[...] Indeed a magnifier won't change the field of view of your lenses but you'll have the feeling to use a 0.73*1.25 = 0.91x camera i.e. a digital M3 sort of. Perfect for 50mm and above but less so for 35mm and wider lenses for which you would need to remove the magnifier or to use an optical or electronic accessory viewfinder. 1 Link to post Share on other sites More sharing options...

1joel1 Posted January 31, 2023 Share #222 Posted January 31, 2023 The longer lenses don't really need coding, 75mm or longer, unless you just want exif data. I have both a thick paper and a metal template. They both work fine and I use flat black paint pen only. The white spots are not needed. 1 Link to post Share on other sites More sharing options...

Good point. I never use Auto ISO so I missed that. 1 Link to post Share on other sites More sharing options...
adan Posted February 8, 2023 Share #225 Posted February 8, 2023 Uncoded longer lenses are not subject to the color problems of <50mm lenses. But the cameras will use 6-bit coding to remove regular luminance vignetting, even with lenses as long as 135mm. I noticed this even with the M9 on introduction day (9/9/09). A 135 used with the lens ID'd showed less wide-open vignetting than without, shooting nothing but a patch of blue sky. Certainly not a big deal for many (including me), but a real effect.

Qlan Posted February 15, 2023 Share #226 Posted February 15, 2023 I will attempt to code my lenses tonight. Can someone confirm the following codes are the best for the following lenses: Voigtlander 28mm f/2 Ultron type II -> Summicron-M 28mm f/2 ASPH (model 11604 - code 011010) Voigtlander 50mm f/2 APO Lanthar -> APO-Summicron-M 50mm f/2 (VI) (model 11141 - code 101001) Thanks!

Or should I use 11672 for the 28mm (summicron ASPH v2). I guess IQ wise, the Ultron is much closer to the Summicron v2. The website is a bit outdated. Edit: it turns out the 11604 and 11672 have the same 6-bit code: 011010. Problem solved! Edited February 16, 2023 by Qlan Link to post Share on other sites More sharing options...
Nimar Posted March 16, 2023 Share #228 Posted March 16, 2023 How to code for a 35 Summicron APO? I couldn’t find the answer anywhere, on here or the handful of websites with 6 bit coding lists. Found a picture of the back of one online its 001101 Coded my 35 APO Lanthar and enjoying the results. Link to post Share on other sites More sharing options...
Syrjames Posted June 20, 2023 Share #229 Posted June 20, 2023 (edited) How would you recommend me (manually) setting my new Voigtlander 35mm Nokton f1.5 lens....? Closest is the 35mm summilux but there appear to be 3 options to choose on my M11 Thank you! Edited June 20, 2023 by Syrjames Link to post Share on other sites More sharing options...

lct Posted June 20, 2023 Share #231 Posted June 20, 2023 I realize you were asking about the Nokton 35/1.5 aspherical lens. It is a modern character lens to which i would tend to apply a 35/1.4 asph profile preferably but i have no experience with this lens sorry. Link to post Share on other sites More sharing options...
Syrjames Posted June 21, 2023 Share #232 Posted June 21, 2023 Yes, it is the modern one, beauuuutiful pice btw... I also thought the same... And, at the end, the most important thing is to have some 'exif' data so I can later on tell which lens is lens (which I like doing everytime i suffer from GAS haha). I will write Voigtlander and see if they can share with me their preference. Best, Jaime Link to post Share on other sites More sharing options...

I would keep the lens uncoded and select a lens profile through the lens detection menu to begin with. 1 Link to post Share on other sites More sharing options...
pegelli Posted July 7, 2023 Share #236 Posted July 7, 2023 Question, what does the coding (or manually selecting a lens from the list) actually change to the DNG on a M246 monochrom body? I did some tests this morning using several 35 and 50 mm profiles (with Voigtländer lenses of that focal length) and I can see some differences in vignette correction between the different profiles, (with the worst vignette when the correction is disabled) but it doesn't seem to do any (barrel or pincushion) distortion correction when importing the DNG's into Lightroom.

rramesh Posted July 9, 2023 Share #237 Posted July 9, 2023 (edited) I’m using the 6bit code for the Summilux 35mm ASPH on my Nokton 35mm 1.5, and it’s fine. Edited July 9, 2023 by rramesh Link to post Share on other sites More sharing options...

That's right - the in-camera corrections by 6-bit are for vignette and color drift at edges, and not distortion. Reid Reviews has stressed this in the past with favor, as distortion correction often has degrading effects on IQ. 1 Link to post Share on other sites More sharing options...

Vignetting may or may not be similar, and that's the only correction expected by the code for a 50mm. 1 Link to post Share on other sites More sharing options...
