Can Leica S007 be adapted to M lenses?

I really want to use my M system lens on the S body. Is there any adapter ring?

The Leica Q3 is available for pre-order at B&H Photo Video and Adorama

No, you would only be able to take photographs (with longer M lenses) at very close range.  Do you know about camera mount register distances?

Your best bet is the SL system. That is the closest equivalent. There are many adapters you can buy, including from Leica and Voigtlander. It is impossible with the S because of the mirror. As you might have noticed, when you focus a lens closer, the elements move further away from the camera. So if you think about the thickness of the M body compared to the S body, you can see that you are pushing the lens further away from the sensor. That is effectively making it focus closer and closer. The distance from the lens mount to the sensor/film is called the flange to focal point distance.  As a rule, if you want to be able to focus to infinity, you can only adapt lenses made for cameras with a flange to focal point distance that is larger than the camera you want to use it on. Modern mirrorless cameras like the SL do not need to fit a mirror in between the lens and the camera, so they have a small flange to focal point distance. This is why you can use all kinds of old lenses on the SL, GFX or Sony A series cameras. But the S was designed as a medium format SLR with a large mirror, so the only lenses that will work on it are its own or lenses made for even larger systems, like the Hasselblad V, Pentax 6x7, Contax 645 and so on.

Besides the image circle of the M lenses most probably wouldn't come close to covering the S sensor, so what's the point?

Quite a few seem OK (some vignetting) on 33x44 sensors....

Most lenses have a sweet spot. With the S 30x45 sensor, I would expect the M lenses to be soft at the edges besides vignetting. Plus, the big bonus of the S cameras is the S lenses that have a distinctive look.
