The Fujifilm X-Pro1 Ergonomic Extension Kit is an accessory kit containing a thumb rest and a soft shutter release.
The thumb rest attaches to your camera via the hot shoe and utilizes silicone rubber inserts to dampen vibrations and provide stable, protected contact with the camera. This grip provides a more ergonomic structure to the camera, allowing for greater one-handed operation as well as more balance and less grip pressure required when shooting. The 22° beveled rest also offers more protection to the exposure compensation dial, reducing the chance of accidentally changing its position.
The soft shutter release is a simple design that permits easier releasing of the shutter release button thus avoiding unnecessary camera shake. This button screws into the cable release socket of your camera and creates an extended, soft release button.
