114 to 85 mm Step-Down Ring
The Movcam 114 to 85 mm Step-Down Ring adapts a 114 mm threaded matte box so it accepts an 85 mm lens. It is built for camera operators who own a 114 mm matte box and want to use smaller-diameter lenses without buying a new matte box. The aluminium construction keeps the joint rigid while adding little mass to the rig.
Replacing loose adapter rings
This ring replaces makeshift step-down rings or tape-based workarounds that can shift during a take. The precision threads lock the lens firmly to the matte box rear adapter, eliminating wobble that would ruin a shot. The upgrade is worth it whenever a production moves between 85 mm and larger front diameters on the same matte box.
Handles 85 mm lenses on 114 mm matte boxes
The ring comfortably handles any 85 mm front-thread lens mounted on a 114 mm threaded matte box, maintaining light sealing and filter alignment. It runs out when the lens front thread differs from 85 mm or when the matte box uses a non-threaded clamp system, requiring a different adapter.

Questions about this item
What thread sizes does this step-down ring connect?
It adapts a 114 mm threaded matte box to accept an 85 mm lens, bridging the two diameters with a single ring.
How do you attach the ring to the matte box, and what is the common mistake?
Screw the ring onto the rear adapter of the 114 mm threaded matte box until snug; the mistake is cross-threading the fine pitch by forcing it instead of starting it by hand.
When should the ring be replaced or serviced?
Replace it if the threads show wear, the fit becomes loose, or the ring no longer sits flush against the matte box adapter.
