K&F Concept OS2-90 Flat Octagonal Softbox 90 cm, Quick Release, Bowens Mount

The K&F Concept OS2-90 flat octagonal softbox has a 90 cm diameter but only 38 cm depth, so it fits even a smaller studio. It opens in one move without tools, comes with two diffusers, a honeycomb grid and a carrying bag, and fits lights with a Bowens mount.

The large front gives soft, even light with a round catchlight, and the highly reflective lining keeps colour temperature stable and colours accurate. It suits portraits, interviews, live streaming, product shots and studio video.

Compatible lights include the RC 120B, RC 120D, RC 220B, RC 220D, RC 220C; the light is sold separately.

One move and it is ready

Pull the latch and the softbox opens; to fold it, pinch the clips and the ribs release. The sturdy, flexible support poles resist deformation even with frequent folding.

Slim when folded

Folded, the softbox measures 72 × 26 × 5 cm and travels in the included bag with a strap. The softbox alone weighs 756 g.

Features

• waterproof, dustproof, light-absorbing fabric
• sturdy, flexible support poles that resist deformation
• highly reflective lining for stable colour temperature
• inner and outer diffuser plus honeycomb grid – combine as needed
• Bowens mount for speedlites, monolights and continuous LED lights

Diffusers and grid

The two diffusers remove hot spots and give smooth transitions into shadow – the inner diffuser alone is slightly harder, both together the softest. The honeycomb grid limits spill onto the background and increases contrast, so the softbox works for both soft and more dramatic lighting.
