Hmmm, not sure what that means. One would pretty much expect that any camera getting close to 50 years old would need a good CLA before use. The F series are wonderful little cameras with razor sharp lenses. You can't go wrong there if you are looking for half frame.
I don't disagree but what I was pointing out is that the Yashica's are 25 years or so younger, so don't need a CLA unless you're very unlucky. Mine didn't, it worked perfectly.
