USA is not all Detroit or Watts or Inglewood or Chicago ' s notorious southside . Why do the ignorant think all of Mexico is a war zone ? 99 % of Mexicans live in peace , like 99 % of Americans .

For example when shooting a portrait and you focus on an eye , it will continuously try to focus on the eye . During this continuous focus , it ' s in focus , then out of focus , cycling back and forth . Since the shutter can be fired now even if the subject is out of focus , I can sometimes get soft images . TLDR for stationary subjects , BBF may hunt too frantically and you might fire the shutter while not in focus . how do you deal with it ? Or is this disadvantage part of BBF ?
