I put my 70-300 Tamron lens (the cheap one) on my camera (Sony) today, the first time in an absolute age and everything was fine until I wanted to focus on something close and found that it wouldn’t.
After further investigation I’ve found that the focus ring will only move between 15ft and infinity. It’s like there is a focus lock switch but there isn’t. I’ve tried all I can think of, auto focus, manual focus and tried moving the focus ring with the lens off the camera but it still won’t go below 15ft.
Anybody any other ideas or should I start saving for a new lens?
