The world's smallestcamera with wide zoom range
Covering the range from wide-angle 24 mm to telephoto 720 mm, the HX99 is the perfect camera for everything from memorable travel photos to everyday snapshots. The ZEISS® Vario-Sonnar T* lens delivers superb image quality all across the zoom range, and the Clear Image Zoom feature allows further magnification of the subject (up to 1440 mm) while preserving high resolution.  24 mm  720 mm  1440 mm
Exmor R™ and BIONZ X™ deliver superb image quality
The HX99's image sensor — an 18.2 megapixel (effective) back-illuminated CMOS sensor — works with the advanced BIONZ X image-processing system to deliver superb image quality, even for fine textures and details. With a range of ISO80-6400 (expanded), even dimly lit scenes can be beautifully shot, while color-reproduction improvements produce natural-looking skin tones.
4K movies recorded with full pixel readout
The HX99 is the first in the HX-series to record 4K video (QFHD, 3840 x 2160 pixels). High-quality 4K video is achieved with a full sensor pixel readout, and no pixel binning - collecting approximately 1.6x as much information as is required. This oversampling effect results in images of outstanding resolution with reduced moiré and jaggies.
Continuous shooting at up to 10 frames per second
It's possible to perform high-speed continuous shooting at up to 10 frames per second for up to 155 shots. Even when image brightness changes during continuous shooting, the camera automatically adjusts to provide optimal exposure. Continuous-shot images can also be displayed, deleted, and protected in groups.
Eye AF feature for perfect portrait shots
The camera's sophisticated Eye AF feature can be activated to automatically detect and focus on the eyes of the main subjects in your shots. It rapidly and accurately detects eyes even under difficult conditions, such as when the subject is looking downward or when faces are backlit or dimly lit.
Fast Intelligent AF to capture decisive moments
The camera adopts Fast Intelligent AF using highly accurate contrast-detection autofocus with 0.09-second response. It achieves focus by minimizing wasted lens motion, predicting AF range and accelerating the lens drive, improving response so you can capture even more fleeting moments.
Control ring for advanced photography
The convenient lens-mounted control ring allows you to operate pro-style manual controls such as selecting shutter speed, aperture, and more for added creative control — so there’s no need to compromise your vision because of the camera’s compact size.
Clear, easy-to-operate OLED Tru-Finder™
The high-contrast OLED Tru-Finder is far brighter than conventional electronic viewfinders. It displays real-time preview and shooting information, so what you see on screen is exactly what you get in your shot. The viewfinder is easily retractable, for portability, safety, and convenience.
Image stabilization with Optical SteadyShot™
Designed for handheld shooting and when shooting at telephoto zoom settings, even with high magnification, the camera's Optical SteadyShot feature stabilizes the image and effectively reduces camera shake by relying on a high-performance gyro-sensor and a specialized algorithm. Because this is an optical function, image stabilization is performed without lowering resolution.  SteadyShot OFF  SteadyShot ON
Touch Pad AF
When using the viewfinder, use Touch Pad AF to shift focus smoothly and easily, simply by sliding your finger across the LCD screen.
Touch Focus and Shutter
With Touch Focus you can simply touch the LCD at the point of the image you want to focus on, for both still and video capture, so you can intuitively focus on subjects even at the edge of the frame without reframing. The shutter can also be operated by touching the LCD screen.
180° tiltable LCD screen for flexible composition
The high-resolution 3-inch type screen with tilt capability is perfect for taking selfies and framing low-angle shots. You can use it in various shooting positions for greater flexibility in capturing creative compositions.
If you lose track of a moving subject while framing with zoom, the Zoom Assist function makes it easy to find it again. Program it to the C (custom) button, then simply push and hold it to automatically zoom out, find and frame your subject again, then release the button. The camera quickly zooms back to the original focal length, so you can resume shooting the subject.
RAW format recording
In order to give users far greater control over the final appearance of their photos, the HX99 provides RAW-format image recording as an option. With this format all the data from the sensor is preserved, so exposure, brightness, white balance, and other aspects of the image can be easily adjusted using image-editing software.
High-frame rate HD video recording of fast-moving subjects
When you're shooting movies, you can capture fast-moving subjects with high-frame rate HD recording at up to 120p (NTSC) or 100p (PAL). This allows you to produce impressive slow-motion sequences during editing. The high bitrate, up to 100 Mbps, also ensures detailed images.
Proxy data recording for easier, faster editing and sharing
While recording full-resolution 4K video, the camera can also capture a low-bitrate proxy file that's lighter and easier to handle. This makes it easy to upload and share the images soon after shooting them, enabling easier online collaboration.
A firmer grip for steadier shots
The camera's grip is designed to better fit your hand, making it easier to hold in order to provide stability, despite the camera's compact size. It provides more stable framing of handheld shots and reduced camera shake, for steady shots even when held in one hand.
Lock-on AF for enhanced photo opportunities
Lock-on AF captures and continues tracking moving subjects. It automatically adjusts the AF target frame size to match the subject size, improves tracking performance, and helps you take full advantage of every photo opportunity.
Convenient on-location rating and sorting
Rate and protect your images in the field, with a convenient custom button assignment. Ratings, from 1 to 5 stars, can be reviewed when images are imported to your PC using PlayMemories Home™ or the new Sony Imaging Edge software, for fast sorting of even large image libraries.
Internal pop-up flash
The camera's built-in, manual pop-up flash feature enables various modes of flash photography. Slow Sync is useful for shooting atmospheric night portraits, Rear Sync lets you creatively express motion, and the Autoflash setting automatically determines whether the flash is necessary.
My Menu your way
With My Menu, you can register menu items for instant recall, and create custom menus. The menu screen has been redesigned, and you can make function assignments for up to 30 items to retool the camera interface according to your shooting preferences.
New LCD power-saving mode
With the camera body power switched ON, the LCD screen can be automatically switched OFF (either 2, 5, or 10 seconds after its last operation) to save power.
One-touch remote and sharing
With one-touch remote, a smartphone or tablet can function as a monitor and remote control. One-touch sharing allows easy transfers of photos or videos to an NFC™-enabled Android™ device for easy uploading and sharing. Just install the PlayMemories Mobile™ app from your device's app store, then touch the device to the camera to connect them. QR code compatibility allows connection with non-NFC devices.
Imaging Edge software suite from Sony
The Imaging Edge software suite can maximize image quality, improve production efficiency, and help you finely adjust RAW-based images. Use its “Remote” to remotely control shooting while monitoring scenes via live-view PC screen; "Edit" to develop RAW data into high-quality photos; and "Viewer" to view, rate, and select photos from a list of shots.
Geo-tag your images via Bluetooth®
With the Bluetooth® Location Information Link you can easily geo-tag your images – perfect when travelling. Simply pair your camera to a compatible smartphone with the PlayMemories Mobile app and your location data can be recorded together with each photo. The PlayMemories Home app can also be used on your PC to organize imported still images on a map.
