I guess it’s something with the quality of the glass. Modern lenses are dead sharp and have very little flaring, ghosting, chromatic aberrations and low distortion. They also focus instantly with zero noise.

Say there’s a short Nikon 35mm f2 which has very bad ghosting situation, and it’s resolution is miles behind modern 35mm f1.8 mirrorless.

If you don’t like certain photos you can just hide or remove them from the gallery.

5x7 is a different crop from 4x6 so it’s hardly possible to have both.

My advice don’t print 4x6 its just too small for a good picture.
