Quick AF Full HD Movie
Even when shooting movies at Full HD
resolution*, the 57 employs speedy
full-time continuous phase-detection
autofocusing. Most interchangeable
lens cameras revert to contrast-
detection AF that slowly hunts for the
correct focus when shooting movies.
But the 57 delivers the same swift,
accurate focusing as during still
photography to capture even fast-
moving subjects with clarity. You can
even lock exposure, switch the focus
point, enjoy digital zooming and more
while shooting movies for expanded
creative control.
