Why to buy Sony Alpha a9 II Mirrorless Digital Camera :
Sony Alpha 9 II Full-frame Mirrorless Interchangeable-Lens Camera
Created specifically to support working professionals in the fields of sports photography and photojournalism, the Alpha 9 II delivers unmatched performance including blackout-free continuous shooting at up to 20 frames per second with Auto Focus and Auto Exposure tracking at 60 calculations per second3, plus continuous shooting at up to 10 fps with mechanical shutter. Evolved Artificial Intelligence autofocus with Real Time AF tracking6 for accurate image acquisition and built-in connectivity and file delivery for the professional’s workflow with file transfer over SSL or TLS encryption (FTPS) for increased data security
24.2 MP1 stacked Exmor RS CMOS sensor
From the world’s largest sensor manufacturer comes the fastest 35mm full-frame 24.2 MP1 stacked Exmor RS CMOS sensor, w/ incredible high-speed performance and outstanding image quality. Separate circuit and pixel layers allow for a significant increase in processing speed for the large volume of data that can also be temporarily stored in internal memory, contributing to a substantial increase in overall pixel readout speed. The combination of this advanced sensor and evolved BIONZ X processing enables blackout-free8 continuous shooting at up to 20 fps2with up to 60 AF/AE tracking calculations per second3, silent vibration-free electronic shutter speeds up to 1/32000 sec, Anti-Distortion Shutter operation14, and other capabilities that add up to unprecedented speed from a full-frame camera without interference from mechanical devices.
Up to 20fps2 with up to 60 AF/AE tracking calculations per sec.3
Capture all the action at the highest speed. A combination of groundbreaking high-speed full-frame stacked Exmor RS CMOS sensor with integral memory and BIONZ X processor with DRAM enables incredible completely silent continuous shooting up to 20fps2 at full 24.2MP1 resolution in RAW+JPEG with continuous AF/AE (autofocus and auto exposure) tracking at 60 calculations per second3 and no EVF or LCD blackout8. The large high speed buffer allow for up to 361 JPEG images or 239 compressed RAW images16 in a single burst. It is also possible to shoot up to 10 fps2 using the mechanical shutter.
AF/AE calculations up to 60 times/sec. 3
The extremely high readout speed of the Alpha 9 II Exmor RS sensor allows for autofocus and auto exposure (AF/AE) to be calculated up to 60 times per second3 and is virtually uninterrupted, both while composing the image and even upon releasing the shutter. You can depend on the continuous autofocus to lock onto and track erratically moving subjects with significantly high speed, precision, and reliability, while exposure automatically adjusts even through sudden brightness changes for consistently accurate exposure.
Designed to improve the speed of news agencies workflow, the Alpha 9 II features a Voice Memo function that allows spoken information to be attached to images which can convey important information when sent to the editor. Voice memos4 up to 60 seconds in length can be recorded and attached as a WAVE (.wav) file with the same name as the image file which can be transferred via FTP along with the corresponding image data without the need for additional equipment or software. Voice memos cannot be attached to movie files. Additionally, a photographer can also use the ‘Transfer & Tagging add-on’ Imaging Edge application to transfer voice tags with the images to their mobile device and have the voice memos automatically converted to text and added to the JPEG images in the form of IPTC metadata.
Real-time Tracking6 automatically tracks the subject
Real-time Tracking6 is a state-of-the-art feature that employs artificial intelligence to tenaciously track moving subjects when shooting stills or movies. Accurate focus is maintained automatically while the shutter button is half-pressed. An advanced subject recognition algorithm uses color, pattern (brightness), and subject distance (depth) data to process spatial information in real time. If the subject is a person, AI is used to detect and keep track of the subject’s eye and face in real time for extremely high tracking precision. The focus area will seamlessly change between face and eye according to the condition of the subject. The subject to be tracked can also be specified by touching it on the monitor when the Touch Tracking function is engaged. Tracking On can also be assigned to a custom key so that the user can initiate tracking at any time.
Real-time Eye AF (Human)
Real-time Eye AF employs artificial intelligence to detect and process eye data in real time, and track the subject’s eye with unprecedented precision. This function can be activated via an assigned custom key, or by simply pressing the AF-ON button or half-pressing the shutter button. When used with the Real-time Tracking function, tracking will continue even if the camera is temporarily unable to locate the subject’s eye, so it is easier than ever to shoot dynamic portraits and moving subjects. In addition to automatic eye selection when using Eye AF, it is also possible to manually preselect the subject’s right or left eye5.
5 GHz7 wireless LAN support
The camera’s built-in wireless LAN functionality has been updated, adding a 5 GHz band7 to the 2.4 GHz band (IEEE 802.11a/b/g/n/ac standards are supported). The benefits of 5 GHz communication include less interference as well as faster, more stable data transfer.
FTP transfer functions
FTP background transfer capability is provided so the user can continue to shoot still images while image files are being transferred to an FTP server via a wired or wireless connection. It is also possible to specify protected and other file types for transfer, transfer single files by pressing an assigned custom key, specify JPEG or RAW file formats, and more. Up to nine FTP servers can be memorized for quick recall. In addition to direct transfer to an FTP server via a wired or wireless connection, transfer via the Transfer & Tagging add-on application installed on a mobile device is also possible. All this versatility can contribute greatly to the speed and efficiency of professional workflows. Movie files cannot be transferred and FTP transfer is not available during movie recording
