What I found is for wide position F2.8 is sharper than F2

That actually makes sense.  I ran the numbers in an online calculator:

and it says that a camera with a 1/2.3" sensor will only hit diffraction limit at f:4.

Hi Borisk1

I have another diffraction calculator from the same site which show

http://www.cambridgeincolour.com/tutorials/diffraction-photography-2.htm

This calculator show a 1/2.3 sensor with 12 MP will hit diffraction limit at F3

Do you understand which is correct? I am no expert in this

the calculator you show is more complex with term like disk size and circle of confusion

Mine is more simple and it show different numbers

so which is correct? Anyone understand.  Please explain
