The Profoto RFi 5' Octa Softbox is an octagonal light-shaping tool that is ideally suited to groups, portraiture, fashion work, or any field that requires the unique wrap-around qualities of an 8-sided light source. This size makes it a good choice for location work and other work where lightness and compactness are of benefit. The RFi softboxes are compatible with more than 20 different flash brands through a wide range of speedring adapters. Note: Speedring is not included.
