When I first started using this camera I was amazed at the autofocus speed. I have been learning the camera and have fiddled with almost all settings but now find that my autofocus has slowed down a lot and cannot remember my starting point.
I'm using AF S and single point focus right now and have tried all 3 number of focal point settings since noticing the slow down. I do not think that there has been much change in water clarity but I'm wondering if an increase in micro particles might be a cause? Any suggestions and your preferred settings will be appreciated.
I can't see any settings apart from live view that would make autofocus slower. Are you using the same lens as when you started ?
