Does Leica M9 with Voigtlander Nokton Classic MC 35mm f/1.4 II VM needs a neutral density filter? And if so what do you recommend?

A lens does not need an ND filter. A specific subject sometimes does when you need a long shutter time in bright light.

Thank you jjapv! I should have been more precise with my first question. In fact, I've always put some on my cameras just to protect the glass from scratching, but as I now have my dream camera, I wanted to know if there could be variations in the results with a ND filter on this lens and camera.

For protecting lenses use a protective filter as provided by the major suppliers. Like B+W 007 Use an ND filter if you want to reduce the amount of light transmitted by the lens.

Exactly!
In earlier times i used UV filters for that, now i got the Sigma WR Ceramic Protector and could not find problems, but did not tested in-depth.
But for my Sigma 105mm Macro, not the Voigtlander but i would expect that it will fit also the Voigtlander as long the diameter is correct.

As Jaapv stated, a ND Filter is to reduce light if you want o have slow shutter speed or the lens wide open on a bright day.

I suspect you're thinking about a UV filter. I use them for lenses where the front element surface is close to the front of the lens with little protection, but if it's deep set I don't bother.

But also relevant to your case, I used an IR cut filter on my M9 i.e. a filter to eliminate the IR frequencies which I often found caused skin tone problems with the M9 sensor. The M8 (M8.1) had a major problem with IR, and Leica didn't really eliminate it till the M240.

Thank you for all your answers.

If you want to be able to shoot at f/1.4 in bright sun light, you need at least a ND8 (0.9) 3-stops filter in order to not exceed the 1/4000s limit of the M9 shutter. I recommend filters with good coating like those from B+W.
