But frustratingly, it allows movement beyond that setting. To try and ensure it stayed on infinity for this week’s solar eclipse I used some blu-tac to keep it from moving.Sadly it moved slightly unknown to me resulting in a couple of shots being spoilt. This is one of my successful ones. Has anyone any suggestions on how to prevent it happening again? Why doesn’t the ring stop at infinity?</blockquote>
