Matching its high-quality image capabilities is a well-rounded physical structure that is completely weatherproof, allowing it to be used in a variety of challenging environmental circumstances. In order to provide clear, uncompromised viewing, a quad-VGA OLED Tru-Finder with an amazing 3.686m-dot resolution and 120 fps refresh rate is included.
This allows for crisp, bright, and smooth viewing at eye level. As an alternative, a 3.0 “Working from high and low angles is made easier by a 1.44m-dot tilting touchscreen LCD, which has 1.44 million dots. Dual SD memory card ports, a customizable menu system, and a range of physical control knobs round out the camera’s user-friendly design, while built-in Wi-Fi and Bluetooth allow for wireless picture sharing and remote camera control from connected mobile devices, among other features.
Exmor RS Stacked CMOS Sensor with 24.2MP Resolution in Full-Frame Mode
The a9 is equipped with a 24.2MP Exmor RS stacked CMOS sensor, which is a first for a full-frame camera and provides remarkably fast readout speeds, allowing for up to 20 frames per second continuous shooting and UHD 4K video recording.
With its back-illuminated architecture, the sensor achieves high sensitivity up to an extended ISO 204,800 while also exhibiting decreased noise, resulting in clear image clarity in a range of lighting situations.
Additional advantages of shooting in 14-bit uncompressed raw files include improved color accuracy and increased post-production flexibility, among other things.
BIONZ X Image Processor is a high-performance image processor.
The BIONZ X image engine, which works in concert with the stacked CMOS sensor, guarantees that processing rates are fast enough to keep up with fast-paced shooting scenarios.
Shooting continuously at up to 20 pictures per second for up to 362 consecutive JPEGs or 241 raw frames is possible, and the camera has a maximum electronic shutter speed of 1/32,000, which is ideal for freezing fast-moving subjects or working in high lighting settings.
As a result of the fast recording capabilities, an equally quick AF/AE metering system has been developed, which operates at 60 times per second to continually review and evaluate and evaluate the scene in order to lock onto and follow moving subjects.
Aside from that, the usage of an electronic shutter allows for completely blackout-free monitoring of moving subjects through the electronic viewfinder, which allows for more precise compositions of moving subjects.
AF with 693 phase-detection points
Focusing is accomplished quickly and precisely in a range of lighting circumstances thanks to the inclusion of 693 phase-detection points as well as 25 contrast detection regions spread across 93 percent of the picture area.
Sensitivity is as low as three stops below the ISO sensitivity of the camera. With the high density of focusing points provided by this hybrid AF technology, High-density Tracking AF Technology is enabled, which is capable of tracking moving subjects in a range of lighting situations.
The use of phase-detection points also permits the use of A-mount lenses with full continuous AF/AE tracking compatibility when using the optional LA-EA3 or LA-EA1 lens mount adapters, which are available separately.
For improved accuracy, the apt focus system is also capable of a variety of focusing functions.
These include Lock-on AF, which maintains focus on moving subjects throughout the use of a configurable frame that is placed over the desired moving subject; and Expand Flexible Spot, which employs neighboring focus points to maintain focus on moving subjects even if the originally selected point loses focus.
Additionally, Eye AF, which can be used to focus on identified subjects’ eyes for portraiture and is available in both AF-S and AF-C modes, may be used to base focus on recognized subjects’ eyes. When focusing on minute subject details, autofocus can be utilized in concert with the Focus Magnifier feature to achieve critical focus on the topic at hand.
Beyond autofocus, the A9 is equipped with an additional Peaking MF function, which is designed to assist in the manual focus control by highlighting strong edges of contrast for a more objective way of achieving fine focus.
5-Axis SteadyShot Image Stabilization INSIDE the camera
The powerful a9 is equipped with a 5-axis SteadyShot INSIDE image stabilization technology that adjusts for five distinct forms of camera shaking that can occur while shooting stills and video with the camera in hand. The ability to utilize any lens, even adapted lenses, for important images without encountering blur due to camera shake is a huge advantage for photographers.
When working with longer focal lengths, the system will compensate for pitch and yaw corrections automatically. The incorporation of horizontal and vertical shift correction will, on the other hand, be beneficial for macro and high-magnification pictures.
The roll compensation will be beneficial to photographers of all shooting types. No matter if you are using third-party lenses and adapters or lenses with built-in optical stabilization, all five axes of stabilization will always be active and working properly.
UHD 4K video recording in the XAVC S format is supported.
It is possible to record UHD 4K movies internally at multiple frame rates up to 30 frames per second. Based on the Super35mm recording area and effective 20MP (6000 x 3376) resolution, 2.4x oversampling provides greater detail, and full pixel readout, which means no pixel binning, is possible for higher quality imagery with reduced moiré and aliasing.
It is also possible to record in full HD 1080p at frame rates of up to 120 frames per second, and both resolutions make use of the 100 Mbps XAVC S codec, which is stored behind an MP4 wrapper with 4:2:0 sampling. The high-speed, 120-frame-per-second recording also allows for 4x and 5x slow-motion video recording at frame rates of either 30p or 24p, depending on the frame rate setting.
An optional external recorder capable of clear 4K recording with 4:2:2 sampling can be used in conjunction with the high-resolution internal recordings made possible by the uncompressed HDMI output, which is also available.
While recording a 4K video, users will have the option of creating 8MP still images during playback by capturing a frame grab from the video and saving it as a separate file.
Motion in both slow and rapid motion
Using the S&Q mode, you may have greater control over your video capture capabilities by using a number of different frame rates that are accessible in the S&Q mode. Shooters will be able to capture Full HD footage at one of two frame rates: one step between 1-120 frames per second or one step between 1-120 frames per second.
These options will allow you to slow down fast-moving action while simultaneously speeding up a slow-moving scenario. This parameter is also switchable between NTSC and PAL.
Zebra Function Has Been Improved
In high-contrast scenarios, an increased Zebra function is particularly well suited for aiding in the monitoring of exposure levels. Video signal level goals may be set anywhere between 0 and 109, and particular ranges can be defined to facilitate adjusting the exposure level easily.
Setting the Time Code and the User Bits
A time code may be used to record hours, minutes, seconds, and frames on picture data for more exact editing, while the User Bit function can record the date, time, and scene number to help in the editing of video from various cameras when putting together footage from numerous cameras.
