R mount

hi, I just bought a Leica m6 and I wonder if it’s possible to use elmarit 28mm R by using an adaptor. And if yes are there issues with the light meter?

thank you

You could fit an R lens to an M body but remember you have no way to focus apart from guessing the distance.

Light meter will work fine. It just reads whatever light falls on the shutter curtain, regardless of source. The R lenses by default, just like M lenses, are stopped down to the shooting aperture, unless mounted on an R body, where a lever holds them open until the instant of exposure.

As James says, an R lens will have no connection to move the camera's rangefinder, thus you will have to estimate (or measure with a ruler) the distance from the camera to the subject, and set that on the lens's focus scale. "Hmmm, that subject looks about 3 meters/10 feet away."

That won't be too hard with a wide-angle like a 28mm, especially if stopped down to middle apertures (f/8) for extra depth of field. It would be extremely difficult with a longer lens (90mm, 50mm at f/2.0).

I have used both a Hasselblad Super-Wide (38mm lens) and Voigtlander's original 15mm and 25mm lenses for Leicas, which were also "guess-focus-only," with pretty good success.
