I have read that, from an optics perspective only, F-8 is in general the best optical setting for most lenses (though obviously not every image will be best at F-8). If this is true, does this suggest that parameters such as diffraction and aberrations are minimized at F-8? Some other reason? Or is this simply not true and F-8 is not generally the best optical condition?
Thanks in advance for your help, it is much appreciated.
That is a generalization and does not apply to many lenses. Most of my prime lenses are best at around f/5.6 and the Nikon 35mm AF-S DX f/1.8 I have is actually best at f/4. You can find resolution charts for most lenses on the internet.
