'AF confirm' Pentax M42 screw mount lens to Olympus 4/3 body adapter
4th version chip
?
1) ultra smaller and slimmer -- unlike other old version 'clumsy' chips :-)
2) programmable: set aperture value / focal length / front or back focus calibration
?
* smaller/slimmer chip allows more lens to fit the adapter without 'physical operation' on the lens
** some lens/cameras combination will experience front or back focus problem... in that case, you can calibrate the focus confirmation point via the chip
what it is ?
Basically it is an emulator of Olympus 4/3 system AF lens, by attaching a 'smart' PCB chip on a conventional lens mount adapter.
what it does ?
Whenever your subject gets in focus, the AF confirm indicator will light up and and camera will beep (except in 'MF' mode, more details below) for your notice.
work for my Olympus ?
It works fully on Olympus E-300, E-330, E-400, E-410, E-500, E-510, E-3 (all current Olympus 4/3 DSLR, sorry that it does not work for all E-1's).
How to use?
1) mount the adapter (with the lens)
2) Set the camera to A (aperture priority) or M (manual) mode
3) Set the camera to the modes you want ('S-AF', 'C-AF', 'MF', 'S-AF + M', or 'C-AF + M', YES, the AF chip will work in all those modes)
4) turn on the camera, and an aperture value of f1.4 (in future, might change to other values) will show up
5) the AF confirm indicator in viewfinder will light up whenever the subject is in focus, and camera will beep (except in 'MF' mode.. which it will only light up the AF confirm indicator).
6) In general, 'AF confirm' will work for aperture value down to f/8 (indoors, if you need to go further, focus above f/8 then stop down), or f/22 (bright light, outdoors)
