The Studio Matte Box SMB-1 supports filter sizes up to 6.6" x 6.6". It is designed for use with bigger wide-angle prime lenses, as well as zooms.
The SMB-1 Tilt has an exclusive, integrated tilt module and all versions benefit from stackable filter stages, allowing quick reconfiguration.
Uniquely, both 4:3 and 2:1 ratio sunshades are available, optimized respectively for spherical and anamorphic filming.
The SMB-1 covers the full ALEXA sensor area and allows the Master Prime 12mm to be used with a 2-filter-stage, the Ultra Prime 10mm with a 1-filter stage, and the Ultra Wide Zoom UWZ 9.5-18mm with a 1-filter stage.
