Brass Tri Tadpole Custom Soft Release Button for Fujifilm X100s/X100 X-E2/X-E1 XPRO1 X20/X10 by Lensmate
Our beautifully designed buttons are a perfect complement to the Lensmate Fujifilm Thumbrests. Fits any shutter button with a threaded hole. We offer several unique engraved designs, some based on traditional Japanese family crests, in both aluminum and brass. 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. Of course if you prefer using your finger tip, or it just lines up better with the shutter button you might prefer the non-engraved concave brass model, though there's no reason you couldn't use the convex model as well (mushroom shape).
