EOS R photos are blurry even at high Aperture

Problem with my EOS R. Manual mode - You can see all the Camera setting in the below image. Camera was on a tripod . However, the text at the top of the black box is blurred. Focus was on Large Zone AF: Horizontal. Evaluative Metering. Kindly let me know if any settings need to be checked.

Same goes for all my other pics, no matter how high the Aperture is set, only some parts are in focus.

Does this happen if you are photographing a subject straight on instead of at an angle?

Did you check the lens surfaces for anything like a smudge?

Does it happen with a different lens?

Hi Rammy and welcome:

How far away was your camera from the closest bottom of the black box when you took the shot please?
Also what lens were you using?

I suspect this is a depth of field issue. Given you were using large zone focus, I suspect your camera focused too far behind the top letting for it to be included. This is because the camera is obliquely placed both horizontally and vertically relative to the whole group. Can I suggest using manual focus, with the same settings and making the lettering at the top sharp, and see how the rest of the items come out.
If that does not work at the same distance, move back a bit and try again - be prepared to crop if necessary.

As an aside, if this is for advertising, you might need a box without the blemishes on the word Mario at the bottom of the box.

I suggest you change the AF area to a single AF point, either 1-point AF or Spot AF, then position the AF point where you want the focus to be. Depending on the distance from the subject, the lens and the aperture you may not have enough depth of field.

For example with the 100mm lens and f/8 on your EOS R. At a distance of 50cm the depth of field is 1cm, some of the depth is behind the point of focus and a little in front. Stopping down to f/16 on the lens then you get 2cm of depth of field at the same 50cm distance from the subject. The subject distance is measured from the sensor not the end of the lens. There is a small circle with a line through it on the top of the camera just in front of and to the left of the on/off switch.

I thought about a DoF issue, but it looks like portions closer to and further from the lens than the blurry part are sharp., although the skewed arrangement does make it hard to be sure.
