Hi there

 

My first post on this forum and relatively new to leica, so bear with me.

I hva recently purchased one of these lenses and I need it converted to M mount by soneone in europe as I live in France. Any one has any recommendation please?

 

Thanks

Welcome to the forum.

 

If you have a M240, you only need an adapter to try out the lens. EVF suffices.

Does not work, Jan. The Canon 50mm 0.95 does not have a Leica (or Canon) screw mount. It uses an external bayonet mount, and while there is a Canon-made adapter to C mount (cine), when stacking the adapters it puts the lens too farm from the sensor.

 

Here is a picture taken without with the lens and adapters in question focused upon infinity.

 

babaky I wish you good luck with the conversion! I have had four Canon f/0.95 lenses. The first I used on the excellent Canon 7, the next three went in for conversion. Only one, the last one which I kept works on any of the Leica M cameras. It's a keeper, but overall image contrast is lower than a Leica lens.

 

Last thing - when the proper conversion has been made, releasing the lens from the M camera requires a little screwdriver, or anything to slip under the edge of the lens over the lens-release button because the lens covers the button.

Pico, you sent 3 lenses into the conversion. Only one was successful.

What went wrong with the other 2?

 

What means conversion in this case? Does the TV version have a rangefinder mechanism?

I don't understand, why the throats of the mounts are chosen so narrow. The M mount is of 1950, but that of the A7 (of 2012) is not very much wider.

When I had Ken Ruth do my conversion in the 1990s, I remember him telling me that he needed to install a "pusher" mechanism which would mate with the focusing cam of my M4, it required him to actually drill a hole into the perimeter of the glass and insert a small metal rod. He did a magnificent job...but I learned over the next year that the lens and I just didn't work well together...it was too big and significantly obscured the field of the viewfinder.

The two failures did not focus accurately. Each used a different approach to conversion. Sorry I cannot comment upon the TV version because I've never had one. spydrxx's answer is helpful.
