Noob here, I just acquired a better lens for my 450D which comes with the distance scale window. How is it used? I googled up some threads where old timers from the manual focus era will state that it's pretty useless on modern AF systems while others will keep mentioning about hyperfocal distances etc.
Can someone explain the function of the distance scale in simple enough terms? Much thanks in advance.
