The ML-L7 is a Remote Control that uses Bluetooth® to connect with select Nikon cameras. It allows photographers to control various camera functions on the camera as well as trigger the shutter from the remote, so you don't need to disrupt your shooting while super telephoto shooting or when using the camera on a tripod or in a remote location. The Bluetooth® word mark and logos are registered trademarks owned by Bluetooth SIG, Inc. and any use of such marks by Nikon Corporation and its Affiliates is under license.
