Even the "DYI" version can, and eventually will, cause compatibility issues. I had to put a strip of tape across he contacts when the chip ceased to function, as prying it loose was not an option (in this particular case). I still have a few of these chips unused and floating around in the odds-and-ends bins, but am reluctant to try over again.
Really a pity as the chip appeared as the perfect solution to a maker's dumbing-down decision.
Erik did modify my FT1 adapter so it could feed the camera through one of my own programmable chips. That solved the use of non-chipped lenses with F mount, however those are just a few of the various lenses eligible for the CX cameras. Meanwile i have this "cyber-punk" version of the FT1 with a switch on top of it
