Why do I feel like I am the only guy using a Leica M8 here?

Congratulations!

You need a UV/IR filter to remove the 'IR bleed'.  The sensor is also sensitive to optical radiation in the ultraviolet range too although that doesn't manifest itself as visibly as the sensitivity to infrared.

SC or MC is really a preference on how you'd like your pictures to look; SC will produce pictures with a more 'classic' look like some older lenses produce because thinner coating generally means less stray light absorbed by the coating and therefore a little more flare like in older lenses.  MC will produce a more modern look with flare minimised through absorption so it depends on your preference. 

You've said it's a Voigtländer Nokton 1.4 II but not whether it's a 35 or 40 mm?

Pete.

35mm.  What IR lens removes the color distortion?

Virutally no regular photography lens removes infrared light - that is why an add-on filter is needed. One piece of flat treated glass that screws onto the front of the lens.

For the 35mm Nokton f/1.4, you'll want a 43mm diameter.

Generally, the IR-cut (IR blocking) filters look a bit strange - they sometimes reflect a pinkish color (that is the IR light and a bit of visible red light being reflected away from the sensor) but transmit light that looks slightly cyan/green (white light with the deep red and infrared light removed) - but may look also greenish viewed at an angle as well. (it is just weird physics ).

Such filters on the M8 will - correctly - make skin less red, make some black or gray or blue fabrics less purple/magenta/red, make foliage (grass and trees) more green and less yellow-brown. Those all being things that reflect a lot of infrared, and can come out too reddish if the filter is not used.

Now, if you want to use the infrared sensitivity of the M8 as a positive feature, you can get an IR-pass filter, that blocks almost all light except infrared. These are very dark red in appearance, sometimes almost black to the eye - but pass "invisible" infrared light to get eerie special effects (screaming pale violet or white foliage, very dark skies). Expect a bit of a learning curve in metering, exposing and post-processing M8 pictures to get the maximum effect, even with the filter.

And just be careful when shopping so that you get the correct filter for the effect you want - true to life colors, or neat infrared special effects.

Excuse my typo.  I did mean filter not lens.  I am pretty slow but not that slow, really.  LOL

And thanks for explaining what I need to kill the color pollution which is an IR cut filter.  I am getting a 43 > 49mm adapter so I can use the 49mm filters I already have on the M8.2.  I am quite thrilled to have the camera on its way, FedEx, out of Kowloon, to me.  I think with the Voigtländer 35mm Nokton 1.4 I'll be set for a while.  Just deciding between SC and MC is what is driving me now.

Is this what I should be buying for IR cut?  It looks right to me.  https://www.bhphotovideo.com/c/product/154798-REG/B_W_65014687_49mm_486_Digital_UV_IR.html/overview

Thanks for your help and all the generous help of you folks on the board.  Und für meinen Landsmänner, vielen Dank, auch.  My German is very rusty but I like to trot it out once in a while.

Yes, that filter looks correct for general-purpose correct colors. IR cut, 486M-type.

One of the nice things about the M8-2 is that it is sensitive to IR light, the use this you need an infrared filter, Hoya R72, B+W 93 (I think) or Kodak Wratten 87 series they are all a little different. These are almost black filters, it is nice using them on a rangefinder. Some folks do IR in color I prefer b&w. The M8 is one of the few unmodified digital cameras you can do IR hand held.

Enjoy it.
