Please, I am searching for a adaptator for my 4/3 leica lens for using on a leica R8 (I want to purchase) but I don,t find it. I only find leica R lens adaptator to 4/3 bodies.
Anybody knows

I doubt such a beast exists - and even if it did, would you really want to use your lens solely for extreme close-ups with most likely lousy corner performance and possibly incomplete frame coverage?

I have got a leica 14-150 mm with 4/3 mount and I wanted to use this lens with a R8 (this way I avoid to buy another lens, expensive)

The R8's flange focal distance is much longer than a Four-Thirds camera and its frame size about four times the area. You're pretty much on a hiding to nothing.

I think using the 014150 on the Leica body would be like working with a 20 to 25mm extension tube ....I cannot find my link to be more exact.
Unfortunately you are working the 'wrong' way in trying to use a lens designed for a shorter lensmount distance on a camera with a greater L/M distance. If the Leica would permit you to put the lens some 20mm inside its body it might focus. Probably the crunch point is "does the 014150 have aperture and focusing rings". My 014140 just has manual zoom.
The only photo I can find is a thumbnail and I can see 'something' but not sure what it is :-)
To get normal focus the lens would have to go inside the R8 body and make access to those controls difficult... an interesting and not a cheap engineering exercise ... cheaper to buy a lense I think.
Since I cannot see an R8 in the list of leica digitals I assume it is a 35mm 'full frame' camera so coverage would be problematical too as others have suggested.

Found my link and Leica R is 47mm while 4/3 is 37mm so not as bad as I thought ... just ten mm into the R8's body . Vignetting might not be so bad too. But the 014150 is designed to cover 17mm across compared with 36mm across for the camera .. a 4:3 coverage rather than 3:2. Everything mitigating against success I think ... Sorry :-)
A simple check for coverage would be to project an image onto a piece of paper marked with a 36x24mm rectangle.

Thanks friends. I realized that I am looking for a impossible device. I didn,t know this tecnical dates.
I will look for a leica lens.
thank you at all

Re "just 10mm": 1mm could lose infinity focus!
