If you use a camera sliding system like the Vocas USBP-15MKII (0350-2200). We
recommend to use these matte boxes as clip-on or top bars setup. This way you can quickly
change from handheld to tripod or other setups.
If the matte box is used on a rail support, we strongly recommend using the flexible adapter
ring kit. This is a soft flexible step-down ring.
To prevent light from entering from the rear side of the matte box (and reflecting via the filter
in front of the lens), the hole in the flexible ring must match the front diameter of the used
lens. Therefore the flexible ring can stretch to accommodate most lens diameters.
For extra reduction of flare, the patented eyebrows are added in the MB-436. These internal
French flags can be adjusted to the zoom position of t
he 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.
When not using a 3rd filter in the hood compartment, it is recommended to lock the filter lock
into the retracted position to avoid possible vignetting.
This is done by pulling the knob outward as far as it will go and then twisting counter
clockwise.
