Over the course of the last year, I have had a Leitax mount for my 80 Lux.
I have tried (twice now) to mount a focus confirmation chip to the mount and failed. The first chip must have been dead as the Canon did not see it in any way whatsoever.
I have mounted/dismounted/remounted both chips, I tossed the first one. The second chip I just removed and cleaned the mount. At least the camera saw this chip but it thought that the contacts were dirty.
I suspect that I have somehow misaligned or just missed mounting the chip accurately.
It's a shame, I have not used this lens for anything important because I just don't want to risk it. But the lens is far superior to my 85L in many regards IMHO.
Should I buy the chip that Leitax sells and go for strike three?
