Nokton 35mm f/1.4 Classic MC - Coding Question

[ryan1938]

I've searched and couldn't find anything. Sorry if this is a repost...

 

But, I have a Nokton 35mm f/1.4 Classic and am getting ready to stab it onto my new (to me) M8. I'd like to code it, but am not sure of what the code is. None of the online databases seem to include this lens.

 

Does anyone have this particular 35mm Voigtlander? If so, what code did you use?

 

Thanks!

There is a tool kit might help you, but i never own it before....

Of course not, since it is not a Leica lens. There is no code for the Nokton 35 mm 1:1.4.

35mm lenses should not need coding to correct for the effects of using a UV/IR filter.

 

If you want to code it to get a lens type in the EXIF - then I suggest you experiment with the published set of 35mm codes - if none of these are OK then use lens detection ON (without UV/IR).

I have my Nokton coded as Summicron ASPH. I did that only because I want the focal length information in my exif data. I don't think coding is needed other than that purpose at this focal length.

No kidding? I was using this chart:

 

Leica M Lens Codes

 

Would it make sense for me to code mine as a Summilux-M 35mm f/1.4 ASPH since the specs match my Nokton?

I went ahead and coded it as a Summilux 1.4.... Unfortunately, it doesn't seem to be working - If I take a shot at f1.4, the file lists that same shot at f2.8.

That's because the aperture is a guess. There's no aperture linkage between the body and the lens so the camera attempts to calculate the aperture. The way it does that isn't guaranteed to be accurate.

My Nokton Classic 35mm f/1.4 SC came as a used lens. The previous owner engraved the lens coding with a diamond tipped bit using a Foredom high-speed hand tool. The lens is coded 011101 for the Summilux ASPH 35/1.4 - EXIF just says 35mm. The rough dots were filled with flat black enamel. M8 recognizes the coding, works fine...

That's the code I use. How do you know if the camera recognizes it or not?

You see it shown in the Exif data.

Here's a shot of my exif data with both lens detection on and off... I'm guessing my coding did not work - correct?

A way to know, in-camera with photos on a card, is hit the Play button, then Info button, and the focal length should show at the upper right corner of the screen.

 

But, Ryan, it does look like your coding isn't being recognized. Did you use the Coder tool? Nice black Sharpie marker?

Yes, I did... Maybe I should try to remove the ink and start over...

[stunsworth]

Not all pens are opaque to the IR light used by the sensor. I had to try a couple before I found one that worked. If the ink isn't opaque the sensor won't 'see' the mark.

I'm using a new sharpie... But I'll wipe off again and try something else.

[stunsworth]

The other thing is that the positioning of the marks is quite critical.

 

Personally I'd try the lens uncoded and see if there are any colour shifts towards the edge of the frame. If there aren't then I'd be tempted to leave it uncoded.

[ryan1938]

I'm not seeing any color shift... Maybe I should just leave it alone...

Glad your enjoying that m8:)

Don't sweat the coding on this lens.

Hallo,

Look here: Leica M

I got it from a GREAT seller... Give me a bit to figure this thing out and I'll post some images. You guys will have a ball making fun of my lack of talent!
