Sony a6300 focussing

Hi all. I have a request.
My wife has a Sony A6300. She has a Sony Macro lens. She's having trouble focussing this.
I have the manual and am investigating.
However, i am stuck on a definition. I will try to explain:
When you point at what you want to shoot, an area of the screen pixellates, sort of. It looks like if you were watching the Weather Channel when they overlay rain over an area.
I've been told that this represents an area that the lens can't resolve, and this makes sense to me.
What I would appreciate is someone telling me what terms in the manual might describe this so that I can go to that section and try to fix this. Thank you.

I don’t own a Sony camera but my guess is this is an area of either under or overexposure. If I’m right I’m certain this can be shut off.

It sounds like she might be trying to focus too close but since I don't shoot Sony, I'll let a Sony shooter respond... I assume she is manually focussing? Autofocus doesn't work so well shooting macro.

that makes sense. What term/s would deal with this so i can go to the right section of the manual. Exposure? Focus?

Zebra stripes is the term for the over exposure warning.
Also ck out focus peaking. Both can be turned on/off.

If the pixels (green) are square and separated this normally indicated that the lens is in focus. The depth of field (area in focus) is very shallow especially at low f-stops (f-2.8, 4, ...) when the lens is fully extended at a 1:1 setting. Moving the camera forward or backward out of focus occurs. Higher f-stops (f-16, 22) give a greater depth of field but is still shallow. Put on a tripod, extend the lens and take a photograph when the "pixels" appear and see if the picture is in focus.
Also check the manual for focus peaking.

Great. Thank you all. I had navigated to Focus but not to what you all have described. She's in hospital til next Thursday at least so I will now get busy trying to solve this for her so she's got something to play with when she gets back.

Zebra stripes is what it is. I listened to the narrative but didn't wholly understand. I'll run through it again. Thank you.

Get Gary Freidman's book on the a6400. https://www.friedmanarchives.com/sony-books/

I use Zebra Stripes on all my Sony cameras, but pay more attention to the Histogram. If the stripes bother you, turn them off and just use the Histogram. I generally prefer to expose to the right, others may disagree.
