Okay, so you're thinking that's a "no brainer" ...
Here's the thing.
I'm shooting through the window (which I mean shooting through the glass in the window) and I'm getting AF focus just fine, but I figure I can open the window and get a couple snaps without the extra glass in the way.
So, I open the window (crank the glass out of the way) and have a clear shot to my subject, but now I can't get focus to really lock on (doesn't seem like it is responding) and I get a rather soft oof image.
I rinse & repeat this action about 4 or 5 times. Each time, I get sharper focus (AF only at this point) while shooting through the window (glass) than with the window open. Shooting subject inside the house, all AF is good there too.
The rig:
80D
100-400 II
1.4X
The environment:
70 F in the house
5 F outside
The best I can come up with is that somehow "thernal layering" is mucking things up ... or that the dual pixel is being effected (grasping at theoretical straws) by it.
I'm baffled on this one.
Any thoughts?
