Install Auto Focus Confirm Chip to my Opteka 500 f8 telephoto lens and shoot with handheld. It works perfect with the result of the images and still have to learn to program the data chip. All these bird's shots were taken with my Olympus E-620. The AF confirm indicator in the viewfinder lights up when something gets into focus. When the AF confirm indicator blinks, it means the focus point is too close or beyond range. AF confirm indicator will light up with a "beep" sound (only on the first time it gets focus). You need to 'half press' and hold the shutter release button while performing the focusing. Hopefully I can program all my manual lens to work with AF confirm chips and no more difficulties in getting focus.
