Focus and sharpness on GX10

Two photos attached have been taken with my GX10 with two lenses Sigma 35mm F1.4 DG HSM and Sigma 10-20mm 1:4-5.6 EX DC HSM. Both photos from a remote controlled tripod. I'm not really happy with overall sharpness of those setups. Does it look like there is a problem with my camera?

It appears to be back focusing. Unfortunately I believe the GX10 has no focus adjustment.

These charts are used to measure AF accuracy rather than sharpness in general.

It looks like the chart was not shot at the proper angle, so we can't draw any firm conclusions from these photos regarding the AF. It might also be a good idea to shoot these in daylight, as the GX10's AF system is not as great in low light as modern systems.

I tried to make it 45 degrees, but I didn't try very hard. Does is diametrically affect correctness of the focus test?

I was able to enable it via debug menu (but only on one out of two bodies I own!), so it works, but does not have lens memory - pretty annoying.

Thanks.
