The 20mm is pretty much sharp across the board until you get to the smaller apertures where maybe diffraction kicks in. It is just a teeny tiny bit sharper at f/2.8 than wide open. It actually has less chromatic aberration wide open. So there is not much advantage if at all in stopping it down. See
