Drew is right to a certain point. I doubt in 8x10 or even 16x20's prints one can easily tell the difference between the Nikon f4.5 vs the Nikon SW F8 Nikkor.
But do know Drew's opinion of the Nikon f4,5 being sharper than the f8 is in the clear minority. Do a web search and go back to threads over the last dozen years. He's clearly wrong here.
I cherry picked from three brand new 90 f4.5 and kept the one that was acceptable. This cherry picked sample is a competent optic but it's not even in the same league in terms of resolution performance as the Nikon 90 f8.
PS: The f8 is not difficult to focus in daylight conditions. It's also half the size and weight of the f4.5.
