Very useful information in this thread. I don\'t know if I want to take this challenge on and give this chip a try or not.
A question for anyone that is using one; once you have the chip set up, can you change the aperture value in camera when in AV mode by turning the thumb wheel the same way you would with a regular lens? Or do you have to go into programming mode to change the value? I know you still have to twist the aperture control ring to actually change it, but it would be nice if you could change the in camera value as well so that exif data is accurate.

You can only affix a value to each lens. This value will not change when you
1) change the aperture on the lens manually
2) rotate the aperture wheel in Av mode.
To me, this serves to identify each lens in peripheral illumination adjustments. There are no other uses I can think of for fixing an aperture value to the lens that I can think of at this point.
