Has anyone managed to get the tagotech AF/IS emulator chip working with an E-620. I bought one of these and it arrived very quickly. The AF confirm light seems to work OK as far as I can tell but I am having difficulting getting the chip into program mode.

Following the instructions on the tagotech website doesn't work. I did manage to get the chip into programming mode once and set the focal length to 400mm but I'm not sure how I did it. Now I cannot replicate the steps to set the aperture.

The website for the chip is:

If it's Russian I could ask : there was an amazing Russki site about adapted lenses on 4/3rds bodies but I can't find it now, I do remember they sold their own chips and stuff.

It came from Singapore but it looks like the ones attributed to Victor Lushnikov going by the pictures I have seen. Also the programming instructions are similar to the ones I have found on line for the "Victor" chips (but they didn't work either)

It is definitely not one of the ones from


which is possibly the site you are thinking of.

Yeah, that's the site.
No help then, never mind.
Personally I never figured out how they can possibly work right, given the limited amount of feedback from the camera...

I am using this AF confirm chip from Tago Tech (http://www.ebay.co.uk/itm/230671199585?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649) and I managed to program it using the provided programming guide (http://www.tagotech.com/pic/oly_chip_prg_new.html).

If I remember correctly the instructions were not 100% accurate but it was not difficult to figure out how to proceed.
