falkk Posted October 17, 2009 Share #1  Posted October 17, 2009 Advertisement (gone after registration) Dear readers, I am a relatively new user of M8 - I bought a new M8 (early batch, I guess) a year ago.  I just bought a Voigtlander Nokton 35mm 1,2 ASPH together with a B&W UV-Filter. I wonder, if the filter works correctly, or if I just use the wrong white-balance setting? My overall feeling is, that the lens somehow likes red colors. I can adjust that, but when I shot that picture recently, it turned out all in that famous UV-magenta tone... I checked it: the fabrics here should be black, but it is all one tone.  Is that a UV-issue, or do I just use wrong white-balance? Or does that has something to do with the "coding"? Please excuse the quality of the example, but it shows the colors quite well...: Welcome, dear visitor!

Advertisement Posted October 17, 2009 Posted October 17, 2009 Hi falkk, Take a look here Voigtlander Nokton 35mm 1.2 and B&W Filter - UV-Issue??. I'm sure you'll find what you were looking for!
pklein Posted October 17, 2009 Share #2 Â Posted October 17, 2009 falkk: You are using the wrong filter. You need a UV/IR cut filter, not the simple UV filter you used. The M8 is more sensitive to IR (infrared) than many other digital cameras, and this shows up as purple and magenta color shifts. You can't fix this with color profiles or white balance.

falkk Posted October 17, 2009 Author Share #3 Â Posted October 17, 2009 ahh, thanks a lot. than maybe I should have been more specific, when I ordered the filter. I'll go out and get a new one. Â falkk Link to post Share on other sites More sharing options...

falkk Posted October 18, 2009 Author Share #5  Posted October 18, 2009 yes, i think it is a great combination - even with the wrong filter on it the lens is great fun. here some shots from Wuhan / China...

Schneider Optische Werke GmbH . Unless your lens is already coded, you may wish to get this done too. Then you will be able to make the best use of the lens detection and filter correction facilities that the camera can provide. Link to post Share on other sites More sharing options...
falkk Posted October 18, 2009 Author Share #7 Â Posted October 18, 2009 Advertisement (gone after registration) Dear Nicole, thank you for your advice. I will try to get a filter here in Beijing. For the coding, where could I do that? Â Falk Link to post Share on other sites More sharing options...
rickp13 Posted October 18, 2009 Share #8  Posted October 18, 2009 hello falk  not all, but some camera technicians can do the milling and coding. my nokton (early production model) needed a small modification for the m8, and was coded in the netherlands.  greetings from hamburg  rick Link to post Share on other sites More sharing options...
Nicoleica Posted October 19, 2009 Share #9  Posted October 19, 2009 Dear Nicole, thank you for your advice. I will try to get a filter here in Beijing. For the coding, where could I do that?  Falk  Hi Falk, I'm sorry, but I don't know where would be the best option for coding in China, perhaps another contributor to this forum will be able to help you more there? However, there are several other options which may be useful, even if only as a temporary step. There are several kits available which comprise of a template and a pen, by use of which you can code your own lenses. I think that some CV lenses now come with a thin groove in the lens mount which makes self-coding a lot easier and more permanent. There are several other options too, involving stickers, paint or nail-polish. If you do a search in this forum on lens coding, you'll find numerous extensive threads on this subject. Perhaps one of the more knowledgeable members who has the same lens as you may be able to guide you in this respect? Good luck, and enjoy using your camera.

There is also a link in the bottom for printing out a paper coder: Leica M8 Lens Codes Link to post Share on other sites More sharing options...
farnz Posted October 20, 2009 Share #11 Â Posted October 20, 2009 Falkk, Â Please note that Voigtlander 35/1.2 Nokton lenses often need to be modified for use on the M8. This is what Stephen Gandy writes on his CameraQuest website: Â March 17, 2008: The 35/1.2 was introduced in 2003. Once the Leica M8 was introduced in late 2006, some M8 owners reported focusing resistance as the lens focused near infinity. The factory determined this was caused by the rear element guard sometimes binding with the focusing mechanism, and issued a retrofit parts replacement. Â The link to the page is here and you need to scroll down to the section with the red heading: 35/1.2 Aspherical Nokton, which is about half way down the page. If you haven't used your Nokton at infinity then you may not have noticed the problem. Â Pete. Link to post Share on other sites More sharing options...
rickp13 Posted October 20, 2009 Share #12  Posted October 20, 2009 re pete's comment:  as a guideline, the modification for m8 focusing and 6-bit coding cost euro 105 including tax and postage to me.  hello falk not all, but some camera technicians can do the milling and coding. my nokton (early production model) needed a small modification for the m8, and was coded in the netherlands.  greetings from hamburg  rick Link to post Share on other sites More sharing options...
wilfredo Posted October 20, 2009 Share #13  Posted October 20, 2009 Here's a picture of a friend I took with the 35mm f/1.2 Nokton on my M8. This lens was not coded. None of my M lenses are coded and my photographs have not suffered one iota. However, you do need the UV/IR filter to fix the Magenta issue.  I believe coding is most important with very wide lenses. I haven't needed it. Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members!
