Precision AF effective down to EV-330 brightness - Low-light AF detection down to EV-330 at ISO 100 has been achieved. The precision AF system will function properly even when shooting dimly lit scenes. This opens dramatic new possibilities in low-light and night shooting.
Enhanced Eye AF - Eye AF can capture intriguing facial expressions with enhanced accuracy through 30% improved precision of eye detection. This enhanced feature automatically focuses on and even tracks focus on a subject’s eye as the face moves or turns to a 3/4 view, extending your freedom to frame a great shot.
693-point focal-plane phase-detection AF - a9 brings you 693 phase-detection AF points in a high-density focal-plane AF system, providing distinctively wide and dense AF point coverage over approximately 93% of the image area. This enables more accurate, efficient, and reliable focus on subjects throughout the frame.
Recall Custom Setting during Hold - Memorized exposure settings (shutter speed, aperture, AF area, etc.) can be assigned to custom buttons for temporary recall while the button is held. For example, if you shoot sports in a stadium, you might want to quickly capture a shot of the scoreboard, requiring a temporary change in exposure, and then go back to the action.
Focus Area Registration function - Frequently used focus area setting can be memorized and recalled via custom button assignments for fast, convenient one-push access when needed. This can be handy when the ideal focus point changes often, for example, with a tennis stroke. In addition to the focus point, the focus area can be set as required for optimum focus performance with the scene being photographed.
AF/AE-tracking continuous shooting with A-mount lenses - The body’s 693-point focal-plane phase-detection AF provides wide-area coverage, fast response, and high tracking performance, not only for E-mount but also for A-mount lenses31 with use of a mount adaptor (LA-EA3). Continuous shooting of up to 10fps with AF tracking is possible.
Body-integrated 5-axis image stabilization - The body-integrated image stabilization system is fine-tuned to compensate accurately for 5-axis camera shake that can compromise handheld shooting. This gives you extremely high performance in both stills and movies, whether you're shooting at longer focal lengths, in close-ups, or at night. Camera shake compensation is equivalent to using a 5.0-stop faster shutter speed, allowing stable determination of composition at times of capturing subjects in high-speed motion. Real-time effects can be monitored via live view. (1) Yaw (2) Pitch (3) Roll

High-resolution 4K movie recording - Capture outstanding high-quality 4K movies with this latest full-frame camera. Full-pixel readout without pixel binning for high-resolution 4K movies makes it possible to deliver detail-rich full-frame movies via the oversampling effect achieved by condensing approximately 2.4 times the amount of data required for 4K (6K equivalent) for 4K output (QFHD: 3840 x 2160). Furthermore, the high speed of the newly developed image sensor reduces the rolling shutter effect.
Improved Fast Hybrid AF for movie shooting - Keep images sharp and clear in shooting 4K movies. Fast Hybrid AF for movie recording has evolved and its AF area has been extended to nearly the same width as that for stills, enabling high-speed high-precision AF throughout the frame. Also, further reduction of speed at the “low” end of AF speed enables more pronounced slow focus effects.
XAVC S for high-bitrate recording - XAVC S format is used for 4K and HD recording. High bitrates of up to 100Mbps for 4K 30p (25p)/24p recording, and up to 50Mbps for full-HD 60p (50p)/30p (25p)/24p recording, ensure beautifully detailed movies with minimal compression noise. Since 100Mbps recording is possible even at the highest 120fps in full-HD, high-quality slow-motion sequences can be created during post processing.
Zebra functions - Simplify exposure with Zebra. Target video brightness from 0-109%, set +10% and -10% range, check zebra pattern for areas in range, and see minimum brightness to avoid blown-out highlights.
Slow and Quick motion - Vary the pace of movie footage to enhance viewing interest and enjoyment. Instantly selectable via a dial, “S&Q” mode supports slow and quick motion, with frame rates from 1fps to 120fps (100fps) selectable in eight steps for up to 60x (50x) quick motion and 5x (4x) slow motion, recordable at Full HD (50Mbps) quality. You can “play with time” by compressing movement or extending a moment, and then accent ordinary footage with these interludes to add comic or dramatic emphasis.
