Whether shooting in the studio or outdoors, the Vello RS-O3II Wired Remote Switch provides photographers using select Olympus cameras with a simple way to control exposures and an easy-to-use tool to create more "keepers". The device is larger and more comfortable to use than many other remote devices, with a thick, sturdy cord.
The RS-O3II is compatible with autofocusing, continuous shooting or single image capture, and long exposures. It will autofocus on 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 can be captured. The RS-O3II does not require batteries as operates using the cameras own power, making it an extremely useful tool to keep in a studio or gear bag.
