Related Questions and Answers

Q: 1. I'm looking for an adapter to do the opposite of this. I'd like to adapt my new Sigma L Mount lenses to a Canon EF body. Does such an adapter exist?

A: I'm sorry but that adapter does not exist, flange to sensor distance does not allow for it.

Q: 2. Does this provide aperture control on Zeiss ZE lenses?

A: Yes it does work well

Q: 3. Will this work on a sigma FP with the Sigma efs 17 - 50 F 2.8 lens?

A: The Sigma MC-21 is compatible with the Sigma 17-50mm Canon EF mount lens. However, the 17-50mm is a crop sensor lens and the Sigma FP is a full frame camera. The camera would need to be set to crop mode (lower res setting) or vignetting may occur.

Q: 4. Does this adapter have a rubber ring around the lens mount to prevent dust and moisture?

A: This adapter is not sealed.

Q: 5. Does this have the USB port for updating lens firmware (like the same-priced MC-11)?

A: This adapter does not have a USB port for firmware updates. The firmware is updated while it is attached to the camera or to the Sigma USB dock SIUSBDL, https://bhpho.to/3hzUXFz.

Q: 6. Will this adapter allow Canon EF lenses to shoot wide open at f/1.2 on L mount bodies? The Sigma MC-11 and Metabones adapters don't support f/1.2 on Sony E mount cameras, maxing out at f/1.3

A: Unfortunately, Sigma doesn’t support the use of Canon brand EF lenses on the MC-21. That being said, your results may vary when using them with the MC-21.

Q: 7. If I use a Sigma art 24-70 EF with this adapter, will the autofocus mode work while I am recording?

A: Continuous AF would not be available, but rather Single AF.

Q: 8. will this adapter work with Canon tilt-shift lenses?

A: Although Canon TS/E lenses can work, this adapter works best with Sigma EF mount lenses. Your results may vary.

Q: 9. Will the adapter work with a Leica CL?

A: As of now, the MC-21 is not compatible with Leica cameras such as the CL.

Q: 10. Hi, this is compatible with Sony FX3 and Sigma 18-35mm F/1.8 DC HSM ART CANON?

A: No, the Sigma MC-21 Mount Converter/Lens Adapter (Sigma EF-Mount Lenses to L-Mount Camera) is not compatible with Sony FX3 and the Sigma 18-35mm F/1.8 DC HSM ART for Canon EF as Sony accepts E mount lenses. You have to use the Sigma MC-11 Mount Converter/Lens Adapter (Sigma EF-Mount Lenses to Sony E) BH #SIMC11C instead.
