Use for relatively static compositions with subjects that will stay in selected focus area. Focus areas outside high-speed crop can not be selected when high-speed crop is on ( 41). User selects focus area manually, but camera uses information from multiple focus areas to determine focus. If subject leaves selected focus area even briefly, camera will focus based on information from other focus areas (focus area selected in viewfinder does not change). Use when following erratically moving subjects in continuous-servo AF and in other situations in which it is difficult to keep subject in selected focus area. • When high-speed crop is on ( 41), focus areas outside high-speed crop can not be selected, and camera will not use these areas to determine focus.
