Eben with dedicated macro lenses? I thought-  but never looked into it - macros are abd choice for landscape photography becasue they are less good at âˆž?

Before IF lenses, macro lenses had the bellows effect. The further you push the lens out (the bigger the magnification), the more impact diffraction will have. With IF lenses, things are a tad less predictable. But your Nikon body will tell you that things indeed still change the closer you get (the higher the magnification) with modern Nikon F-mount lenses (you see the max. aperture number available go down). With Canon for instance, things are not that obvious (the Canon does not adjust the max. available f-stop setting). But of course, the exact same thing happens.

 

Some macro lenses are less good at infinity, others are just great at infinity also. It depends on the designer. Some non-macro lenses can do great with extension tubes or bellows too, and some others suck when you focus closer.
