It acts as a wireless shutter release capable of instantly triggering the shutter without disturbing the camera, up to a distance of approximately 16' (4.87 m) in front of the camera. It is recommended for taking pictures of subjects that are difficult to approach, or to minimize vibration for close-ups and time exposure, and it is powered by a CR-2025 3v battery (included). The ML-L3 supports the bulb exposure camera setting making it a worthwhile accessory for shooting long time exposures for low-light photography or unusual daylight effects.
