Meanwhile after testing the peleng8-adapter with dandelion chip here is the depressive result:
every time when changing lens one had to bend inwards the lens-locker-blade.
After a certain time this blade will break, which occurred this year. i didnt use it excessively. just to test at home. Sent back now.
Having now three adapter-versions here are the dimensions(thickness) of all three blades:
0.22mm Noname with EMF-chip
0.4mm Peleng8 with Dandelion-chip
0.7mm not chipped yet K+F Concept by Keithfaith dot com(on FB)
maybe i already opened a thread about the adapter-findings for C/Y-EOS.
K+F Concept has the best of the affordable adapters(i think it cannot be made better) but i dont know the expensive ones which also have no chip.
But i had optixpcb high-precision with their chip (has 3-lens-option) and lens-locker is terrible. and lens wobbly. signal get lost. just sent it back to get money-back.
K+F Concept goes PAST infinity so also badly or deadjusted lens can surely see infinity. maybe there is a solution to set infinity exactly for each lens. using shim.
Also on this adapter one must adjust the blade from time to time-bending inwards. it depend the situation on the lens. some slots are worn out.
here are most sophisticated tips about Contax/Yashica-EOS-adapters:
here one will learn how to adjust certain adapters for best fitting.
K+F Concept-adapter has all the options for this procedures.
its holding the lenses perfectly, almost no play, base for properly working chip.
Have now also found the right adapter.
Optikpcb with its easy programming and 3-lens-option would have been perfect but has i a big disadvantage: its flat wheras tagotech-chip is mounted on a piece of stairs-dont know the right word-here you can see it: the curved black plastic right from the chip(btw: the mounting-instructions are far from clear-i am about to get them hopefully) i have a second identical zeiss-lenses with the noname-adapter for comparison.
