Common directions for using these matteboxes:
These matteboxes can be attached to the camera in two ways:
1. clip-on:
For maximum lightweight and economical operation the mattebox
attaches directly to the front lens of the camera. Either with or without a
wide angle converter. The internal rear end diameter of these matteboxes
is 105mm, there are step-down adapter rings available for most camera’s.
2. On a 15mm rail support.
This support also attaches your mattebox to the base of your camera, and
is fully compatible with the industry’s 15mm Arri lightweight support
standard. Accessories (such as follow focuses) from other brands will fit
on this support.
If the mattebox is used on a rail support, we most strongly recommend using the
flexible adapter ring kit. This is a soft donut shaped step-down ring.
To prevent light from entering from the rear side of the mattebox (and reflecting via
the filter in front of the lens), the hole in the rubber donut ring must match the front
diameter of used the lens. Therefore the rubber donut rings are supplied in various
diameters. This ring can handle lenses up to 95mm in front outside diameter.
For extra reduction of flare, the patented Eyebrows are added in the MB-250.
These internal French flags can be adjusted to the zoom position of the lens by
rotating the “eyebrow adjustment knobs”.
Caution: Not all viewfinders, LCD screens, and monitors show 100% of the
captured image. Therefore, if the eyebrows are adjusted with the help of the LCD
screen, it might be possible that the eyebrows come into picture.
The accessory shoe of the MB-210 can be used to attach a optional French flag, a
camera light or a microphone holder.
When using a polariser or star filters the first filter frame (the one which is the
nearest to the camera) can be rotated.
These matteboxes also work in combination with most Century Precision wide-
angle adapters.
