Comments such as this puzzle me. Are you under the impression that the
smaller sensors convert your normal-range lenses into telephoto lenses
because of the cropped view?

No, but until FF hits 80mp, on average I'll get closer to an animal or bird
and get more pixels (and more detail on it) on it than someone with a FF
camera. Leaving off wildlife photo experts who hide in blinds all day that
is. I've seen this happen on more than once.

In your example, I doubt that m-pixel density is the most important
factor since someone with a telephoto can walk closer to the subject,
too, if the subject is willing to stay put. I'd go with lens quality
over m-pixels in this situation, and there are several excellent
telephoto lenses available that will easily outperform normal lenses for
wildlife photography.

moving closer changes the perspective.
