Vocas MB-350 matte box - Manual (Page 4)

©Vocas Systems b.v., August 2002 4
Common directions for using this matte box:

This matte box is equipped with a patented variable matte system,
which we call “Eyebrows”. For reducing of flair these eyebrows can be
adjusted to the focal length of the lens by pulling out the “eyebrow lock
knob” and rotating the “eyebrow rotation knob”.

This matte box can be used as a clip-on matte box, although we
recommend using this matte box on 15mm lightweight rails. To use this
matte box on rails a barsadapter is required. Order #: 0360-0100.
 For even better flair reduction a “Matte” or “Mask” can be placed In the
front side of the hood. This matte box comes standard with two mattes
(1 pc. 4:3 and 1 pc. in 16:9 aspect ratio) which can be used on a
standard lens (for example Canon or Fujinon 16X lens) without
vignetting.
For other focal lengths a 8 pc. kit is available, order #0380-0200.

Th
e mask described above can also be replaced by a 4”X5.65” filter.
This provides the possibility to use 4 filters in this matte box.
Hint: since these masks are exactly the same size as an 4”X5.65”
(Panavison) filter, they can also be used in every other matte box with
4”X5.65” horizontal positioned filter frame.
 To remove the mask, pull the “matte release knob” outwards.
 For maximum flair reduction a “Side flag kit” is also available.
Order #: 0340-0002.
