Sony Alpha ILCE-6400A + Sigma 12mm f1.4 DC (C)

Sony Alpha ILCE 6400

With the Sony Alpha 6400, there are no longer any limits to your creative imagination. The Alpha 6400 impresses with its high performance and modern functions such as AI-based AF with real-time eye detection, high-precision real-time tracking, high-speed continuous shooting function and 4K HDR (HLG) video recording.

The Sony Alpha 6400 impresses with its first-class image quality, new autofocus, 4K video and up to eleven continuous shooting frames per second.

425 phase detection autofocus points

The high focus point density covers around 84% of the image area, making it easier to capture the subject.

Continuous shooting with AF/AE at up to 11 frames per second

Thanks to the fast internal processing and large buffer memory, you won't miss a thing. Capture moments with minimal display delay at 11 frames per second in After View and 8 frames per second in Live View and continuous shooting with up to 116 JPEG (standard) or 46 compressed RAW shots.

Quiet continuous shooting at up to 8 frames per second

When absolute silence is required when shooting, you can shoot at up to 8 frames per second without any noise - with AF/AE tracking activated, even in AF-C mode, with AF with eye detection in real time or real-time tracking.

The newly introduced AI-based subject detection technology processes a wealth of data and can even detect and track fast-moving subjects.

Precise eye detection

The optimized AF with real-time eye detection reliably detects human faces and focuses precisely on the eyes - without any special settings, simply by pressing the shutter button.

Continuous eye tracking

When AF-C is activated, AF with eye detection reliably focuses on moving images in real time - even if part of the face is obscured, backlit or looking down.

Select the left or right eye of your subject

Select "Left Eye", "Right Eye" or "Auto" before shooting so you can concentrate on the composition. Assign custom buttons to these options for quick switching during shooting.

Reliable focus with real-time tracking

Keeping subjects in focus at sporting events and other moving images can make or break your ability to capture an important, dramatic moment.

Focusing with new subject detection algorithm

A newly developed subject detection algorithm processes spatial color, distance (depth), pattern (brightness), face and eye information in real time and at high speed.

Eye tracking and seamless transitions

The tracking system captures the entire body of a person in motion from a greater distance. The focus area switches seamlessly between the face and eyes depending on the subject conditions.

Simple touch tracking

If touch tracking is configured in the menu, you can select the subject simply by touching the monitor. The camera then tracks the subject automatically for both photo and film recordings

. Thanks to the large sensor and the modern image processor, you can capture any subject in ultra-sharp, natural colors - even in difficult lighting conditions.

24.2 megapixel sensor and optimized image processor

The APS-C sensor is equipped with copper wires and optimized circuit processing to improve light capture. In combination with the image processor, you achieve a high image resolution and a natural reproduction of structures.

Sharp images even in low light

Noise reduction enables sharper images even when shooting with high sensitivity in the dark. The basic ISO sensitivity has been increased to ISO 32000 (with an extended ISO sensitivity up to ISO 102400 for photo shooting). This allows you to achieve good results in the frequently used medium to high sensitivity range.

Natural-looking, realistic images

Image processing algorithms similar to those used in full-frame cameras now enable more natural color reproduction.

Full pixel readout without pixel binning, high-resolution 4K video recordings, HDR (HLG) and S-Log/S-Gamut as well as slow motion and time-lapse recordings: The α6400 offers a wide range of functions that expand your creative possibilities when filming.

Time-lapse movies

The camera includes a newly introduced interval shooting function, i.e. continuous shooting with an interruption between 1 and 60 seconds between photo shots. This can be used to create time-lapse movies on a PC using the Viewer app, which is part of the Imaging EdgeTM desktop applications.

Practical vlog functions

The 180-degree swivel LCD display is useful for selecting the image section when recording vlogs. In addition to the socket for an external microphone, an optional XLR adapter (sold separately) can also be used for the audio track, allowing the use of professional microphones for higher audio quality.

The 3.0-inch LC display, which can be tilted 180 degrees, not only shows the subject in front of you, but also makes a range of camera functions accessible via intuitive touch functions.

Seamless focus area selection via touchpad

The touchpad function allows you to move the focus seamlessly while looking through the viewfinder. Simply drag your finger across the monitor to the point you want to focus on.

Touch focus and touch shutter

Touch focus allows you to change the focus position simply by touching the monitor and even move it to the edge of the image. And with the touch shutter, you can focus and release the shutter with just one touch.

Activating real-time tracking via touch tracking

With the touch tracking function, you simply touch the monitor to activate real-time tracking for photo or video recordings. The camera then immediately focuses permanently on the subject.

Sigma 12mm f1.4 DC © For Sony E-mount

The Sigma 12mm F1.4 DC Contemporary is an ultra-wide-angle fixed focal length lens with a focal length of 12 mm and the widest angle of view of any F1.4 lenses for APS-C cameras.*1 Thanks to its state-of-the-art optical design, the lens delivers high resolution and captures wide starry skies and landscapes with exquisite detail at wide open aperture.

Outstanding optical performance across the entire image

Three double-sided aspherical lenses and two SLD glass elements are effectively arranged to achieve high optical performance at a wide-open aperture of F1.4. Sagittal coma flares are also well corrected, ensuring clear, sharp images from edge to edge, even in starry night scenes where fine detail and sharpness are crucial.

Compact and lightweight design for excellent portability

The effective placement of double-sided aspherical elements enables a compact and lightweight design despite the ultra-wide angle and large aperture. This ensures high mobility and makes the lens easy to transport for travel and outdoor shooting. The lens is also compatible with camera grips and gimbals. Photographers and filmmakers can thus effortlessly enjoy the unique dynamics of a 12 mm F1.4 lens.

Smooth, responsive autofocus with stepping motor

Fast and precise autofocus is achieved by driving a lightweight focus lens with a stepping motor that enables precise control. Whether for still images or videos - the Sigma 12mm F1.4 DC Contemporary captures important moments at lightning speed. In addition to everyday snapshots, the lens offers high tracking performance in moving scenes, enabling high-quality video productions.

Minimal focus breathing

Focus breathing is suppressed, minimizing changes in the angle of view due to focus shift and enabling smooth, natural-looking focus pulls when recording video.

Aperture ring with various functions

Equipped with an aperture ring for intuitive control of the aperture. The Canon RF mount version has a control ring instead of an aperture ring, enabling functions to minimize flare and ghosting

. Designed to minimize flare and ghosting

By using the latest simulation technology, flare and ghosting have been largely eliminated so that the lens delivers rich, high-contrast results in all conditions.

Dust and splash resistant structure*1 / water and oil repellent coating

In addition to a dust and splash resistant structure *1, the front of the lens is coated with a water and oil repellent coating so that the lens can be used safely in harsh outdoor environments.

*1 The product is dustproof and splashproof, but not waterproof. When using the lens near water, etc., make sure that it is not splashed with large amounts of water. Water ingress can cause serious malfunctions and make the lens irreparable
