The Sony Alpha SLT-A57 SLR Digital Camera (Body Only) combines the image quality and control of a professional DSLR with the ease and efficiency of a point-and-shoot camera, resulting in a camera that is both versatile and affordable.

Using this fusion of technology, you will be able to create stunning visuals while using a straightforward interface and functionality. With a 16.1MP APS-C Exmor HD CMOS sensor, this camera is capable of capturing high-quality stills and video in low-light conditions while maintaining superb image quality.

It also has Translucent Mirror Technology for continuous autofocus monitoring, allowing you to capture crisp images and videos in full HD 1080p while shooting at up to 12 frames per second with confidence.

This improved performance is carried over into a number of features that are specially designed to capture the finest photographs possible without the need for you to be worried about specific camera parameters.

It is a unique option that automatically identifies portrait circumstances and produces balanced portraits depending on the qualities of your subject. Auto Portrait Framing is only available in Lightroom.

Additionally, it employs a variety of different modes, such as Face Detection, Smile Shutter, and Face Registration, and it automatically produces an appealing composition depending on where your subject is placed inside the frame, where they are looking, and how they are lighted.

When used in Auto Portrait Framing, Clear Image Zoom is a powerful tool that allows you to zoom in on the center of your image by up to two times without experiencing any obvious image deterioration.

Through the use of an improved Tru-Finder EVF and a high-quality tiltable LCD panel, you will have an easier time reviewing and monitoring your imagery. This viewfinder displays a variety of useful information within the display and also allows you to see how exposure settings, white balance tweaks, and other creative options will affect your photograph.

The LCD monitor has a resolution of 3.0 “It has a resolution of 921,600 dots, which provides sharp visuals during playback or in Live View. It can also be tilted up to 180 degrees and turned up to 270 degrees, allowing it to be used in a number of positions.

Translucent Mirror Technology is a term used to describe a type of transparent mirror.

Translucent Mirror Technology serves as the foundation of this camera, providing a sturdy platform from which many of the high-speed functions may be used with ease. In order to provide rapid and responsive actions, this technology automatically distributes light to both the image sensor and the autofocus sensor on a continuous basis.

Autofocus with 15 points of continuous coverage

The autofocus mechanism is able to continually monitor the image frame and adjust the focus swiftly and responsively due to the use of Translucent Mirror Technology. It is particularly handy when a crucial focus is required during video recording or when filming in continuous mode.

When identifying focus sites, it makes use of 15 points, including three cross sensors, to achieve a high degree of precision and speed. In low-light conditions and while following moving things, this focusing efficiency is even more impressive.

Continuous shooting at a rate of 12 frames per second

The Tele-zoom Continuous Advance Priority AE mode allows you to record at up to 12 frames per second while magnifying the center of your image by 1.46x while recording at up to 12 frames per second. This cropping reduces the resolution of your photograph to 8MP and puts your subjects closer together for tighter compositions. The maximum frame rate when photographing at full resolution is 10 frames per second.

Exmor APS HD CMOS Sensor with 16.1 Megapixels

In addition to providing excellent image quality, the Exmor HD CMOS sensor with 16.1MP resolution and APS-C format offer enhanced low-light performance. Using this sensor, you may capture images at ISOs ranging from 100 to 16000 while also efficiently minimizing noise at greater sensitivity levels.

This camera’s mix of high sensitivity and low noise makes it excellent for action photography, whether it’s indoors or out in the nighttime.

BIONZ Image Processor is a digital image processor.

The upgraded BIONZ image processor makes use of advanced algorithms to achieve rapid speeds and performance, greatly lowering write times and, in general, speeding up the entire process of using your camera, as seen in the video below.

Because of the enhanced power provided by this processor, it is possible to achieve more noise reduction and more richly defined gradations over the whole dynamic range of the image.

Full-HD video recording is available.

It is possible to record in full HD 1080p with this camera, which also makes use of the high-speed Translucent Mirror Technology for continuous focusing, even when utilizing the Live View mode to watch your shooting.

The AVCHD version 2.0 (Progressive) format is employed, which enables the recording of 60 frames per second, resulting in exceptional clarity and detail in motion.

Additionally, the 24p frame rate is enabled, allowing you to produce movies that have a more cinematic sense to their presentation. This slower pace is the same as that utilized in movie theater playback, and it provides your movies a more cinematic appearance and feels by virtue of their intrinsic cinematic nature.

Fully manual shooting modes, which give you complete control over your video recording, give you even more control over your aperture and shutter speed.

Auto Portrait Framing is a feature that allows you to frame your portrait automatically.

Auto Portrait Framing automatically produces compositions centered on your portrait subjects and artistically crops your image based on the rule of thirds, the location of your portrait within the frame, the exposure of your subject, and the direction in which he or she is gazing.

Face Detection, Smile Shutter, and Face Recognition modes are used in conjunction with Auto Portrait Framing to provide the finest portraiture possible in a time-efficient manner while still maintaining high-quality standards.

