180K-pixel RGB sensor workflow, allowing you to temporarily switch modes during a shoot — for instance, if you
shoot mainly using auto-area AF but want to use single-point AF to achieve pinpoint focus
on a bride’s eye when needed. Furthermore, AF compatibility down to -4 EV* at the central
focus point and -3 EV* at all other points enables you to focus smoothly on low-contrast
subjects such as a bride in a white dress.
