Sony a7

Incorporated into the Sony Alpha a7 Mirrorless Digital Camera is a full-frame Exmor CMOS sensor housed in an E-mount body, which provides the light gathering capability and detail-rich imaging of a full-frame sensor in a compact, lightweight, and versatile mirrorless, interchangeable lens camera system.

The 24.3MP sensor, which has a normal ISO sensitivity range of 100-25600, produces high-resolution photographs while also being effective in low-light conditions. In addition to fast processing and operation speeds such as 5 frames per second burst shooting, the new BIONX X image processor incorporates front-end LSI (large-scale integration) to improve the early stages of image processing, resulting in more natural details and richer tones in the images captured. The detail supplied by the sensor is preserved in the 14-bit RAW output.

Using a combination of a phase-detection and contrast-detection autofocus mechanism, the camera achieves great speed and accuracy while yet maintaining a small body size and weight.

Additionally, it has multipoint, center-weighted, and zone focusing capabilities that contribute to its functionality, and the manual focus assist may be adjusted for shooting zones in either full-frame or APS-C format, depending on the situation.

The new Eye AF Control feature delivers very accurate eye identification for photos that set the focus precisely on the subject’s eye, even when the subject is partially turned away from the camera.

It is possible to capture video in full HD 1080 resolution at frame rates as fast as 24p/60i/60p using both AVCHD and MP4 codecs. Video may be recorded off-camera in its native uncompressed format using an HDMI connection, and both built-in and external stereo recordings are possible.

Watching still photos on an ultra-high-definition 4K display through HDMI and wireless output is possible. The 3.0″ tiltable LCD features a 921.6k-dot resolution and is equipped with WhiteMagic technology, which improves vision in bright conditions.

A high-contrast 2.4M OLED electronic viewfinder with a wide viewing angle and 100 percent coverage is included, as is the same 3-lens optical system used in the Sony a99 DSLR.

Integrated Wi-Fi and NFC capabilities make it simple to share photographs wirelessly and operate the camera from mobile devices such as smartphones and tablets. Remote control through a USB connection allows for still photo alteration control as well as video capture control, which has just been added.

In order to allow for fast setting changes when needed, the Quick Navi Pro interface system may display all camera modifications on the LCD screen.

Additionally, as an E-mount full-frame camera, the Alpha a7 is compatible with all current APS-C size E-mount lenses in APS-C Crop Mode, as well as the new Zeiss and Sony G-series full-frame lenses. The advanced Sony Multi-Interface shoe expands compatibility options for flash, microphone, and other accessories.

Lens mount adapters with a tripod mount are also available to allow the use of A-mount lenses on E-mount cameras, and an optional dedicated battery handle allows for secure prolonged shooting and vertical orientation stability while shooting in portrait mode.

Digital Camera with Full-Frame Sensor and Compact Mirrorless Design

When combined with the tiny and lightweight form of an E-mount mirrorless camera, the Sony Alpha a7 achieves the photography capabilities of a full-frame while maintaining the ease and adaptability of mirrorless.

Sensor with 24.3 Megapixels (Exmor CMOS)

In addition to its 24.3 effective megapixels, the Exmor CMOS sensor creates high-resolution, low-noise photos that have rich tonal gradation and are sensitive to low light. When using the Alpha a7, the standard ISO range is 100-25600.

BIONZ X Image Processor is a high-performance image processor.

The new BIONZ X image processing engine, which incorporates additional high-speed processing capabilities, reproduces textures and details in real-time.

When used in conjunction with front-end LSI (large scale integration), which speeds the early processing steps, it allows for more natural details, more realistic pictures, richer tonal gradations, and reduced noise, regardless of whether you are shooting still photos or videos.

Autofocus with Hybrid Technology is quick and accurate.

It combines fast phase-detection autofocus with precise contrast detection autofocus, and it has been made even faster because of an improved Spatial Object Detection algorithm, which has been improved even more.

Contrast-detection autofocus with wide coverage fine-tunes accurate focusing after phase-detection autofocus with 117 tightly spaced phase-detection AF points quickly adjusts the lens to bring the subject close into focus.

