The control module is mounted on the camera's foot. Inside it is a place for four AA batteries. Using your own power supply does not burden the camera's battery, which translates into longer working time. The device can work in continuous and flash mode, and the light strength is set on a seven-point scale. The burner has been divided into two sections; left and right. Each of them can work independently. This torch is attached to the lens via rings. The set includes rings for lenses with 52mm, 55mm, 58mm, 62mm, 67mm, 72mm filter diameters. We also offer a model designed for SLRs with an ISO foot.
