Maybe i overreacted, for which i appologize. But another thing, on the 5D mark IV in the first menu (shoot1) tab1 there is an option "Lens abberation correction", when you select this option you can select different kind of things to enhance the lens (in my case a canon lens 24-105mm f/4 L IS USM) you can select 

Peripheral illum correction
Distortion correction
Digital Lens Optimizer
Chromatic abberation correction
Diffraction correction

Each of this options you can set to ON or OFF. Diffraction was ON

Thanks Ko Jonus.

My intention is not to bother you, but it is not common to shoot at f/20 nowadays. This is why I'm curious about it.

With f/20 you will surpass the difraction limited aperture on any existing full frame DSLR. Diffraction impact negatively the final result of the image taken. It will lower the sharpness and contrast, the optical effect is similar, but less strong, to what you can get from a softfocus lens.

I any case I like the result.

I am not the kind ot guy who tells nonsense about how his pictures are taken and with what equipment i take them with. I Shot this one  with no flashes and a 20 sec shutter time, in a sparse lit room. Shot it with my 5D mark iV and Canon EF 24-105mm f/4 L IS USM on a tripod the specs are as i stated;

shuttertime 20 secs

aperture f/20

focal length 65mm

¿f/20 on a 5D mark IV? You should get strong diffraction something like shooting with a soft focus lens.
