The remote control allows the photographer to take selfportraits or get into group shots. Used with the mirror lockup function, it can reduce the possibility of image-blurring caused by camera shake, making it particularly useful for macro or telephoto shooting.
The CR-21 cable release switch helps prevent camera shake, making it ideal when shooting long exposures. It is also possible to lock the release button.
This provides a constant electricity supply when shooting in the studio or taking pictures indoors.
It is also recommended when connecting the camera to your computer to transfer data.
