The a99 II delivers the next level in significantly swift high-precision AF, faster continuous shooting, and stunning resolution — the best performance in A-mount.
Revolutionary features in trusted style: New AF-tracking rapid continuous shooting. Reveal worlds unknown.
Experience ingenuity perfected through Sony’s latest camera innovations: newly developed high-speed high-precision Hybrid Phase Detection AF, AF/AE tracking in 12fps continuous shooting, body-integrated 5-axis image stabilization, and advanced 4K movie functions.
Advantages of Hybrid Phase Detection AF System: Sony’s translucent mirror realizes proprietary AF system Translucent Mirror Technology enables the Hybrid Phase Detection AF System consisting of two AF sensors. The dedicated 79-point4 AF sensor provides high-precision focusing and depth detection, while the 399-point5 focal-plane AF sensor on the image sensor supplies wider coverage. During continuous shooting at up to 12fps3, AF tracking captures motion once nearly invisible to human eyes.
79 Hybrid Cross AF points for quick precise focus: 79-point Hybrid Cross AF6 effectively captures your subject. While 79 AF points4 of the dedicated phase-detection AF sensor are for horizontal detection, 399 AF points5 of focal-plane phase-detection AF sensor handle vertical detection. Moreover, the focal-plane phase-detection AF sensor coverage area includes the dedicated phase-detection AF sensor area so 79 superimposed points function as selectable Hybrid Cross AF points.
Enhanced subject-tracking performance: Consistent high-precision tracking is achieved by taking advantage of vast AF data.
AF supports scenes as dark as EV-4: Light-sensitive AF lets you shoot to EV-4 (central focus point).
Eye AF for more precise focusing: Keep the subject’s eye in focus, even if the face is turned at an angle.
Stunning high resolution: a99 II features a 35 mm full-frame 42.4-megapixel 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 50-10240010.
Optical 5-axis image stabilization: As effective as using 4.5-step faster shutter speed 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 SteadyShot INSIDE image stabilization, fine-tuned to match its 42.4-megapixel9 performance. You can zoom in on faraway subjects, shoot close-ups, and take night scenes with nearly shake-free clarity in stills and movies.
4K high-resolution movies for A-mount users: 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 35 mm size frame due to full pixel readout without pixel binning.
Stunning high resolution with Super 35 mm: Use “S&Q” mode to pick 1fps to 120fps (100fps) in eight steps, up to 60x (50x) quick motion and 5x (4x) slow motion16, and record at full HD (50Mbps). Quick motion is like a time-lapse movie or deframing.
Ample features for greater ease and reliability: You’ll appreciate new a99 II ergonomics. The redesigned body is 8% smaller than the a99, thanks to the re-examination of the internal layout and the reduced size of the 5-axis image stabilization 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
