"Almost any lens is sharper stopped-down than it is wide-open. So
besides focusing better and more accurately, a fast lens is usually
sharper at the same aperture as a slower lens, simply because it's been
stopped-down more."
That's from an article on photosig.
I don't think that's true. It's easier to make a sharp slow lens. A
50mm f3.5 @ f8 I wouldn't be surprised if it was as sharp or SHARPER
then a 50mm f1.4 @ f8.
Am I wrong, or is the article's statement wrong??