Up to 5 frames per second Shooting in a Continuous Loop

When shooting at 5 frames per second in Speed Priority Continuous Shooting Mode, you can catch action photos and that elusive ‘perfect’ moment. This is made possible by the new quicker and more accurate AF tracking made possible by Fast Hybrid AF.

The Alpha a7, in contrast to the Alpha a7R, features a Hybrid Focus technology, which allows for quick focusing and frame rates for photographers who value performance speed over all else.

Affordability in conjunction with Sony’s E-mount lenses and the company’s new full-frame lenses

The Alpha a7 maintains its tiny and lightweight design while being completely compatible with Sony’s current APS-C E-mount lens system as well as the new range of E-mount compact full-frame lenses from Carl Zeiss and Sony’s flagship G-series lenses.

Tilt LCD Monitor with a screen size of 3.0″

The tiltable 3.0″ Xtra Fine LCD Display, with a 921.6K-dot resolution, makes it simple to picture from low or high angles since it can be adjusted up to 84° and down to 45° in each direction. The use of WhiteMagic technology significantly improves visibility in strong sunlight.

The big display produces brilliant-quality still photographs and videos while also making focussing and other operations simple and straightforward.

Electronic Viewfinder with 2.4 million dots on an OLED display

The viewfinder, which uses a three-lens optical system, accurately depicts what will appear in your video, including the impact of your camera settings. You’ll like the rich tone gradations and enhanced contrast.

A wide viewing angle and high-end features such as 100 percent frame coverage make it possible to compose at the level of the eyes in a pleasant and steady manner.

24p/60i/60p Full HD Movie with Uncompressed HDMI Output in 24p/60i/60p

The Alpha a7 is capable of recording AVCHD codec frames at super-smooth 60p, regular 60i, or cinematic 24p resolutions in-camera. Additionally, the MP4 codec is available for smaller files that may be uploaded more easily to the web.

Additionally, it is able to capture Full 1080 HD uncompressed clean-screen video files to external recording devices through an HDMI connection at frame rates of 60p and 60i, respectively.

Wi-Fi and NFC capabilities are built-in.

Wi-Fi and NFC control have made it easier to connect with smartphones for One-touch sharing and One-touch remote control functions. In addition to Wi-Fi connectivity for connecting to smartphones, the Alpha a7 also offers NFC (Near Field Communication), which allows for the transmission of photographs to Android smartphones and tablets without the use of a cable.

Users merely require touch devices to connect; there is no need for a complicated setup. When utilizing Smart Remote Control, a function that allows shutter release to be controlled by a smartphone, connected to the smartphone may be created by merely tapping two compatible devices together on the screen.

Direct Access Interface (DAI) is a type of interface that allows direct access to a computer.

You can quickly confirm settings and make adjustments without having to go through several menus with Quick Navi Pro since it displays all important shooting choices on the LCD screen of the camera. When shooting possibilities present themselves, you’ll be able to respond quickly and effectively with the appropriate settings.

Controlling the AF with the eye has been improved.

Because of the incredibly precise eye recognition that can prioritize a single pupil, even when photographing a person who has partially turned away from the camera with a short depth of field, the face will be clearly focused.

When focus has been achieved on the priority eye, a green frame appears above the eye to provide quick confirmation. It is possible to employ eye autofocus when the function is given to a customisable button, allowing users to activate it instantaneously depending on the situation.

RAW Output at 14 bits

The Alpha a7 produces 14-bit RAW picture data of exceptionally high quality, which is produced by the camera. During the 14-bit A/D conversion process, this data is used to retain the fine detail captured by the image sensor during the capture phase.

When created with Sony’s Image Data Converter RAW developing software, these photographs exhibit very high levels of photographic expressiveness and gradation, as well as a wide range of tones.

Remote Control with Video Capture Control that is wired

Remote Camera Operate allows you to control your Alpha a7 from your computer through a USB connector, which is included with the camera. It has been upgraded to provide the ability to control video capture.

A shoe with a variety of interfaces

Because of the sophisticated Multi-Interface Shoe, the Alpha a7 is substantially more compatible with Sony digital imaging accessories including flash units, microphones, lighting, and displays. This greatly increases the possibilities of your picture and video shooting.
