Meike has just released an unique and intriguing adapter that lets you use EF (or EF-S) lenses on more current Canon cameras with an RF attachment. Furthermore, you receive a unique characteristic of RF lenses: The Meike MK-EFTR-B adapter comes with a control ring integrated right in.
The control ring on Canon’s RF lens system, which is the successor of the formidable EF lens mount, is a very useful feature. This additional ring on the lens may be assigned to whatever parameter you like, including aperture, shutter speed, and ISO.
Meike has released a new adapter that not only converts older EF lenses to the Canon RF mount, but also includes the control ring indicated above. This makes appropriate use of the extra space required by the adapter to bridge the EF glass’s larger flange distance.
Meike MK-EFTR-B Control Ring Mount Adapter
This new adaptor, like the Meike MK-EFTR-C adapter, which can handle circular filters or even a variable ND filter, adds some utility to the mix rather than merely adjusting lens mounts.
Electronic connections for communication between the lens and the camera are provided by the Meike MK-EFTR-B Control Ring Adapter. The following are some of the features:
- control ring function that is customized
- IS image stabilization is supported.
- autofocus EXIF data transmission support
- Upgrade to Type-C firmware
SUS304 stainless steel is used to create the Meike control ring adapter. Aluminum is used to make the control ring. Dust and water resistance is provided via a rubber ring.
The entire device measures 74.4 x 24 mm and weighs only 130 grams. This new adaptor costs $110, according to Meike.
Of course, you must still determine whether you require a control ring or a drop-in filter holder for your workflow. Of course, a hybrid of the two would be ideal, but I doubt that the restricted space will allow for such an adaptor.
