I am using my EF 70-200 II lens attached via adapter to my EOS R6 and EOS R6 Mark II. This is my Goto work horse of a Lens and when using on my R6's. But sometimes the lens loses focus between shots. I am a sports shooter. and when I say loses focus its in-between subjects. I may photograph a horse rider and take several shots. No issue. But then Pause waiting for next rider. then when I attempt to shoot, the lens struggles to acquire focus. But after manual focus, the lens will then acquire focus. (I lose some initial shots) I have NOT had any maintenance done on the lens. At the moment, can't afford a RF 70-200. think I need to send in for general maint? thoughts? I have rechecked all switches on lens.
