This Bird soft release button is also available in Blue, Black, Red and Brass, see our other listings. Our beautifully designed buttons are a perfect complement to the Lensmate Fujifilm Thumb Grips. The aluminum models have been color anodized, then the raised portions buffed to a high polish for a striking effect. The brass models receive a similar treatment - an overall patina is applied then the raised areas buffed to a high polish for contrast. All Lensmate soft release buttons are now equipped with an o-ring around the threaded shaft which creates friction between the soft release and shutter, preventing loss. Most users of our thumbrests find that the new position places the first joint of the shutter finger over the shutter button when the hand is relaxed. Our soft release buttons are shaped to nestle comfortably under the index finger first joint, enabling a softer shutter release and allowing lower shutter speeds without shake.
