Hi
Have had this combo for a while now but recently noticed the lens will not focus when at maximum focal length 400. I have to reduce to approx 300 then the lens will focus quickly then when moving back to 400 it will focus.
I did get a message a couple of weeks back saying camera and lens not communicating ( clean the contacts). This I did but the issue has persisted
Wondering if anyone has come across this, surely not normal as I would have thought I would have noticed it earlier.
