The special material properties of this series ensure maximum elasticity. The large contact surface of the wing grip forms a stable abutment for the index and middle finger of the shutter release hand and this enables particularly soft and smooth release. The ball brake enables convenient long-time exposure, as it locking function remains in place after release until the operator returns it to normal operation. The rotating end piece makes it easier to screw teh shutter release into the camera.
Special suitability: harsh enviromental conditions, camera shutter with increased release resistance, extensive series of shots wirh long exposure times, frequent changing of the shutter release.
