Aluminum Construction with an attractive matte finish gives the unit greater heat dispersion efficiency and durability. The S1 features the ever popular Bowens® S-Type Mount, making it compatible with a large scope of adapter rings and modifiers such as softboxes, beauty dishes, reflectors, and grids. Allowing for firmware upgrades, the S1 is easily updatable, when new camera models are released.
