New matte boxes the MB-435 & MB-455
The MB-450 has been updated to the MB-455 and the MB-430 has been updated to the MB-435. These new matte boxes now both have the same maximum lens diameter of 143 mm, an industry standard. For clip-on use these matte boxes will work with 143 mm lenses right out of the box. By using step down adapter rings these matte boxes can be used on smaller lenses as well.
A variety of accessories are available such as side flags, 15mm (Studio and Lightweight) brackets, 19mm brackets and swing-away options.
Thanks to these updates many bellows and step down rings can be used regardless whether these are from Vocas or other manufacturers.
