        In optics, the f-number (sometimes called focal ratio, f-ratio, f-stop, or relative aperture[1]) of an optical system is the ratio of the lens's focal length to the diameter of the entrance pupil.[2] It is a dimensionless number that is a quantitative mea

    Diffraction is a loss of sharpness or resolution caused by photographing with small f/stops. The same softening effect happens when photographing through diffusion cloth or window screens. Anytime you look or photograph through small holes ......

    The resolution of an optical imaging system – a microscope, telescope, or camera – can be limited by factors such as imperfections in the lenses or misalignment. However, there is a fundamental maximum to the resolution of any optical system which is due ...

    Diffraction-Limited Imaging If an image is made through a small aperture, there is a point at which the resolution of the image is limited by the aperture diffraction. As a matter of general practice in photographic optics, the use of a smaller aperture (...

    © 2010 KenRockwell.com You'll notice for f/8 read on the scale, I set f/13 on the aperture ring. Easy! Hint: On my cameras, I stick a tiny table that simply says f/2.8 -> f8, f/5.6 -> f/11, f/11 -> f/16 and f/22 -> f/22. That covers it! For the LEITZ SUPE...
