Sony Alpha a9 Top Features
The Alpha a9 electronic viewfinder offers a liberating experience for all types of image making with blackout-free shooting. You have a continuous, uninterrupted view of the subject with a 60 fps live-view refresh.
Silent, vibration-free electronic shutter
The evolved electronic shutter in the Alpha a9 operates silently, without mechanical noise that can be disruptive in a quiet environment. The electronic shutter is vibration-free which also minimizes blur, further contributing to superior resolution and image quality. What's more, its maximum 1/32000 sec speed exceeds the limits of mechanical systems.
Dual Media Slots
Two media slots are provided for still and movie storage: one for SD cards and one for SD cards and Memory Stick. The lower card slot is UHS-II compatible for fast write speed. Still or movie data can be simultaneously recorded to both cards for backup, or RAW images can be recorded to one card while JPEG images are recorded to the other.
Continuous AF/AE Calculation
It employs an ingenious blend of mirrorless construction and new speed enhancing technologies to allow autofocus and auto-exposure calculations to continue even between the frames. Up to 60 calculations are made per second.
5.0-step 5-axis image stabilization
A newly developed 5-axis optical image stabilization unit and high-precision gyro sensors provide a 5.0-step* shutter speed advantage for full-frame images. Camera shake is effectively compensated for in 5 axes. Stabilization is applied to the live-view image, making it easier to frame fast-moving subjects. Effective stabilization is provided for movies as well as stills.
Fast, dependable focus
Fast phase-detection autofocus that offers excellent tracking. The whole system has been optimized for speed, achieving approximately 25% faster AF operation than the a7R II. An uninterrupted stream of up to 60 AF calculations per second maximizes AF performance. AF calculationcontinues even during electronic shutter release so that complexsubject motion can be tracked and sudden movements can be predicted.693 phase-detection autofocus points in a high-density focal planephase-detection AF system cover approximately 93% of the image area.
FTP File Transfer
In addition to wireless LAN capability, a new terminal for wired LAN connection allows convenient transfer of high-volume still image files to a specified FTP server where they can be viewed and managed via a local computer. A wired LAN connection provides high stability and transfer speeds for large image files, and is an ideal solution for situations where large amounts of data must be transferred quickly and reliably.
A high-luminance 3686K-dot Quad-VGA OLED Tru-Finder reproduces the finest details, and a 0.78x magnification with outstanding corner-to-corner clarity. The ZEISS T coating greatly reduces reflections. A 120 fps frame rate provides a smooth viewfinder image with minimum display motion blur, and high luminance keeps the brightness of the viewfinder image close to that of the actual scene. There's even a fluorine coating on the outermost viewfinder lens that repels fingerprints, dust, water, oil, and dirt.
Double Battery Life
A newly developed NP-FZ100 battery offers approximately 2.2 times the life of the previous NP-FW50. Up to approximately 480 still frames can be captured on a single charge. Up to approximately 480 still frames* can be captured on a single charge. But that's just with the body alone. The optional VG-C3EM vertical grip houses two batteries that let you shoot up to 950 images* in continuous mode. And when you need serious stamina for long sessions there's the NPA-MQZ1K Multi Battery Adaptor Kit that can hold up to four batteries.
And Many More Features
Drive and Focus Mode Dials
Stacked independently operable dials allow fast selection of drive and focus modes. Quickly select the single or continuous drive mode, or the single AF or continuous AF focus mode, for example, without having to scroll through menus. Both dials are lockable.
The multi-selector provides a fast, efficient way to shift focus points: simply press the up, down, left, or right button. When reviewing shots in playback mode the multi-selector is used to select the previous or next image.
