Upload & Sell: Off
hm.. i am not an expert, but there are different brands. best is, you ask the seller, which chip is used. they can strongly differ.
some chips can be set with respect to focal length, to aperture, they can have a focus calibration, an autofocus mode, etc....
check the internet for Dandelion, that is a such a modern chip. i got my ones from tagotech and from somebody in russia.
