The B4 2/3" to Canon EF Adapter from MTF Services Ltd enables the use of ENG style B4 2/3" lenses on cameras with the Canon EF mount. The adapter features multi layer coated optics, solid aluminum construction and a chrome plated EF mount. A lens support bridge for use with industry standard 15mm rod support systems is also included.
Note: In order to avoid vignetting, the B4 2/3" lens will need to have the 2x extender engaged and the camera's image sensor should be Super 35mm or smaller. HD lenses are recommended. Engaging the 2x extender also allows the adapter to optically correct for using your lens on a single sensor.
