but if my glass is behaving erratically even on a sunny day with properly aligned contrasty object? Did some tests on tripod- when I use manual de-focusing with test chart it still has no clue which way to move- all my other DA/FA glass hesitate a fraction and then drive focus to appropriate direction- but not this one
And BTW I have experienced moments when clamp is OFF (ie AF mode) that if I try to rotate the focus ring it refuses to change focus- but it ought to be a quick-shift one?
OK, too many questions and too few solutions...
Best and happy shooting and sharing Your experience to everyone, JR
