Fast, dependable focus in any situation Extended focus versatility and precision Wide 693 point full-area phase-detection AF 693 phase-detection autofocus points in a high-density focal plane phase-detection AF system cover approximately 93% of the image area. Increased phase-detection AF image coverage and density ensures improved precision and unfailing focus in scenes where focus would be difficult to achieve with smaller coverage. Fast Fast Hybrid AF System Fast phase-detection autofocus that offers excellent tracking works with high-precision contrast autofocus to achieve significantly improved Fast Hybrid AF System performance. The whole system has been optimized for speed, achieving approximately 25% faster AF operation than the 7R II. Even fast-moving subjects are reliably captured. Steadfast Up to 60 AF calculations per second An uninterrupted stream of up to 60 AF calculations per second maximizes AF performance, precisely and reliably locking onto and tracking moving subjects in a wide range of photographic situations. AF calculation continues even during electronic shutter release so that complex subject motion can be tracked and sudden movements can be predicted with greater precision than ever before. Phase-detection AF coverage (693 points) Contrast-detection AF coverage (25 points) Enhanced Eye AF Eye AF automatically detects and focuses on the subject's eye. It has been notably improved in the 9, providing approximately 30% greater eye focus accuracy* even when shooting a moving subject in continuous AF mode. Face detection has also been updated for higher reliability when the subject is looking away from the camera, when the face is in partial darkness, and other challenging situations. * Compared to the 7 II. Fast focus with A-mount lenses The focal plane phase-detection AF system does its job even when an A-mount lens*1 is mounted via the optional LA-EA3 mount adaptor. 693-point focal plane phase-detection AF provides wide-area coverage and fast response for A-mount lenses as well as E-mount types, offering high tracking performance for an extensive lineup of lenses. A software update*2 for the LA-EA3 will allow continuous shooting with AF and AE tracking at up to 10 frames per second*3. Reliable low-light AF Low light won't prevent the 9 from focusing accurately. The image sensor's outstanding sensitivity leads to reliable detection and high AF precision down to light levels as low as EV-3* at the equivalent of ISO 100 with an F2.0 lens. * AF-S mode. Expand Flexible Spot When using Flexible Spot to precisely position the focus point, this function automatically shifts focus to one of the eight adjacent focus points if the subject moves away from the selected focus point, thus maintaining perfect focus. *1 With SSM or SAM lenses only. Phase detection or contrast detection AF can be selected via the "AF System" menu item. Focal plane phase-detection AF not supported for movie recording. Visit Sony's support web page for lens compatibility information. *2 Software update scheduled for release in May 2017. *3 "Hi/Mid" mode, electronic shutter. Maximum continuous shooting speed will depend on the lens used. AF in Focus Magnifier Bringing autofocus and focus magnification together for extra convenience and precision, it is possible to use autofocus while the selected focus area is magnified in the viewfinder and LCD monitor. You can even magnify the view after autofocus has been achieved for easier focus confirmation. This function is ideal for macro photography and other situations where focus must be precise. 18 19
