60cm Parabolic softbox to fit Forza FM mount and Bowens mount. The Nanlite SB-MM60 parabolic softbox offers a quality diffused light that will enhance videos, photos etc. features an outer diffusion material and an optional grid to control light spill and give more direction. This softbox includes a mount specifically designed to fit the Forza FM Mount lights. As of October 2020, the Nanlite SB-FMM60 softbox also includes a Bowens S-mount adaptor ring to allow this softbox to be mounted to the larger range of Forza lights, such as the Forza 200, Forza 300 and Forza 500. To swap the Forza 60 mount ring to use the Bowens mount ring, you will need a screwdriver to remove the screws holding the mount into the softbox. The SB-FMM60 softbox also includes two outer diffuser options, a lighter "high transmission" diffuser ideal for the Forza 60, 60B and Forza 150, and a more opaque "soft" diffuser better suited to higher output lights such as the Forza 200, 300, and 500.
