How do I attach the Lensmate adapter to the Powershot A650?
You need to remove the silver trim ring from the cameras lens barrel by pushing the silver release button located next to the trim ring on the front of the camera. This exposes the bayonet mount. Find the index mark located on the outside of the adapter near the end that attaches to the camera. Line this mark up with the corresponding index mark on the camera front located just above the silver release button. Gently push the adapter onto the camera, then rotate it clockwise until it locks into place..
