The SMDV Speedbox A90 is a twelve-sided softbox with a diameter of 90 centimeters, designed for modeling lamps up to 300 watts. This professional lighting accessory features a heat-resistant aluminum speedring and steel rods, making it suitable for high-performance studio applications. The innovative folding mechanism allows for quick setup by simply extending the rods and equally fast collapse by releasing the locking pins. Made from durable ripstop nylon to minimize wear, the interior has a silver coating for maximum light reflection. A high-quality, removable double diffusion system includes an inner diffuser that further softens the light and reduces hotspots, with both diffusers removable for different lighting effects. The dodecagon shape produces even, soft illumination, ideal for portrait, product, and advertising photography. This model is delivered without a speedring, so separate purchase of compatible mounting rings for various flash systems is required. The compact foldable design and quick readiness make this softbox particularly suitable for location work, where rapid setup and transportability are essential. The robust construction ensures reliable performance in professional studio environments with consistent light quality over extended usage periods.
