Whether shooting in the studio or outdoors, the Vello RS-S1II Wired Remote Switch provides photographers using select Sony and Minolta cameras with a simple way to control exposures and create more "keepers". The device has a thick, sturdy cord and is larger and more comfortable to use than many other remote devices.
The RS-S1II is compatible with autofocusing, continuous shooting, single image capture, and long exposures. It will autofocus with a half press of the button and trigger the shutter with a full press. Also, users can press the button and slide it forward to lock it for long exposures. It can be used with cameras that feature live-view mode. Since exposures can be triggered without touching the camera, sharp, blur-free images are captured. The RS-S1II does not require batteries as it operates on the camera's power, making it an extremely useful tool to keep in your studio or gear bag.
