This is a compact remote switch with a 2.6' cable to prevent camera shake for super telephoto shots, macrophotography and bulb exposures. Handy for taking pictures of subjects that are difficult to approach, or to minimize vibration for close-ups and time exposure. The remote switch works just like a shutter button, enabling halfway or complete pressing. It also has a shutter-release lock.
