A99 II features a 35mm full-frame 42.4-megapixel 8 back-illuminated CMOS sensor that delivers high-resolution image while providing high sensitivity, minimized noise, and wide dynamic range. Its wide standard ISO range 100-25600 is expandable to even wider ISO 50-1024009. Shooting should be as steady as possible to minimize the negative effect of camera shake blur. So, A99 II high resolution is optimized with body-integrated 5-axis Steady Shot INSIDE image stabilization, fine-tuned to match its 42.4-megapixel performance. You can zoom in on faraway subjects, shoot close-ups, and take night scenes with nearly shake-free clarity in stills and movies. Show your imagination in A99 II 4K movie recording, as the back-illuminated full-frame image sensor transforms your vision into reality. You’ll achieve expanded expressive power in 4K resolution when shooting in the full-frame 4K format of the sensor. And, you can capture stunning high resolution when shooting in Super 35mm size frame, due to full pixel readout without pixel binning. You’ll appreciate new A99 II ergonomics. The redesigned body is 8% smaller than the A99, thanks to re-examination of internal layout and reduced size of the 5-axis image stabilisation system. Meticulous attention has been paid to the smallest details, so the new camera provides excellent operability and reliable body rigidity in addition to downsized body dimensions.
