Leica M10-P and Voigtlander 50mm F/1.2 Nokton - Lens Profile?

Hi All;

I just picked up a Voigtlander 50mm F/1.2 Nokton lens for my M10-P and was wondering which Leica lens profile that I should dial into the menu?

Would the 50mm F/1.4 Summilux be the correct one or is there a specific lens profile that works better?

Thanks!

You'll get better results with making custom lens adjustments. While aperture and length are the same or similar, what the lens correction fixes are things that can be very different between different lens designs: distortion and vignetting.

Hmm..Never done that before. Any sort of write-up on how to perform that on a Leica M10? There's nothing in the menu other than lens selection.

Are you talking about a lens profile in post?

I doubt there is any "correct" choice, because it will be wrong whatever you choose. I would probably select the "50 f/1.2 11820" from the menu list, which will show up as "Noctilux-M 1:1.2/50" in the picture's EXIF info. 

If you use Lightroom Classic, you can manually select the correct lens profile afterwards: "Voigtlander Nokton 50mm f/1.2 Aspherical".

And if you use for example the LR "LensTagger" plugin, you can change to the correct EXIF name as well. But it is of course a bit cumbersome to do this with all pictures you take with this lens.

Personally I like the CV 50 1.2 as it is so I'm really only choosing a profile to have the focal length in exif. If you choose something like a Noctilux or Summilux it WILL permanently modify the file with the selected profile. It'll be built into the DNG. You might no get the result you want as a lot goes on with some of the profiles. Less with others. I haven't done it yet but what I usually do is....

Take a shot with the same setup which should be a blank white wall wide open, at f5.6 and f11.

Do one with no profile and then one set with each of the 50mm profiles in camera by setting them manually.

Load the files into your processor of choice. Spend some time comparing them. you don't have to match the no profile base but it's a good starting point.

Choose the set you prefer and then either code the lens to that profile or manually (or preset?) set that profile each time you use the lens.
