#Manual Focus

mænjuəl fokəs

Manual focus is when a photographer manually focuses their lens so as to select what is in focus in the frame. Some lenses do not have autofocus and are manual focus only, but pretty much any lens can be used to focus manually. Switching to manual focus can be useful in scenarios that are overwhelming to an autofocus system such as very low light, low contrast, or backlighting. It’s also useful when shooting macro where minute focusing can often be better determined by a human than an autofocus system or when pre-focusing for a shot.
