The Vocas 138 To 114mm Step Down Adapter Ring for MB-430 allows you to use your Vocas MB-430 with available lenses that feature a front barrel with an outer diameter of 114mm. The adapter ring is a sturdy plastic split ring that snugs the lens within the 138mm opening of the matte box, and prevents light leaks. You can use this adapter ring with an available Vocas 114 to 85mm step down adapter ring to mount an available Vocas MB-215 or MB-255 to available lenses with an 85mm front barrel diameter.
The adapter provides a snug fit that prevents light leaks between lens and matte box for available internal focusing lenses with a front lens barrel outer diameter of 114mm.
The split ring design makes it easy to mount the adapter on the lens, and when inserted into the matte box, the ring gently closes.
