Sony Alpha 99 II Corps

Camera Sony A99 II

The main features of SONY A99 II Camera are:

The flagship A-mount camera from SONY, the Alpha a99 II DSLR camera combines the power of a 42.4MP back-illuminated full-frame Exmor R CMOS sensor and a BIONZ X image processor with front LSI to create exceptional images at expanded Sensitivities up to ISO 102400 and 4K UHD video recording. The a99 II is designed for speed, with an ergonomic body design and a revamped shutter capable of 12 fps, with full AF and AE capabilities. It also uses a hybrid phase-detection AF system that combines a dedicated 79-point AF sensor with a 399-point on-chip focusing system for fast, accurate focusing in all conditions. And, for video, a new S&Q Motion setting enables Full HD video capture at a variety of frame rates from 1-120 fps.

Another big advantage of the a99 II is a 5-axis SteadyShot INSIDE stabilization system that can compensate for approximately 4.5 stops of shutter speed for sharper images. The camera also offers a 0.5" 2.36m-dot XGA OLED Tru-Finder rear LCD and a 3.0" 1,228.8k-dot rear LCD that can tilt up 134° and down 180°, as well as rotate 270° to work in a variety of positions In addition to all these features, the camera offers built-in Wi-Fi with NFC and Bluetooth that extends the camera's operability and can generate 14-bit raw files.

42.4 MP Exmor R BSI CMOS sensor and BIONZ X processor
Harnessing the power of a back-illuminated full-frame Exmor R CMOS sensor, the a99 II is capable of creating spectacular high-resolution images in a wide variety of shooting conditions. The back-illuminated structure is reinforced by the use of an anti-reflective coating and an on-chip chipless lens design that maximizes light-gathering capabilities, ensuring excellent low-light performance due to a sensitivity range of up to ISO 102400. Also, it forgoes the use of an optical low-pass filter to ensure the sharpest images.

This outstanding sensor is combined with the BIONZ X image processor and a newly developed front LSI that dramatically improves the speed and performance of the entire imaging system, enabling continuous shooting with AF/AE at up to 12 fps. In addition, it is possible to shoot at 8 fps with full live view support, meaning no blackout time while shooting. Another advantage of this configuration is the 16-bit image processing and 14-bit raw output that provides outstanding color fidelity and image quality.

SteadyShot INSIDE 5-axis image stabilization

Included in the a99 II is a SteadyShot INSIDE 5-axis image stabilization system. This compensates for the five types of camera shake that occur during manual shooting of still images and videos. This allows users to confidently use any lens, even adapted lenses, for critical images without blurring due to camera shake. This system will compensate approximately 4.5 shutter speed stops to work with a wide variety of subjects.

For long focal lengths, the system will correct for tilt and yaw settings. Macro and high-magnification images, on the other hand, will benefit from the inclusion of horizontal and vertical shift compensation. In addition, all shooting styles will gain the use of roll compensation. The 5-axis stabilization will work at all times, even when used with third-party lenses and adapters or lenses with built-in optical stabilization.

When using lenses that do not transmit image data to the camera, manual settings can be used to enter the correct focal length and ensure proper stabilization. In addition, the viewfinder can be used to preview the amount of compensation by pressing the shutter release button halfway or enlarging the image.

Hybrid phase detection AF system

Taking advantage of SONY's patented translucent mirror technology, the a99 II can use both a dedicated 79-point AF sensor and the 399-point focal plane AF system located on the image sensor at the same time. This provides lightning-fast autofocusing as well as wide coverage. The 79 cross-type hybrid AF points improved its focusing accuracy by utilizing both the standard AF sensor and its 15 cross-type points with the focal plane points. This uses the AF sensor for horizontal detection, while the focal plane points handle vertical detection. In addition, the center AF point is sensitive at f/2.8 and the system can operate in illumination as low as -4 EV. Users can even benefit from AF capabilities while shooting at up to 12 fps or when using live view at up to 8 fps.

4K UHD video recording in XAVC S format
The a99 II is the first A-mount digital SLR camera to offer internal 4K UHD video recording at 30 or 24 fps. This is possible using the full-frame sensor or Super 35 format, which uses oversampling with full pixel readout and no pixel binning. This limits the moiré and aliasing common with high-resolution sensors. Video recording also benefits from live tracking thanks to the hybrid phase detection AF system and translucent mirror technology. The XAVC S format further enhances image capture by providing high bit rates of 100 Mbps in 4K and 50 Mbps with Full HD recordings. An additional benefit of this camera is the ability to switch between NTSC and PAL operations for worldwide use. When recording internally, users will record video at 4: 2: 0 sampling at 8-bit, however, to further enhance image quality, the a99 II has a clean HDMI output for use with an external recorder. This allows users to capture uncompressed 4: 2: 2: 2 video and save it in an edit-ready format.

The a99 II features a 3.5mm microphone input jack for compatibility with external microphones. For users who need more, the a99 II also supports the XLR-K2M XLR adapter from SONY for recording professional balanced XLR audio signals with phantom power and adjustable mic/line inputs. For audio monitoring, the a99 II features a 3.5mm headphone jack as well as real-time audio levels for visual reference.

Custom Color Profiles and S-Log3 Gamma

Support is available for S-Gamut3.Cine / S-Log-3 and S-Gamut3 / S-Log3 profiles that enable up to 1300% wider dynamic range for smoother color and tonal gradations, along with increased sensitivity and clarity in shadows. and midtones. These profiles also lend themselves to greater compatibility within a professional workflow and are well matched with the Cineon Log gamma curve for versatile post grading and color control. The S-Log3 gamma setting also offers an impressive 14-stop wide dynamic range for greater control over highlights and shadows, while the S-Gamut3.Cine profile can be used to mimic the qualities of scanned negative film with a wide gamut comparable to The DCI-P3 color space. In addition to the S-Log3 range, popular S-Log2 settings are also available.

Slow and fast motion

Take more control over your video capture capabilities with a variety of new frame rates available in S&Q mode. This will allow shooters to capture Full HD video in one of the steps between 1-120 fps. These settings will allow you to slow down the speed of the action as well as speed up a slow moving scene. This setting is also switchable NTSC / PAL.

1,228.8k dot 3.0" tilting LCD monitor

With a high resolution of 1,228.8 dots, the LCD will provide shooters with an excellent display for composing images, adjusting settings, and reviewing video and photos. It also tilts up 134° and down 180° and rotates 180° clockwise and 90° counterclockwise to work with multiple shooting angles. Use in sunlight is enhanced with the implementation of WhiteMagic technology that doubles the brightness of the display through an RGBW pixel structure.

0.5" 2.36M-Dot XGA OLED Tru-Finder Electronic Viewfinder

With its 4-lens optical system using double-sided aspherical elements, the viewfinder faithfully displays what will appear in your footage, including the effects of your camera settings. You'll enjoy rich tonal gradations and enhanced contrast. High-end features such as 100% frame coverage and 0.78x magnification enable comfortable and stable composition at eye level.
