The Chrosziel MB 415 Compact Wide Angle Mattebox for 15 mm support systems features a dual filter stage for filters up to 5.65 x 5.65" and 5 x 6" in vertical orientation. Both filters can be shifted and locked in any vertical position, with the second filter stage rotating 360° or up to 240° (depending on the filter used).

For optimal use of the shooting angle, the first filter stage is equipped with a multi-format filter holder for 4 x 4 and 4 x 5.65" filters, while the second stage features a multi-format filter holder for 5 x 5 and 4 x 5.65" filters. Using 4 x 5.65" filters in the front stage and 5 x 5" filters in the second allows you to take full advantage of the wide angle format for any position of the rotating stage. For even more flexibility when using graduated filters, insert 5 x 6" filters in the first stage (filter holder 510-02).

A third stage is included inside the rubber bellows for round filters with a diameter of 138 mm. The MB 415 mattebox mounts on lightweight 15 mm supports and features a 114 mm ring. A folding top flag measuring 15 inches (39 cm) wide is included. Side flags (sold separately) may optionally be used. For maximum stray light reduction, use flags.
