, and I think this lens really does need a good hood as it is somewhat flare prone. Series 5.5 filters are available from B+W on special order from B&H if you're willing to wait... Sigh. I think I'm going to go down to the home depot and look at O-rings.

voightL Posted July 14, 2008 Share #16 Posted July 14, 2008 Have been looking for a solution for this problem for a long time & found it in the Heliopan series5.5 filter. Leica series5.5 glass can't be removed from the filter mount. Heliopan series5.5 glass is held by a retaining ring that can be unscrewed to remove the glass. Got an optometrist/optician to grind the glass from Leica E39 UV/IR to the size of the series5.5 glass & BINGO, now got a series5.5 UV/IR filter:) Why not simply trans-plant the glass from a 39mm UV/IR in-to a Series 5,5 filter mount?

benkelley Posted July 14, 2008 Share #17 Posted July 14, 2008 here's my solution... found my leica 39mm uv/ir filter wouldn't screw in at all, but an old b+w 39mm would, and then the uv/ir screwed in nicely on top... so i went to my local camera store and tried out a few old filters. b+w fitted the best, so for $10 I bought it, went home and took out the glass, and now when i use my 40mm i can just screw the uv/ir into the glassless old filter. works like a charm. when i get around to it i'll probably buy a b+w 39mm 486. as i need another anyway, but for now it works fine. ben 1 Quote Link to post Share on other sites More sharing options...

Good idea indeed. How do you manage to fit a hood if any? Quote Link to post Share on other sites More sharing options...
benkelley Posted July 15, 2008 Share #19 Posted July 15, 2008 I've got no hood, alas... I just recently bought the lens–it had no hood with it–and first figured out the filter situation. Anyone have any suggestions for a 3rd party hood that might work? Ben Quote Link to post Share on other sites More sharing options...
Shootist Posted July 15, 2008 Share #20 Posted July 15, 2008 I have 2 of these lenses and a 39mm Leica filter does screw in part way and seems to fairly secure on both of them. As for a hood you could get a screw in 39mm and screw it into the filter. The original hoods are almost impossible to get and I don't know of any aftermarket types that would screw into the threads of the 40C, at least no better then a 39mm filter does.
