* DLA (Diffraction Limited Aperture) is the result of a mathematical formula that approximates the
aperture where diffraction begins to visibly affect image sharpness at the pixel level.
Diffraction at the DLA is only barely visible when viewed at full-size (100%, 1 pixel = 1 pixel) on a display or output to a very large print.
As sensor pixel density increases, the narrowest aperture we can use to get perfectly pixel sharp images gets wider.
DLA does not mean that narrower apertures cannot be used.
And in fact, higher resolution sensors generally continue to deliver more detail well beyond the DLA -
until the "Diffraction Cutoff Frequency" is reached (a much narrower aperture).
The progression from sharp the soft is not an abrupt one - and the change from immediately prior models is usually not dramatic.
Check out this specific
diffraction comparison example
using the ISO 12233 chart comparison tool.
The mouseover feature will show you the degradation at f/11 compared to f/5.6.
