Does anyone here use these with adapters for OM and other manual lenses?
I seem to recall that you have to set them to the focal length and maximum aperture of the lens that you are using them with. Is this the case and do the things actually work?
Up to now I have used the normal adapters and focused by eye.

I use one with my OM 50mm f1.8 Dave and have never had an issue with it. I set the IS to 50mm as because there's no comms between the E-3 and lens therefore the E-3 doesn't know what lens is on to set the focal length to.

No issues, and it works well on the 50mm.

Thanks John. I see that you can get them already fixed into an OM mount or on their own to glue in place. I want to try one with my OM 300mm f4.5 for which I already have the mount. I may try one of the chips on its own as I don't need the rest.

I bought one of these for my E-500 some years ago. Sort of worked but a bit of a fiddle to install. Ended up stratching he screen that was already there but although they can be seen in the VF they don't impact upon the image at all.

The latest one is better than the earlier version.

Here is a link for the PDF for instrustions on programming the Dandelion chip for Olympus (& Panasonic) http://www.peleng8.com/pic/programming_olympus_en.pdf

& also found here http://www.peleng8.com/af-chip-articles/af-chip-dandelionhttp://www.peleng8.com/af-chip-articles/af-chip-dandelion/

This is worth reading too (which might even be more helpful than the above) http://oly43club.ru/forum/index.php?showtopic=351

I got a PDF from the ebay suppliers when I got mine, but was too big (635kb) for the allowed upload, so found these sites instead.

Hope that helps.
