Originally posted by lytrytyr There's a good example of this effect documented by Photozone,
where the Nikon 28/1.8 G earns 2.5 stars on 1", 3-3.5 on APS-C, and 4 on FF.
The corner resolution is at best "good" on 1",
but never less than "very good" on FF.
For various reasons,
including the higher pixel density needed on small formats,
the intuitive concept of "cropping away bad corners"
doesn't necessarily work out in practice.
This article also makes a good point:
Full Frame vs while it's cheaper for a manufacturer to only cover the FF sensor exactly with no wiggle room (which is the case with cheap lenses), some (better, more expensive (to buy and to manufacture)) lenses cover a larger circle, so there are no "bad corners" on FF.
Maybe someone smarter can explain to me how the aps-c sensor could tell the difference between a lens that couldn't resolve the individual slats in the blinds in the example image, and a lens that can resolve a lot more? Lets say white bb pellets
in between the slats just so no one can say "but it resolves the slats... kind of, barely..." I'm not being snarky here, I genuinely want to understand what to me seems impossible to understand even after I accepted that the way I thought it is isn't the way it is. How can the smaller sensor tell the difference when it can't resolve the detail? Smaller pixels also mean less photos detected by each pixel or more noise because each pixel gets more photons than it can handle, doesn't it? Isn't that one of the disadvantages of smaller sensors?

can any dslr/FF/4/3 or even middle format resolve the individual pores on human skin from a portrait distance? If it can't, how can it measure the resolving limit/sharpness of a lens better than a larger format (sensor or film)? I'm slipping back to my original understanding because it's the only one that seems to make any sense, but I'll happily accept the reverse if someone can explain it to me. I can't understand something no one explains.
