THANKS Chris. It does take some pratice and time to get good at. And some days I seem to be better than other ha ha so it's still a work in progress. Tabs on the lenses help me. It becomes a mussle memory kinda thing. Knowing where the tab should be when someone is at a certain distance for them to be sharp or where it should be when you need a scene to be sharp. I also shoot a lot at high ISO 1600-12.500 so I can be at say f/8 and 1/1000 of a second. Noting is faster than being pre focused and having my exposure pre set.
