The Adapter for Pentax K Mount To Canon EOS M Cameras from Novoflex allows you to use Pentax K mount lenses on Canon EOS M mirrorless cameras. This will provide you with a broad range of focal length and lens type options to use on your Canon mirrorless camera. This adapter has an integrated aperture control ring and can be used with all Pentax K mount lenses. This is a completely manual adapter: no electronic information passes from lens to camera, and manual focusing is required. Using the camera's aperture priority mode for exposure metering is suggested.

Q: 1. The EF Sigma 35mm 1.4 Art is loose when attached to this adapter. There is some play when handling the lens while it is attached. Is this an isolated issue or is this an issue with all EF lenses when attached to this adapter?

A: Based on our adapter and lens in the superstore, we experienced very little play, though with most items there is a degree of tolerance that is typically met before they are approved by manufacturers for sale. I'd recommend reaching out over live video-chat to see if our team can identify if your amount of play/wiggle is "acceptable".

Q: 2. will this work on the canon m50?

A: No.

Q: 7. Can I use this adapter on a Canon mark 5d iv to mount Canon RF 35mm f/1.8 IS Macro ?

A: No. You are not able to adapt RF lenses to EF cameras due to the significant difference in flange focal distance. This adapter is for the reverse (EF lenses to RF cameras).

Q: 8. Does it works on a 6D mark II?

A: No, the Canon Mount Adapter EF-EOS R, B&H # CAMAEFRF, is not compatible for use with the Canon EOS 6D Mark II DSLR camera. The Canon EOS 6D Mark II DSLR camera is, by design, already compatible for use with EF lenses, and no lens adapter is required to connect an EF lens onto the Canon EOS 6D Mark II DSLR camera. The Canon Mount Adapter EF-EOS R is designed to connect EF-mount lenses onto the RF-mount lens mount used on Canon's mirrorless digital cameras, such as the Canon EOS R Mirrorless Digital Camera and the Canon EOS RP Mirrorless Digital Camera.

Q: 9. Will EF lenses with stabilisation be able to use stabilisation when mounted to the adapter and onto a Canon EOS R5 C?

A: Yes, the Canon Mount Adapter EF-EOS R support the Canon EF lens IS wich combines with the Canon EOS R5C electronic IS.

Q: 10. What is the difference between this mount converter and the Control Ring Mount Adapter?

A: Honestly, the control ring is the only difference. The adapters function the same. The addition of the control ring adds a customizable control while using your EF lenses, so it can be aperture, ISO, or a number of other things.
