The Sony α99 II is the flagship Sony A-mount camera featuring a full-frame 42.4-megapixel back-illuminated CMOS sensor that delivers high-resolution image while providing high sensitivity, minimised noise, and wide dynamic range. Its wide standard ISO range 100-25600 is expandable to even wider ISO 50-102400.

42.4-megapixel back-illuminated full-frame CMOS sensor
Boasting its approx. 42.4 effective megapixel resolution, α99 II has a 35mm full-frame CMOS image sensor with back-illuminated structure, widely expanded sensitivity range, and extra-low noise performance. It also has no optical low-pass filter that can compromise sharpness, so fine clarity and detail extend from edge to edge of every frame.

High-speed BIONZ X™ image processing engine and front-end LSI
With detail reproduction technology to capture the essence of realism, diffraction-reducing technology to maintain clarity even at smaller apertures, and area-specific noise reduction to lower noise adaptively and reproduce greater detail, the BIONZ X image processing engine finely tunes the image sensor's effective 42.4-megapixel (approx.) data for truer, clearer depiction. α99 II is supported by a new front-end LSI to boost image data handling.

Brilliant AF and AE tracking even at 12fps
Track your subject regardless of how it moves. Revolutionary Hybrid Phase Detection AF System can capture even quick imminent movements — thanks to dense AF point coverage over a wide area and accelerated readout by the new image sensor for high-efficiency processing of vast amounts of phase-detection information. Through this sophisticated AF system — and faster shutter action due to a newly developed charge unit in the shutter mechanism — you can shoot up to 12fps14 continuously with steadfast AF and AE tracking13, allowing you to catch decisive moments in sharp detail at the proper focus and exposure.

Tough magnesium alloy body, dust & moisture resistant
Designed for solid reliability and steady handling, the camera body is built to withstand the rigors of shooting in the field. Its internal structure and top, front, and rear covers are all made of strong, rigid magnesium alloy.
Enjoy carefree shooting in tough environments, with comprehensive dust and moisture resistance23 measures that help prevent water and dust from entering the body. These measures include sealing around the buttons and dials, as well as media jack cover and enclosure edges featuring tongue-and-groove joints for double protection to tightly interlock panels and components.

8fps live-view continuous shooting
The camera achieves continuous shooting of up to 8fps15 for live-view shooting, using an improved display algorithm for OLED Tru-Finder and LCD monitor. Minimised display time lag lets you easily keep tracking a subject in motion.

Flicker-free shooting
Flicker from fluorescent and other artificial lighting is automatically detected16 and the shutter is timed to minimise its effect on still images. This suppresses exposure and colour anomalies that can occur at the top and bottom of images shot at high shutter speeds, as well as exposure and colour inconsistency between continuous shots. You can take images under indoor lighting with confidence.

Hybrid Phase Detection AF System
α99 II has an AF sensor with 79-point phase-detection and an image sensor with the world’s largest array of 399 focal-plane phase-detection AF points. Sony’s original Translucent Mirror Technology allows light to reach the dedicated AF sensor and the image sensor simultaneously, so both phase-detection AF systems are always active. The AF algorithm has also been revised to support the Hybrid Phase Detection AF System. Its broad coverage and high density enable higher AF speed and precision as well as notably improved tracking performance.

79 Hybrid Cross points
Discover breakthrough autofocusing and tracking reliability. Sony’s Hybrid Phase Detection AF System provides a dedicated AF sensor with phase-detection AF points (79 including 15 cross points) for horizontal detection. This AF point area is entirely covered by the 399-point focal-plane phase-detection AF sensor for vertical detection, so all 79 AF points can function as selectable Hybrid Cross points. By spreading points densely over an area and fine-tuning the balance between responsiveness and stability, Sony optimises subject tracking to stay locked on almost any type of subject without being affected by subject patterns. 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.

Precision AF effective down to EV-4 brightness
Low-light AF detection down to EV-4 (central focus point) has been achieved. The precision AF system will function properly even when shooting dimly lit scenes at high ISO. This opens dramatic new possibilities in low-light and night shooting.

Body-integrated 5-axis image stabilisation
This all-direction stabilisation system is fine-tuned for high-resolution image sensors to compensate accurately for five types of camera shake that can compromise handheld shooting of α99 II 42.4MP21 images. Designed for A-mount models, the body-integrated system offers extremely high performance in both stills and movies, whether you're shooting at longer focal lengths, in close-ups, or at night. Real-time effects can be monitored via live view. Camera shake compensation is equivalent to using a 4.5-step22 faster shutter speed, allowing you to take advantage of a wider range of shutter speeds.

4K movie recording
Thanks to full pixel readout without pixel binning, 4K movie recording in the Super 35mm format exhibits more detail-rich superior clarity than typical 4K movies since Super 35mm collects approximately 1.8 times as much information as needed for 4K movie output. Also, the XAVC S format27 allows 4K recording at maximum bitrate of 100Mbps to capture fine details of movement in movies.

14-bit RAW format
For RAW recording, 14-bit RAW output and 16-bit image processing help preserve maximum detail and produce images of the highest quality with rich tonal gradations. The 14-bit RAW (Sony ARW) format ensures optimal quality for later image adjustment (via Image Data Converter or other software). 1: Image Sensor 2: Newly developed high-speed front-end LSI 3: 16-bit image processing.

Location data acquisition via Bluetooth
Use Location Information Link to make the most of your camera anywhere you go together. After the camera has been paired to the PlayMemories Mobile app26 installed on a compatible mobile phone or tablet device, it can acquire location data from the mobile device and record that data with still images. The acquired location data can also be used to correct the camera’s date/time and location settings. The PlayMemories Home application can then be utilised on a personal computer to organise still images imported into the computer on a map.