Because of these factors, this mode makes use of the Clear Picture Zoom feature and automatically produces a second image file based on them.

Zoom in on a clear image

Because of the use of By Pixel Super Resolution Technology, this camera is capable of zooming in on the center of your image up to 2.0x with little to no perceptible decrease in image quality.

This complicated set of algorithms effectively doubles your zooming range, giving you a genuine possibility to capture spectacular photographs from far distances without sacrificing quality.

Viewfinder with an electronic display (Tru-Finder)

In addition to having a high resolution of 1,440K dots, the Tru-Finder EVF also has a 100% field of vision and a wide viewing angle of 31.9°, making it an excellent choice for professional photographers. This finder shows essential image information, like as exposure settings and mode selections, on the screen.

Additionally, this finder has Shot Result Preview, which allows you to see how exposure control, white balance adjustments, and other creative features will affect your image before you take an exposure. The finder magnification can be adjusted between 1.04x and 0.97x, allowing you to view the full-frame while wearing glasses. It also has an adjustable finder magnification.

Xtra Fine LCD Display

The back 3.0 is a 3.0 “Its 7.6cm LCD screen is equipped with Sony’s TruBlack technology, which enhances clarity and resistance to reflections. With a 921,600-dot resolution, it provides crisp, colorful visuals while analyzing photographs or watching your recording while using Live View, which is particularly useful for shooting in low light.

A Shot Result Preview option is also available on the display, which allows you to see the impact of your camera’s settings before you take the exposure. In order to provide even broader viewing options when filming, the screen can be tilted up to 180 degrees vertically and rotated up to 270 degrees horizontally.

When looking from challenging angles or under bad lighting circumstances, the range of motions and reflection protection provide a broad variety of options.

Image Stabilization INSIDE the Camera Using SteadyShot

This camera has Sony’s SteadyShot picture stabilization technology, which provides image stabilization within the camera. Shake compensation can be achieved by decreasing camera shake at the camera level, resulting in shutter speed increases of up to 2.5-4.5 stops. This technology is compatible with any Sony Alpha lens that has been developed.

Buttons that can be customized

Using two buttons, you may manually assign up to 24 distinct functions, giving you greater freedom over your personal shooting requirements. The AEL and ISO buttons may be customized to allow one-touch access to other settings, such as Drive Mode and Flash Mode, by holding them down for a few seconds.

Panorama with a sweep

It’s easy to make panoramas using this mode. Simply move your camera around the area, then press a button, and the camera will automatically stitch together numerous shots into a single seamless panoramic file.

Sweep Panorama in 3D is also supported, and it works in the same way as the regular panorama, except that it automatically produces a stereoscopic picture for 3D viewing on an HDMI-compatible 3D screen.

Auto High Dynamic Range

During the use of this mode, three distinct bracketed exposures are taken at the same time and then automatically combined into a single file. Consequently, this file has the widest variety of tones in the highlights, mid-tones, and shadows of any other file.

Because it does not necessitate the use of a tripod, this mode is more convenient than standard high dynamic range capture because it reduces the entire process to a simple in-camera function.

Multi Frame NR and Hand-held Twilight, which are conceptually similar to HDR photos, are equipped with noise reduction technology that automatically combines six separate shots into a single file, resulting in a decrease in the noise of up to two ISO levels.

As soon as you have determined your chosen settings, you may proceed to capture photographs in extremely low light conditions with confidence. In order to deliver a boost in brightness without the additional noise that comes with higher sensitivity levels, the camera mixes these six exposures.

Because the initial exposure time is shorter as well, you may easily handhold for photos that are crisp independent of the surrounding illumination.

Flash Memory Built-In

The built-in pop-up flash has a guide number of 32.8′ / 10m at ISO 100 and has a range equivalent to an 18mm wide-angle lens when used in conjunction with the camera.

Auto Mode, Scene Selection, and Exposure Mode are all superior.

These modes all assist in making the process of obtaining the optimum exposure possible as simple as possible, enabling you to concentrate on the subject you are photographing rather than the camera settings.

Superior Auto mode intelligently recognizes the situation you are capturing and changes the camera settings to get the best possible pictures. Also capable of triggering continuous shooting modes for moving subjects and Auto HDR mode if the dynamic range of a single frame is greater than the dynamic range of a continuous shooting mode.

Scenario Selection gives you a little more control over your photography by allowing you to choose the sort of scene you want to take and then have the camera settings modified accordingly. You may also choose the sort of image you want to capture and the exposure mode will automatically apply adjustments in-camera to compensate for the difficulties of that particular circumstance.

Effects on Photographs

A wide range of visual effects is offered for in-camera image processing as well as for creative applications such as video editing.

Some of these effects are HDR Painting, Soft Focus, Miniature (in both color and black and white), Soft High-key (in both color and black and white), Pop Color, Partial Color (in both color and black and white), Rich-tone Monochrome, Toy Camera, High Contrast Monochrome, Posterization (in both color and black and white), and Retro Photo.
