>>4174065>AF-D lenses make a D850 have the same image quality of a D700Nonsense.
On the D850 you could shoot medium RAW files (25mp) and have excellent sharpness with basically all AF-D lenses, even something like the 50mm 1.8D wide open is not too bad.
Put that same lens on a D700, and you're getting less than 10 MP before it turns to a mushy mess.
AF-D lens sharpness is fine.
It's more of the loss of contrast, flare/ghost issues, heptagonal bokeh, uncorrectable distortion (in non-D AF lenses), chromatic aberration, focus issues etc., that you have to look out for versus newer AF-S lenses.
Always get the D version, use a lens hood, and have a body with AF fine-tuning, and you'll be fine.
