Thanks petrochemist for the link ..good call
Huh? What's POI? Why do you need more MP as you reduce the focal length? Surely you chose the focal length for the field of view and then the pixels are the pixels! Unless you go heavily cropping then 16MP is plenty. But you can avoid cropping by using the right focal length. Or do you just want to take every shot with a fisheye and then crop as required? That's why zoom lenses were invented

Why are Nikon lenses "real" ?
E-M1ii, Pen-F and too many lenses
