When photographers talk about lens diffraction, they are referring to the fact that a photograph grows progressively less sharp at small aperture values – f/16, f/22, and so on.
Diffraction is an optical effect which limits the total resolution of your photography — no matter how many megapixels your camera may have. It happens because light begins to disperse or "diffract" when passing through a small opening (such as your camera's aperture).
29 de sept. de 2021 · But there’s a downside to smaller apertures when it comes to achieving an optimally sharp image: as apertures get smaller, images get less sharp and can even end up with undesirable blurring effects. This is known as lens diffraction.
DIGITAL CAMERA DIFFRACTION, PART 2. The exact value of the diffraction-limited aperture is often a contentious topic amongst photographers. Some might claim it's at f/11 for a given digital camera, while others will insist that it's closer to f/16, for example.
Understanding how diffraction affects your camera can help you pick out the best lens to use for a certain shoot, on a certain camera for optimal image quality. For example, if you need more depth of field for a landscape image, an ultra-wide-angle lens will help, because it will have a much greater area in focus, even at larger apertures.
17 de may. de 2024 · Diffraction versus F-stop. As shown above, when the lens (any focal length) gets stopped down to f/8 or narrower, the Airy disc diameter grows larger than two pixels (8.7 microns for Nikon Z9). As soon as this 2-pixel threshold is reached, some image softening starts. At f/8, diffraction is barely noticeable. Diffraction starts growing in leaps ...
