I had formulated some theories about use of the S camera that may help (if not the OP, then perhaps others who've experienced performance issues).
This morning I pulled out the S(006) to put those theories to the test and ...
MY CS35/2.5 FAILED ON START UP!
Frankly, I've had so many S lens failures, I cannot recall if the 35 was one of them ... but I'm pretty sure this lens was already sent in for AF failure some time ago. I'll have to check on that. If so, then Leica's fix isn't fixing the issue ... at least earlier fixes didn't.
I wonder if anyone has experienced a lens failure while shooting, or are all AF failures on start up, or while changing lenses on a camera that is powered on?
I had read that the improved firmware addressing AF performance had increased the torque to much for the gearing ... torque especially evident on start-up (which perhaps could be made worse if a lens had sat for some time and was a bit more stiff). So, I thought maybe manually exercising the lens before AF might mitigate the stress.
I also thought that setting the lens on infinity might help since the lenses do that on start-up ... however when I manually set the 35 to infinity this AM, it went slightly past infinity which may be a sign that the gearing had become decoupled.
It's a mystery.
And a damned shame.
Here we go again ... once more into the breech.
Hi Marc, unfortunately I cannot help you with this. Thankfully this is one problem I've not had. My lenses were purchased new and probably 12 months old at the maximum. I have heard of a number of people complaining about failed motors. How old are your lenses? Did you purchase new or second hand?
