Practical, flexible arm with clips at either end to enable small objects, such as a diffuser to be held static in front of the lens during close-up photography. The other end can be attached to a firm surface, such as a tabletop.
The SW-C1 can also be attached to the guide groove of the Attachment Ring SX-1. For example an additional purpose might be to use two SW-C1 units to support a ruler for a scale reference during close-up photography.
The SW-C1 cannot support Speedlight units or cameras.
