6D MkII + 24-105 f4 II sharpness problem

[Simone81]

Hi, 

recently switched from a Nikon D610 to EOS 6dMkII with a 24-105 f4 II lens.

Compared to my previous camera, I noticed that the sharpness of the photos is much much lower (before I had a 24-120 f4 Nikkor, so quite similar).
Also shooting with tripod, at ISO100 and f11, as in the attached photos. You can zoom on books to see the lack of sharpness.

Firmware updated, with the stabilizer deactivated the difference is still minimal (in the attached photos it is deactivated). I also tried to reset to factory settings.

Am i doing something wrong or it is just the camera/lens standard result?

Thanks

ISO 100, 31mm, f11, 10s. on tripod

I never noticed, because the Canon 80d only have it to film, but I can see, then I'll pass it on to you. greetings
