Hello Awaldram, the focusring on my 50-135 feels well damped. But it Always have and the focus is very accurat but a bit slow like all reviews are saying. It takes about 2 seconds for the focus to travel back and forth against a blank object. Are you saying my lens is about to fail? Cheers and happy hollidays

No but I would say your seals are putting additional load on the piezo motor so in the scheme of things is more likely to fail than one that doesn't.

if your saying 2sec back and forth that is quick , I'm talking 1.5 sec each way roughly.

Do you ever find it fails to do the double take and achieve lock.?

Having said that I don't think you have a case unless it does fail.

happy Holidays

p.s. if your not seeing issues I'd not worry
