Effect of Aperture on Sharpness

[beagle100]

Was looking for a DOF app for iOS when I stumbled upon this bit of wisdom previously unknown to me: an increase in aperture value increases DOF but slightly DECREASES focal sharpness.

E.g.: going from wide open to f/16 will increase the width of your in-focus depth but decrease your max focus clarity.

Could this be so? Had never heard this.

never heard of that? .... shocking
who woulda thunk it

Not me, apparently!
