Overview:JJC® LR series luxury Remote Switch is used on almost any Digital SLR & Film SLR camera that has a remote switch socket. This is a compact Remote Switch to prevent camera shake for super telephoto shots, macrophotography & bulb exposures. Handy for taking pictures of subjects that are difficult to approach, or to minimize vibration for close-ups & time exposure. The Remote Switch works just like a shutter button, enabling halfway or complete pressing. It also has a shutter-release lock. The LR controller can connect to different types of cables & can be used on different cameras. Now you do not need to buy different remote switches, and just use it on different cameras.
