Sony announces Alpha A9 Full Frame mirrorless camera with stacked sensor
Sony has announced the A9 full frame mirrorless camera with 24.2 megapixels. It is the world’s first Full-frame stacked CMOS sensor camera. According to Sony the A9 is the most technologically advanced, innovative digital camera that Sony has ever created.
Sony A9 Full Frame Mirrorless Camera with stacked sensor
Still Burst rate:
It can shoot still images at a huge 20frames per second for 241 RAW images or 362 jpeg images.
Silent and vibration free shooting at upto 1/32000 seconds. 1/32000 shutter speed is available only in the S and M modes. The highest shutter speed in all other modes is 1/16000.
There are 693 focal plane phase detection AF points and 60 AF/AE tracking calculations done per second. This covers approximately 93% of the frame and such fast calculations of the focusing system ensures that even the fastest moving subjects are reliably captured and tracked across the frame.
The camera also gives 5 axis in-body image stabilization with 5 stops shutter speed advantage.
All this is made possible due to the 35mm full-frame stacked Exmor RS™ CMOS sensor – the world’s first of its kind – which enables data speed processing at up to 20x faster than previous Sony full-frame mirrorless cameras. This unique sensor is paired with a brand new, upgraded BIONZ X processing engine and front-end LSI that maximises overall performance.
Further, when the shutter is released while shooting stills, the electronic viewfinder functions with absolutely no blackout, giving the user a seamless live view of their subject at all times. This feature truly combines all of the benefits of an electronic viewfinder with the immediacy and “in the moment” advantages that not even the finest optical viewfinders can match, and is available in all still image modes including high speed 20 fps continuous shooting.
The Fast Hybrid AF system:
Pairing the speed and excellent tracking performance of phase detection AF with the precision of contrast AF – achieves approximately 25% faster performance when compared with α7R II, ensuring all fast-moving subjects are captured.
Viewfinder:
The α9 features an all-new, high-resolution, high-luminance Quad-VGA OLED Tru-Finder with approximately 3,686k dots for extremely accurate, true-to-life detail reproduction. The new Tru-Finder, which is the highest resolution viewfinder Sony has ever incorporated in an α camera, features an optical design that includes a double-sided aspherical element, helping it to achieve 0.78x magnification and a level of corner to corner sharpness that is simply outstanding. The EVF also utilises a ZEISS® T* Coating to greatly reduce reflections, and has a fluorine coating on the outer lens that repels dirt.
This all adds up to a luminance that is 2x higher than the XGA OLED Tru-Finder from the α7R II, creating a viewfinder image with a brightness level that is nearly identical to the actual scene being framed, ensuring the most natural shooting experience. The frame rate of the Tru-Finder is even customisable, with options to set it for 60 fps or 120 fps to best match the action.
High Sensitivity and Wide Dynamic Range
The 24.2 MP full-frame stacked CMOS sensor is back-illuminated, allowing it to capture maximum light and produce outstanding, true-to-life image quality. The sensor also enables the diverse ISO range of 100 – 51200, expandable to 50 – 204800, ensuring optimum image quality with minimum noise at all settings.
ISO Still images, mechanical shutter: ISO 100 – 51200 expandable to ISO 50 – 204800.
ISO Still images, electronic shutter: ISO 100 – 25600 expandable to ISO 50 – 25600.
ISO for Movie recording: ISO 100 – 51200 expandable to ISO 100 – 102400.
The enhanced BIONZ X processor plays a large part in image quality as well, as it helps to minimise noise in the higher sensitivity range while also reducing the need to limit ISO sensitivity in situations where the highest quality image is required.
The new α9 also supports uncompressed 14-bit RAW, ensuring users can get the most out of the wide dynamic range of the sensor.
4K Video Capture
The new α9 is a very capable video camera as it offers UHD 4K (3840x2160p) video recording across the full width of the full-frame image sensor. When shooting in this format, the camera uses full pixel readout without pixel binning to collect 6K of information, oversampling it to produce high quality 4K footage with exceptional detail and depth. Recording is also available in the popular Super 35mm size.
Additionally, the camera can record Full HD at 120 fps at up to 100 Mbps, which allows footage to be reviewed and eventually edited into 4x or 5x slow motion video files in Full HD resolution with AF tracking.
The files are recorded in XAVC S codec in 8 bits at 100Mbps. Unfortunately only 8 bits and only 100Mbps is not great for pro video.
The camera has Ethernet port for faster file transfers. It also has dual SD card slots so files can be simultaneously be recorded to both the cards. If you are a still photographer and want to shoot both RAW and jpeg, then you can record both to different cards.
The Sony A9 will start shipping in June 2017 at a price of $4499 US Dollars.
