What is hyperfocal distance and what is its use?

Adorama Photography answers the question "What is hyperfocal distance and what is its use"?


ExpoImaging ExpoAperture2 Depth-of-Field Guide - 2-Disc Kit


Many lenses no longer have complete or accurate depth of field markings. This tool gives photographers a full scale that can effectively be read with a single glance.  When all the parameters are chosen, the guide returns a range of apertures and the corresponding areas that will be rendered in focus for each f-stop. This two disc kit  includes a standard guide for 15-135mm lenses and a second disc for telephoto focal lengths from 70-600mm.
