Vocas MB-435 3 Stage 4"x5.65" Clip-On Mattebox

The Vocas MB-435 mattebox is designed as a 4"x5.65" matte box with all the unique Vocas features but at an economical price and is perfectly compatible with big lenses and the latest large sensor and 3D cameras. When the filter trays need to be rotated above standard 15mm rails it is advised to use a swing away bracket for this matte box. This will allow the height of the rails to be lowered so the filter trays can rotate freely.
