Nikon AR-11 - shutter release button

The AR-11 allows users to enjoy soft and vibration-free shutter operation. The accessory can be attached to a Nikon camera by screwing it into the release socket on the camera's shutter-release button. Adoption of ebonite resin for the top surface of the AR-11 further enhances the light feel when pressing the shutter-release button. Ebonite resin creates a unique and rich texture over time that melds with the finger. It is often used in high-end fountain pens and the mouthpieces of wind instruments such as saxophones and clarinets.
