M9 Coding for Zeiss 35mm C-Biogon 2.8

[jsrockit]

I was wondering what Zeiss 35mm C-Biogon 2.8 owners are coding the lens as for use on the M9. What's working best?

35mm summicron asph.

If in doubt do your own tests with various 35mm settings and shoot a white wall, it's not rocket science.

I would use the six-bit code for a 35mm Summarit, which will get you to the nearest wide-open aperture.

That would be good if the Summarit code was available.....which I believe it isn't

You can read the codes off this shot from the Popflash store:

6-bit code for C-Biogon 35mm

I use he 6-bit code for Summarit-M 35mm f/2.5, which is 101011. I mostly use it for exif data rather than correction of any optical aberration. the C-Biogon 35mm is a fabulous lens.

It might not be rocket science but it sure is boring. I don't shoot tests unless I think something is wrong.

If you want to pick a Leica profile from the menu in the M9, the 35mm f/2 11310/11311 one works fine.

I don't code it, none of the menu options worked for me neither - I always had some color inconsistency around the edge (easy to see with lot of snow around). My solution is corrective profiles in C1. Many times I correct only the color cast and leave the vignetting to its own fate.

Coding matters most for my 50 C Sonnar and for my 21 C Biogon. I've been coding 35 Summicron ASPH just because it's new and sharp! The Summicron profile produces indistinguishable results.

Zeiss recommends 28/2.8 11804/11809.

This is a bit of an old thread, but I just did a test shooting my wall and going through some codings and also using CornerFix.

Could be helpful for some perhaps!

Thanks Kenny. Nice tests. I downloaded Corner Fix months ago and in my 10 day break I might learn how to use it for the 21 C Biogon.

 

[zleica]

That's very helpful! Thank you for sharing.

Thanks!

I was a bit reluctant to dig into it, but I have to say the most worst part was taking the shot of the wall.

CornerFix was very easy to then deal with when creating the profile for the lens - one click really. I have yet to try it in my normal workflow though - I'm a bit reluctant there, not really wanting to involve another app, which is why I am more leaning towards using a manual coding in camera to get rid of the color shifts but leave some of the vignetting. I think I could override the 28mm exif while importing perhaps.

As I'm using Aperture I also got the green tint on the CornerFix'ed images I tested with, so I had to enable the hack that appends "CornerFix" to the camera model EXIF, and I don't really like that either.
