Extra Mattebox information

If two 4X4" filters are placed against the front of a lens wider than 5 mm they will vignette. This means that the edges of one filter will be visible in the picture. If only one filter is placed against the lens front (without rotating) it will not vignette. Therefore it is impossible to design a mattebox with two 4X4" filters for lenses wider than 5 mm.

Especially for these lenses we have designed an adapterring that makes the mattebox slide about 7 mm further over the lens. This means that the first filter slot is being sacrificed and that only one 4X4" filter can be used. In case of a rotatable filter (in 90% of all cases this is a polarizer) we have a 4.5X4.5" filter frame and matching polarizer filter available.

With the MB-350 one non-rotatable 4x4", and two non-rotatable 4x5.65" filters can be used. Or one rotatable 4.5x4.5", and two non-rotatable 4x5.65" filters can be used.

If you want to use your mattebox in this configuration you will have to order the following extra accessories in addition to a standard MB-315 MB-325 or MB-350 mattebox kit:
· A matching adaptor ring for your lens (see the accessories page).
· A 4.5X4.5" filter frame, #0310-0002. (only if a polarizer is required).
· A 4.5X4.5" polarizer filter, #0380-0001.
