Default 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.


So, got any examples of people that buy the 36MP Nikon D810 or 50MP Canon 5DS
and put crap lenses on them? If not, what's your point?

An example might be something like a cheap and cheerful Nikkor 18-35 G,
which scores 24 "Perceptual Megapixels" on a D800E according to DXOMark.
The similar focal length equivalent and price $750 lens on 1/4 frame
Zuiko ED 9-18mm f4.0-5.6 rates 9 Perceptual Megapixels, and in terms of
"equivalence" is the same as an 18-36mm f8-f11 lens on FX.


For a "portrait" lens, then a Nikkor 85mm f1.8 G thoroughly and totally
annihilates the Panasonic Leica DG Nocticron 42.5mm F1.2 ASPH, yet the
Nikkor is less than 1/2 the price.

Yup! They don't even have to gonads to test the Fujicon XF line-up. Pathetic.

Re-posting / citing that pathetic waffle is incredibly lame RichA - even

How do you really think Fuji x-trans would stack up?
I actually quite like the system, but the concept of the x-trans sensor
itself is serious bull**** - an answer to a problem which really doesn't
exist.

I think this comes back to the archaic idea that in-camera
correction of aberrations is somehow "wrong" and that the lenses
should 100% stand on their own two feet. This is no different than
people who claim IS/VR is a bad idea.


A simple "No, I have no better data" would have sufficed.
