I’ll have a closer look when I have more time Mike.
No isues such as that Mike. Missed focus is rare.
1) It hasn’t grabbed anything. Theres enough contrast that it should. Dont have the menu #s handy, but what do you have af priority set to in custom functions? Theres only personal preference, no right/wrong. Mine is set to prevent shutter release on the first frame.
2) Looks like the reel cover is outside your dof. The wall seems fine at these dimensions. Could be a back/front focus (which you can adjust) however I didnt need to do that on any of my llenses. Were you possibly inside your lenses MFD?
3) Personal preference but I rarely use single with assist. When shooting wildlife (especialy birds) I use single point only.
feel free to message or email me as well.
