Hi,
I own some of the above chips mounted on various adapters (Eos? M42, Fd-Eos, Eos-Yashica) but I had never tried to program them to set aperture, focal length etc.
Some days ago I tried to programm following the instructionI I found on the site of the inventor (?), which is a Russian site, but also those found in other sites.
The result is always the same: I can not do anything!
Would someonecan give me some advice about programming this chip ?
The chip works anyway even if the lens data is not set ? I think the answer is yes but I would like to have a confimration by those who use these devices.
Thanks in advance to everyone.
Paolo
PS. I use it on Canon EOS 450D
