There is no theoretical limit to the aperture of a lens or the fastest possible lens stop. Lenses with larger apertures are called fast because this allows the photographer to use a higher (faster) shutter speed! What is the theoretical fastest lens possible? Why are lenses called “fast”?Ī lens with a larger aperture lets more light into the camera. To make this less confusing, check out our video which explains the differences between aperture and fstops. F stops are calculated by dividing a lenses focal length by its aperture. But aperture is commonly incorrectly referred to when talking about a lenses f-stop, which is a measurement of how much light a lens funnels into the camera. Aperture is technically the diameter of your lens opening that allows light into the camera. For an in depth explanation, watch our video explanation of aperture and depth of field! Is aperture the same as f-stop? The larger the hole, the greater the angle of light entering the camera, which results in a shallower depth of field. Simply put, the aperture of a lens is the size of the hole allowing light to pass through to the camera.
