Lolumina Mini Soft-Release Button-Complete Kit (Black) This Lolumina Mini stick-on soft release button 10mm kit is available in Black, Gold, Green, Red, Silver, see our other listings. Fits any shutter button that does not have a threaded mount. Works well on the Fujifilm X-T1 with the Lensmate X-T1 Thumbrest. Most users of the domed soft release button find that the new position places the first joint of the shutter finger over the shutter button when the hand is relaxed, enabling a softer shutter release and allowing lower shutter speeds without shake. Complete Kit: Includes Soft-Release Button And Mounting Base
