What is L mount / L bayonet?
L mount is developed jointly by Leica, Panasonic and Sigma, for full-frame mirrorless cameras. L mount cameras including: Leica SL SL2 T TL TL2 CL cameras; Panasonic Lumix S1 S1R S1H cameras; Sigma FP cameras, etc.
L mount is not simply equivalent to Leica camera (Leica M, Leica R, Leica L are different mounts), please confirm your camera mount before purchase, or consult.
Attention:
Canon STM series lenses don't work with our EOS adapters.S
TM lens (such as EF 50mm f/1.8 STM, EF 18-135 IS STM) requires to be powered to drive the motor to focus, so cannot achieve focus with manual adapters.
Function:
Manual adapter without electronic contacts, no auto-focus or aperture control.
Connect Canon EF (EOS) lens to L mount mirrorless camera.
Support focus to infinity manually.
Aperture:
Aperture cannot be adjusted with manual adapter, and will be defaulted to the largest.
Aperture can only be adjusted when your lens has a manual aperture control ring itself.
Use a zoom lens with manual adapter, set the aperture to what you want before connecting to the adapter and camera.
"Doesn't work" Problem:
If you find the camera cannot shoot with the adapter, set your camera as "release shutter without lens" to enable when using the adapter for the first time, otherwise the camera will fail to recognize the lens and the shutter may not be released.
Note:
L mount cameras are full-frame mirrorless cameras.
Adapting APS-frame lens to full-frame camera may generate vignetting, which is not the problem of the adapter. Some cameras could correct it by adjusting to APSC.
