f/8
Common lens opening
F/8 is a camera aperture setting indicating the ratio between lens focal length and the diameter of the opening admitting light.
At f/8, the aperture is one-eighth the focal length—a middle setting offering good sharpness and depth of field.
Photographers often consider f/8 a sweet spot where most lenses perform at their best: When in doubt, shoot at f/8.
