The Match Technical Thumbs Up Boop-O Soft Release is made from solid brass, because it does not bind in threads and does not break easily – unlike some metals – eliminating the possibility of Match Technical soft releases jamming or snapping off in the shutter button. A rubberized o-ring ensures a secure fit.

Please Note:

• The "long post" style soft release is designed to fit all film M cameras, the Leica M10, M9 and M8. It will not fit the Leica M-E, M (Typ 262), M/M-P (Typ 240), M Monochrom, or M Monochrom (Typ 246).
• The "short post" style soft release is designed for cameras starting with the Leica M-E and will work on all current digital M camera bodies including the M (Typ 240) and M (Typ 262). It will not fit the Leica M8, M9 or M film cameras.
