Thanks to everyone who has responded. I was hoping that someone could post a similar photo of a monitor screen at 24mm wide angle so I could visually confirm that there's nothing wrong with my camera.

From the responses so far I'm sort of convinced that the softening at the edges is normal when trying to use macro at 24mm, although I would have liked to have seen an image taken of a flat surface from someone else's G7X just to confirm it is as bad as mine. When I sent the image to the camera shop their expert said the photo should be sharper around the edges and I should send it back but she didn't have a G7X there to play with.

The other thing I wanted to check is whether my camera is focussing properly in the middle, as I suspect it is slightly out. The reason I suspect it is not focussing properly is that when I half press the shutter to focus, then move the camera slightly closer before taking the photo, the centre looks much sharper. Below are comparison shots.

As you can see the detail in the second image at the centre is much sharper.

Does this indicate there is something wrong with the autofocus on my camera? Or maybe with the G7X autofocus in general?

Thanks in advance for any more advice or similar tests with your G7X.

I thought I had a problem until I changed the focus mode to macro and single point AF AND saved the settings.

I think. It seemed to me that it would focus properly before shutter press and go OOF and lose the focus on shutter press without it.

Since then, not a problem. I do however stop it down quite a bit - f/8 is a nice sweet spot.
