When is 24-50mp not 24-50mp? When the lens won't support it

No, not the centre, the edges. If your lens won't support edges, you either put-up with second-rate images, you crop (which reduces overall resolution) or you frame images so as not to include the far edges of the lens, which also reduces total resolution. Specific area resolution is ok, provided the lens is decent in the centre, if you frame an animal in a wildlife shot using only part of the field, that part of the field will have a higher resolution than the same area done with a camera with fewer pixels. However, if the lens is poorer in the centre than other lenses, then none of the images produced may actually have 24-50mp resolution. Tragically, it seems more than a few people buying into high megapixel full-frame cameras (some of which are now relatively inexpensive now) cannot afford the lenses needed to full exploit their resolution. Those poor souls are left to soft-focus portaiture or other gauzy, pseudo-evocative images.

I am glad to know that you have discovered that not all lenses are
born equal.

This qualifies as a "tragedy?"

And I spent all that money on eBay until I found a soft-focus lens
suitable for portraiture!
