The MTF Services Ltd. B4 TO AJA CION Package simplifies mounting optional 2/3" B4 mount ENG lenses on your AJA CION camera. The package consists of a B4 to Canon EF Lens Mount Adapter, a Canon EF to AJA CION Replacement Lens Mount, and a Lens Bridge Support. The B4 TO AJA CION package uses multi layer coated optics that maintains the quality of the image from your B4 mount lens, as it enlarges the image to cover the APS-C sized sensor of your CION camera.

The package properly orients the image to be right side up in your camera so you don't have to flip the image in post or operate the camera upside down. However, to accomplish this, you must engage the 2x extender in your ENG style lens, and there is a cost of 2.5 stops of light. MTF Services recommends using an HD lens designed to cover a 2/3" sized sensor with a 2X extender to ensure full coverage.

You can use the entire package to shoot with optional B4 mount lenses on your CION camera, or use only the B4 to Canon EF mount adapter on optional cameras with a Canon EF mount and APS-C sized sensor, such as the 7D or C-100.

  • B4 2/3" to Canon EF Adapter

    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.

  • Canon EF to AJA CION Replacement Lens Mount

    Don't adapt your Canon EF lenses for use on your Cion camera, replace the camera's mount instead with the Canon EF to AJA CION Replacement Lens Mount from MTF. Services Ltd. Take advantage of the CION's replaceable mount design and convert your Cion camera from a PL Mount to a Canon EF mount using just four screws.

    The body of the adapter is made from aluminum for its balance between strength and weight, and it is anodized for scratch and corrosion resistance. The nickel-plated brass mounting surface mates with your Canon EF lenses. The replacement mount is mechanical only and does not contain any optics or electronics, which means you will need to use manual focus/iris lenses.

    For manual lenses.
    Nickel-plated brass mounting surface for wear resistant mounting.
    Black anodized interior to minimize reflections.
