Quote:It has to be at its infinity setting... More than 10m to show 2.8, is this normal? I used 100mm before and didn't notice this. 100mm lens showed the effective aperture at macro settings only.Yes, it is normal. The longer the lens, the higher magnification it reaches at a certain distance, and the sooner you get a noticable bellows effect.
Whether or not the Nikon cameras show the right approximation with all macro lenses, I do not know, since it is unknown how the effective aperture actually is derived.
