Sailorcrew Posted December 30, 2010 Share #1 Posted December 30, 2010 Advertisement (gone after registration) Hello, This is my first post. After reading many threads here I purchased an M8.2 along with a Zeiss 50/1.5. Included with it was a Leica UV filter and it works perfectly. I recently purchased another Zeiss lens, this time the 28/2.8 through ebay and it came with a B+W UV-Haze filter, 010M. The first few shots definitely show black as being purple so this must not be the right one. From looking around, the 486 is the one that does the job. Is this right? Should I just get the Leica UV filter or is the 486 B+W, if appropriate, adequate? Thanks for any input. David. Link to post Share on other sites More sharing options...

ho_co Posted December 30, 2010 Share #2 Posted December 30, 2010 Welcome to the forum, David! Glad you found us! Yes, 486 is the correct code for the B+W filter. About half of my filters are B+W, half Leica. Heliopan also makes a UV/IR Cut. The only problem I'm aware of is that some Leica filters (E43, for example) have a slightly different outside diameter than their counterparts in other brands. In such a case, you'll need to use the Leica filter to avoid damaging the lens hood. But that obviously doesn't apply with a Zeiss lens. You're aware that for good results with the wide angle lenses, you need to pay attention to how you code the lens so that the camera can make the right correction, right?

Sailorcrew Posted December 31, 2010 Author Share #3 Posted December 31, 2010 Ho_co, Thank you for responding. Could you please give me some more info on the coding? I've seen the discussions but what exactly am I facing if I don't code the lens? Thank you. David Link to post Share on other sites More sharing options...
ho_co Posted January 1, 2011 Share #4 Posted January 1, 2011 David-- Having lenses coded is recommended, particularly with the M8s and their oversensitivity to IR. For all lenses, the coding will allow the camera apply a certain amount of vignetting correction based on the lens in question. For all lenses, the coding allows the camera to include the lens ID in the EXIF data. That's something we never had with film, but something I found highly desirable once I found it was possible. For lenses 35mm and shorter, the coding is extremely important because the UV/IR Cut technology introduces a cyan drift toward the edges of the image. Letting the camera know what lens is in use (most importantly its angle of view) allows it to apply proper corrections to compensate for the filter properties. The shorter the lens, the more important it is to compensate for the filter effects. Some people find that at 35mm focal length they already need the lens coding; for others, the necessity of the coding doesn't arise before 28mm. Best bet is IMHO to consider the need for coding whenever you consider a lens. A number of independent repair specialists can do the job. When using non-Leica lenses on the M8, one also has to be sure the lens keys the proper framelines, because the camera compares both the lens code and the preview lever location. The quickest source for what's needed is probably Carsten Whimster's Leica M Lens Codes. A recent example of what happens with uncoded wide-angles, or in this case (the same thing) what happens even with a coded lens but when one forgets to switch on the camera's lens recognition, is at http://www.l-camera-forum.com/leica-forum/leica-m8-forum/158530-banding.html.

Sailorcrew Posted January 1, 2011 Author Share #5 Posted January 1, 2011 Hi Howard, Thank you again for your response and insight. I will look at coding this lens, then. I was looking at the Match Technical coder kit to do this by my own hand. Other than the lack of permanency, are there any compelling reasons to no go this route? Thanks. David.

Sailorcrew Posted January 1, 2011 Author Share #6 Posted January 1, 2011 I need more help, please. I just ordered a Leica filter, model 13004 and just realized that it is a UV-a filter, not a UV/IR filter. I think I ordered the wrong one, did I? If so, what model number is the appropriate one? Is it the 13411? Thanks. David. Link to post Share on other sites More sharing options...
ho_co Posted January 1, 2011 Share #7 Posted January 1, 2011 Advertisement (gone after registration) ... I was looking at the Match Technical coder kit to do this by my own hand. Other than the lack of permanency, are there any compelling reasons to no go this route? ... I've always had my lenses coded and have no experience with any of the coding kits. A lot of people use them without any complaints, so that should be a good starting point. ... I think I ordered the wrong one, did I? If so, what model number is the appropriate one? Is it the 13411? ... Yes and yes. Both are the same size, but the 13411 is the UV/IR Cut that the M8.2 requires. (I see that B&H improperly describes it as a 'UVa/IR' filter.)

Clook Posted January 2, 2011 Share #8 Posted January 2, 2011 Hi, I've been using a Zeiss 28mm Biogon on an M8.2 for nearly two years now. I coded this lens myself by printing off a template from a link on this forum and applying the code using a 'sharpie' permanent marker. I recall that the template was originally designed for the Leica 28mm 'equivalent' lens but the markings worked fine for me. I occasionally top-up the markings with a pen.
