The SM2CEFM2 easily secures a Ø2" lens tube and lens to an EF-Mount-compatible Canon camera. Lens and lens tube are sold separately. Canon cameras are not available from Thorlabs.

Features

Female EF-Mount Connects to Canon Lens
Male EF-Mount Connects to Canon Camera
External SM2 (2.035"-40) Threading for Compatibility with Ø2" Lens Tubes and Components

Thorlabs' EF-Mount Adapter Rings allow for easy integration of Canon EF-Mount lenses and cameras into experimental setups using Thorlabs' optomechanical components. The SM2CEFM adapter features female EF-Mounting, making it ideal for integrating Canon EF-mount-compatible lenses into Thorlabs cage systems and DIY Cerna setups. The SM2CEFM2 adapter features male EF-Mounting, giving the option to combine Canon EF-mount-compatible cameras with Thorlabs optics, as shown in the image below. On the side opposite of the EF-mounting hardware, both adapters feature SM2 (2.035"-40) external threading, and thus are directly compatible with Thorlabs' internally SM2-threaded components, such as our Ø2" lens tubes.

Now there are many new camera lens came out with new mounts. For example, EF-M mount for Canon, which is very different from the EF mount. I am wondering if there are plans to include those lens mounts with SM system? Thank you

Thank you for contacting Thorlabs. While we do not currently have an adapter for the EF-M type mount for Canon lenses/cameras, I have posted this idea to our internal engineering forum for future consideration. I have also reached out to you directly regarding this.
