Beautiful images with reduced noise
Building on the capabilities of the back-illuminated image sensor the BIONZ XR engine reveals even higher subjective resolution combined with exquisite detail and texture even in medium- and high-sensitivity ranges. Impressively low levels of noise are achieved throughout the standard range of ISO 100-51200 (expandable to ISO 50-204800 for stills and ISO 100-102400 for movies).
