SONY ALPHA A99 MK II CAMERA
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-point AF sensor provides high-precision focusing and depth detection, while the 399-point focal-plane AF sensor on the image sensor supplies wider coverage. During continuous shooting at up to 12fps, AF tracking captures motion once nearly invisible to human eyes.
79 Hybrid Cross AF points for quick precise focus
79-point Hybrid Cross AF effectively captures your subject. While 79 AF points of the dedicated phase-detection AF sensor are for horizontal detection, 399 AF points 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. Cross measurement reduces influence from the subject pattern, so you have fast, precise focusing for just about any type of subject. Moreover, the very central AF point also functions as an F2.8-sensitive sensor that supports lenses as bright as a minimum F-value of 2.8 or lower.
Fast continuous shooting with AF/AE tracking
The camera provides improved processing speed and a shutter mechanism to attain an unprecedented continuous shooting speed of up to 12fps (up to 8fps in live-view shooting) with AF/AE tracking.
Boosted CMOS sensor resolution and sensitivity
Advantages of back-illuminated image sensor design
Light-collection efficiency is enhanced by a back-illuminated image sensor with AR coating and gapless on-chip lens design that realizes uniform light penetration regardless of lens center or peripheral areas.
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, α99 II high resolution is optimized with body-integrated 5-axis SteadyShot 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.
4K high-resolution movies for A-mount users
Show your imagination in α99 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.
Accent movies with new quick and slow motion
Use “S&Q” mode to pick 1fps to 120fps (100fps) in eight steps, up to 60x (50x) quick motion and 5x (4x) slow motion, and record at full HD (50Mbps). Quick motion is like a time-lapse movie or deframing.
