Vocas 0420-0500 (0420_0500, 0420/0500, 04200500, 0420-0500) Flexible Adapter Ring for MB-430
The Flexible Adapter Ring for MB-430 from Vocas features a soft fabric cuff, which can be stretched around any lens with a diameter of 134mm or less. The ring fits into the rear clamp on a MB-430 matte box, and the drawstring helps prevent stray light from entering the lens. This ring can be used with lenses that extend while zooming, because the cuff will move with the lens.
