Four screw-in brass release buttons include silicone O-rings for a secure fit. Broad compatibility covers many Fujifilm, Canon, Nikon, Hasselblad, Minolta, Rollei, Olympus and Sony bodies.
More precise shutter activation – with a concave metal surface
Concave profile guides the fingertip to the centre of the button, improving contact and reducing slippage. Metal construction adds inertia so the press feels steady rather than jittery.
Improved fingertip placement reduces inadvertent camera movement, helping achieve sharper handheld exposures and lowering fatigue during long shoots.
Works across many cameras – thanks to a screw-in fit and silicone rings
Threaded design screws into standard shutter button threads while silicone O-rings lock the button to the camera top, preventing rotation and loosening. The pack contains four buttons for spares or quick swaps.
Wide model compatibility and included spares mean easy fitting on film and digital bodies, with secure attachment for extended use.
Durability and reassuring weight – with 100% high-quality brass construction
Made from high-quality brass described by the maker as pure copper material, the metal resists deformation better than aluminium alloys and retains tactile integrity. Metal finish and mass deliver a solid feel.
Robust construction promises long service life and a premium feel that inspires confidence when framing and releasing the shutter.
