Hi, Does his adapter work with the Leica T (701)

Sigma says it does not work with any APS-C L-mount camera.

It’s a real shame. I’d love to be able to use my Zeiss Milvus 50mm on my CL. Don’t even need AF, just iris control.

Thanks Guys, I have a lot of canon glass which I would like to keep on using with the Leica T but manual focusing is poor with EFS lenses.

The Sigma MC-21 works very good with my Canon ef-lenses on the panasonic lumix s1, but no connection on my CL.

Yeah you can manually focus but won’t have aperture control.

Is "Manual Focusing " possible on the Leica CL with the Sigma MC-21 and Canon EF lens?

Or nothing is working with this adapter on the CL?

Thanks

Nothing works with the MC-21 on the CL. You get blocked by a message saying:  ‘Firmware not recognised Please update Firmware’  This means nothing, no FW update will make it work on the CL. To be able to use the MC-21 on the CL you need to put tape over the electronic contacts.

Your best bet is to use a dumb adapter, which will give you manual focus. If your lens has an aperture ring you will also have manual aperture control. If there's no aperture ring on the lens it will always operate wide open.
