>>3376302This is bait right?
If not then just to make sure no misinformation reaches new people: this is wrong. The larger the F-number, the more is in focus. Period.
This only becomes “fuzzy” when dealing with pinhole apertures, like f/256 or something. Even that depends on format. With some ultra large format like 20x24, this wouldn’t necessarily even get everything in focus. With normal formats though, once you get to pinhole apertures, essentially eventhing is in focus except for whatever is potentially a millimeter in front of the camera. Lenses with pinhole apertures will still work advance normal lenses of their focal length. Pinholes don’t actually focus light, they just take points of light and make them appear the size of the pinhole on the film/sensor medium. So technically everything is neither in focus or out of focus, just projected as aperture-sized points of light. With small apertures this becomes fuzzy because of diffraction, but still the same.
Lens SHARPNESS is what this anon is talking about. But he’s not even right: on many lenses f/8 isn’t close to the sharpest aperture. Usually the sharpest aperture is 2-3 stops from wide open, but it’s complicated to explain why: technically the wider open the less diffraction, but also the more stopped down the less abberations there are. The trade off reaches its maximum combined quality of low diffraction and lack of abberations differently on different lenses and depends on not only individual lens types, but also individual lens copies of the same type. For example I have a Nikkor SW 120mm f/8 for 4x5 and 8x10 large format photography. It is meant to be used around f/16 to f/22because Nikon has determined that those are the best working apertures for general use. For a fast 50mm f/1.2 lens, f/4 may be the sharpest aperture.
