This Lens Mount Adapter from Commlite allows a Canon EF or EF-S-mount lens to be used on a Leica, Panasonic, or Sigma L-mount camera. Gold-plated contact pins provide electronic communication between an attached camera and lens, enabling autofocus as well as auto exposure features, and image stabilization functions are also supported. If an attached lens is capable of generating Exif metadata, this adapter is designed to transfer that information so that it can be saved with image files generated by the combined Canon EF or EF-S-mount lens and L-mount camera.

Constructed from aluminum alloy, this adapter is durable while remaining lightweight. To help reduce stress on the camera mount when placed on a tripod, the adapter includes a tripod foot with 1/4"-20 threads. Additionally, a built-in USB port enables compatibility upgrades and updates for new functions.

Because Sigma MC-21 does not work properly with those lenses ( changing apature when taking picture - unusable for photo ) and it has the same problem with Video but it's kinda usuable ( when you hit record it changes apature by 1 EV and you have to manually go back. After stopping the record it happens again so its kinda anyoing for any kind of event filming)

A: It is our understanding that this adapter has not been tested specifically with the Samyang XP lenses. Your results may vary.

Q: 3. Will this adapter enable full frame use of the sigma 18-35? Sigma 21 adapter only allows crop sensor n lumix S5.

Q: 8. I have an EF mount manual focus lens but includes electronic contacts for focus confirmation, electronic aperture and exif data to adapt on a Fujifilm X-S10.
