Canon G7X macro really bad

Re: Canon G7X macro really bad

I recently upgraded from a G9 to a G7X and have been noticing it is very difficult to get a sharp macro image. I decided to do some direct comparisons and the problem is far worse than I thought. While the G9 does super sharp macro less than 1cm from the subject, with only slight softening around the edges, the G7X has to be several centimetres away and has terrible distortion everywhere except the centre of the image. I know they had to make compromises to fit such a fast lens into a small camera, but I suspect there may be something wrong with this one. Even in the centre where it is sharpest it is still far inferior to the G9.

Could someone else with a G7X take a similar photo so I can see whether there's something wrong with mine or it's just a shitty design? The photos are of a full HD laptop screen, taken as close as the autofocus can handle.

Sample G7X photo:

Sample G9 photo for comparison:

Thanks for any help!

What you are mostly seeing here is the effect of the much shallower DOF that G7x has due to it's larger sensor. The edges of the image is further away than the center and becomes out of focus. Best macro shots with the G7x is done by backcing of to 40 cm and zooming in to 100 mm FL. This will give you sharp subject with nice blured background making subject separation much better than a small sensor camera.
