i have one of the first 50-135 in europe,and it is working perfect still since the first day.

I have the idea that the first production run is absolute ok,than after the first run,it began to be a little problem.

But the new motordrive is absolute without problems since it will be switch into the service lenses.
So,i think it is the first run of new (old) quality.
Wait till September,you will see and hear more

Best regards
