Guys, I have the deepest respect to every scientific theory. However, as a past scientist I know that if the theory is not backed up by practice it needs to be changed, or at least be modified.

Sorry Yakim, but in this case it isn't just theory, it is fact, which also has been proven in more than 100 years of photography. I know you noticed a difference, but basically something else must be at play. The phenomenon you noticed cannot be caused by the magnification you are using, if they are exactly the same. Same amount of light, same magnification, equals same aperture and shutterspeed, if the EV in both cases is exactly the same, as is the amount of light received per square unit. If it is not the same, which you indicated based on differing shutter speeds or apertures, something else must be affecting this, and that may actually be many things, whether the aperture isn't exactly right, whether the metering system somehow gets fooled, It just has to be something else, there is no other option.
Kind regards, Wim
