If you crop to zoom, as any wildlife, or especially astro,

The hidden assumption here is that you are lens-limited, i.e. you are using the same lens with two different sensor sizes and then need to crop to the same framing.  This may be important for astro, but relatively little wildlife photography uses long lenses at f/stops where diffraction is significant (vs. other issues like focus, motion blur, atmospherics, etc.)
