Non coded lens and IR/UV filter, What setting?

[chrishayton]

Hi I just recieved my Uv/IR filter for my vc 35mm f1.2. the lens isnt coded so lens detection is set to off.
What setting should it be on?
Bit confused...

Oh btw its a Leica 55mm with step up ring not a B+w filter

Thank you

Which digital M do you own?

Set to Lens Detection - On+UV/IR.

Sorry I have an m8

So I set it to that even though the lens isnt coded?

 

[kbg32]

Yes, that is what I do.

 

[chrishayton]

thanks. I might hand code my 25mm when the filter arrives but dont think Id need to code the 35mm

You really should code anything wider then 50mm. If you are proficient in Photoshop etc., you can do away with the cyan vignetting.

If your lens has no 6/bit code set to "OFF"

I am currently using this lens on M8 w/ B+W 486 filter, although I typically convert to black and white. There is, as I suspect you may have discovered, a screw on the mount which makes coding more difficult. I was able to manage with a sharpie, and notice no real difference with or without coding. I had coded it as a 35mm Summilux Asph. The only thing I lose without coding is the focal length readout in the EXIF data, but that's really not a problem, as the signature of this lens is unmistakable between 1.2 and 2.4, which is where I use it. I've left the camera set to "on" for lens coding + IR, so when I change to a coded lens, I don't have to switch settings in the menu.

For $6 (shipped to England) you can get the Bo Coder. Bo Lorentzen is great to deal with, and a RFF member. I have it, and it works perfectly.

It's a great deal, the best investment in Leica digital that I've made.

Usually 35 mm is not much of a problem. I have some 35 mm lenses I never bothered to code, and I never noticed visible cyan shift. I always leave the coding detection on, except for lenses that go clearly wrong because of a screw in the mount.( for instance an Elmarit 28 will be read as a 90 mm lens)

Ill order one of them. looks like it should work well with the notch for lens mount. both my lenses have a screw where the coding should be. Hopefully ill manage to sort it out though

Screw in the lens mount? Use Tippex!

A dab of white paint make the screw invisible to the code-reader. I used automobile touch-up that comes in a little tube with a brush cap. It's a thick paint and bonds well to metal. I used it for the black codes too, even though it's high-gloss it works perfectly in my hand-milled troughs.
