Vizelex ND Throttle Fusion Smart AF Cine Edition Lens Adapter - Compatible with Canon EF/EF-S Lens to Canon RF Mount Cameras with Auto Functions, Vari-ND Filter (2 to 8 Stops) & Positive-Lock EF Mount

Designed specifically with the Canon Cine lenses in mind (works with all Canon EF mount lenses!), the Cine Edition adapters from Fotodiox were built to mimic the breech-lock cine style cameras that those lenses are designed for. The biggest advantage of using an adapter with a breech-lock mounting mechanism is that they have a very solid connection, reduce friction and wear & tear on the lens.

The addition of the removeable tripod foot on the adapter itself, eliminates possible flex or bobble from the camera mount side of the adapter when using a gear drive (manual follow focus or focus motors). The rotating collar ramp is fairly shallow so you get a great mechanical advantage: by the time you feel a strong resistance to further rotation, the lens is well and truly snugged down against its flange. The camera simply dangles off the back of the adapter, and its mount isn’t subject to any more stress than the weight of the camera’s body itself.

**Note:**
The CINE mount rotates until snug with no defined stopping point or locking catch. Turn until tight, loosen by turning the opposite way. Make sure to tighten sufficiently but do not turn too far or it will fall off as this is how PL-style mounts function.

Sometimes you need more than a simple adapter to mount a lens onto a camera - you need real power. The FUSION technology built into the adapter enables electronic communication, powered by your camera, between mixed lens and camera platforms enabling auto focus, aperture control, image stabilization, EXIF and aperture data to be transmitted to and controlled by the camera and more. Manual lenses can still be used by turning off electronic communication with the Function button.

**Note:**
Not all Canon EF lenses will perform the same depending on Lens firmware, focusing motors, age of lens and manufacturer. Test lenses before critical shoots.

The Vizelex ND Throttle is well known for having a built-in variable neutral density filter that offers 1 to 8 stops of light reduction. This concept in adapters has been praised by film makers and now Fotodiox has optimized the adapter for that same crowd. The new Cine Edition ND Throttle now feature a geared rotating ring for more precise ND selections and can be used with follow focus accessories. This version of the ND Throttle also features a locking thumbscrew on the filter ring to ensure that it is not knocked out of place during shooting or while changing lenses so that every shot will match where it matters in terms of light transmission. These small change makes the Vizelex Cine Edition ND Throttle a versatile tool for any video shooter.

The Vizelex ND Throttle reduces light transmission by one stop when at its 'Min' position. The adapter helps maintain shallow depth of field in bright conditions while eliminating the tedious process of changing filters every time the exposure changes. With the filter positioned in the rear, image quality is better than if the same filter were mounted on the front of a lens. The variable ND filter is made from optical polycarbonate (CR39) for clarity and durability.
