Sony a6400 Mirrorless Camera | Body Only

The Sony a6400 is a sophisticated APS-C-format mirrorless camera that combines a dependable design with impressive performance to enhance creativity. It offers a comprehensive range of photo and video functionalities, utilizing a tried-and-true sensor design, rapid and accurate autofocus capabilities, and intuitive operation. This camera serves as an excellent companion for documenting both daily occurrences and extraordinary events.

24.2MP APS-C Exmor CMOS Sensor and BIONZ X Processor

The 24.2MP Exmor CMOS sensor, designed in APS-C format, delivers exceptional image quality characterized by smoothness and subtlety, while maintaining low noise levels and high sensitivity across an ISO range of 100 to 32000, which can be further extended to ISO 102400 for optimal performance in low-light environments. This sensor incorporates a distinctive design that employs thin copper wiring, advanced circuit processing, and an improved front-end LSI, all of which enhance its light-gathering capabilities, minimize noise, and accelerate readout speeds, thereby benefiting video recording. Additionally, the synergy between the sensor and the BIONZ X processor enables a maximum continuous shooting speed of 11 frames per second with autofocus and auto exposure, or up to 8 frames per second when utilizing a silent shutter, while also supporting 14-bit raw file output for a broad range of tonal and color representation.

UHD 4K Video Recording in XAVC S Format

The device is capable of internally recording UHD 4K video at various frame rates, reaching up to 30 frames per second, while utilizing the entire width of the sensor. This recording employs 8-bit 4:2:0 color sampling and the 100Mbps XAVC S codec. Additionally, oversampled 4K recording is achievable, utilizing a 6K capture area within the Super 35 format to enhance detail. This method features full pixel readout without pixel binning, resulting in superior image quality with minimized moiré and aliasing effects.

The a6400 offers a wide range of customizable color and gamma settings, enabling users to modify parameters such as gamma, black level, knee, and color level, among others. It incorporates the same S-Log2 Gamma Curve utilized in high-end Sony Cinema cameras, which enhances the video signal by capturing up to 1300% more dynamic range compared to the conventional Rec. 709, thereby providing greater flexibility in post-production. Additionally, it supports HLG (Hybrid Log-Gamma) and the BT.2020 color space, allowing for recordings within an extensive color gamut. Alongside S-Log2, S-Log3 is also available, facilitating an effective 14-stop dynamic range and improved grading control in the shadow to mid-tone areas of the image. Furthermore, the camera supports high-resolution internal recording and offers uncompressed HDMI output, which allows for the connection of an optional external recorder for pristine 4K recording with 4:2:2 sampling.

The interval shooting mode is particularly well-suited for the creation of time-lapse films when utilized in conjunction with Imaging Edge software. Users can select intervals ranging from 1 to 60 seconds, enabling the recording of up to 9999 consecutive frames. Additionally, 4K video recording provides the capability to generate 8MP still images during playback by extracting a frame from the video and saving it as an individual file. The Slow & Quick (S&Q) mode permits videographers to capture Full HD video at designated frame rates between 1 and 120 fps. These configurations facilitate the ability to decelerate fast-paced action or accelerate scenes that unfold slowly.

4D FOCUS

Encompassing almost the entire sensor region, an advanced 4D FOCUS system integrates 425 on-chip phase-detection points in conjunction with 425 contrast-detection zones, allowing for accurate focusing in as little as 0.02 seconds. The concentration of focusing points provided by this hybrid autofocus system also facilitates High-density Tracking AF Technology, which excels at following moving subjects across diverse lighting environments.

Real-time Eye AF For Human

The Real-time Eye AF feature enables ongoing eye tracking during the capture of moving portraits. Users have the option to prioritize either the left or right eye, and this functionality remains effective even when the subject's face is partially obscured, illuminated from behind, or tilted downward. This technology allows for focus to be centered on the eyes of identified human subjects in portrait photography and is compatible with both AF-S and AF-C modes, applicable to both still images and video recordings.

Real-time Eye AF For Animals

The Real-time Eye AF for Animals feature facilitates the tracking of animals, enabling swift, accurate, and automatic detection and monitoring of their eyes with a simple half-press of the shutter button. This innovative functionality significantly enhances the photographer's likelihood of success when capturing images of wildlife or cherished pets at home, particularly in scenarios where achieving precise focus has historically posed difficulties.

Autofocus You Can Rely On

Lock-on AF ensures that focus remains on moving subjects by utilizing a customizable frame positioned over the intended subject. Expand Flexible Spot utilizes adjacent focus points to maintain focus on moving subjects, even if the initially chosen point loses clarity. The Focus Magnifier feature is available for achieving precise focus on intricate subject details. The rear touchscreen facilitates Touch Focus and Touch Tracking control, while the Touchpad Focus Control mode allows for intuitive use of the rear screen without diverting attention from the viewfinder. In addition to its autofocus capabilities, the a6400 incorporates a Peaking MF function, which enhances manual focus control by highlighting sharp edges of contrast, providing a more objective method for achieving sharp focus.

Body Design and Connectivity

The Tru-Finder 2.36m-dot OLED electronic viewfinder provides a luminous, high-resolution option for monitoring at eye level. Accompanying this is a 3.0" 921.6k-dot LCD touchscreen that can be tilted 180° upward or 74° downward, facilitating work from both elevated and lower perspectives. This screen features White Magic technology, utilizing an RGBW pixel arrangement to enhance brightness, making it suitable for use in bright daylight. The touchscreen interface allows for Touch Focus control, enabling quick selection of focus points, as well as a Touchpad function that permits smooth and intuitive focus point selection on the screen while viewing through the viewfinder.

The integrated 3.5mm microphone ports provide enhanced audio control during video recording. The NP-FW50 rechargeable lithium-ion battery included with the device is capable of approximately 410 shots per charge when utilizing the LCD screen, or 360 shots when employing the viewfinder. In addition to battery operation, the a6400 can be powered through a USB connection to a computer or mobile battery, which also facilitates battery charging. The built-in Wi-Fi feature allows for immediate sharing of images to mobile devices, enabling direct online sharing to social media platforms, via email, and to cloud storage services. Furthermore, NFC (Near Field Communication) support enables a one-touch connection between the camera and compatible mobile devices, eliminating the need for complex setup procedures. Once paired, the connected mobile device can display a live view image and remotely control the camera's shutter. Additionally, Bluetooth connectivity is available for acquiring location data.
