AF confirm OM adapter for Olympus E-3 E-510 E-410 E-520

'AF confirm' OM 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 f2.8 (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)

  lens 'rear protrusion' issue

?

some lens has 'prong', which might interfere with the chip.  We'll go through two steps to determine if this will be an issue:

?

step 1):

check if the 'rear protrusion' is less than 10mm from the 'lens flange';  if so, we're safe to fit the adapter with your lens;  if not, we need to do one more checking (shown below)

?

step 2):

the chip is about 24mm across when attached on the adapter, and it's right on the opposite of the 'red dot' of your adapter.   Assuming you already have an adapter, attach your lens to the adapter to see the 'initial position' and 'final position' , if either one and the distance between them overlap with the chip position, we're out of luck...    :-)  if not, we're on the go.
