Zoom Lens Kit: The Sony SLT-A57K α (alpha series) DSLR
camera kit contains the SLT-A57 camera body, and the SAL1855 DT18-55mm
F3.5-5.6 SAM 3x zoom lens, along with a rechargeable battery, adjustable
neck strap, USB cable, and software on CD-ROM. The camera is compatible with
Sony A-mount lenses.
Translucent Mirror Technology: The A57 features Translucent Mirror Technology, which directs light to both the image sensor and the Phase Detection AF sensor simultaneously. This allows the camera to focus and capture the image at the same time. Since the mirror never moves, the time needed to raise and lower the mirror is eliminated.
Tiltable 3" LCD Screen: The A57 uses a 3" TFT Xtra Fine LCD screen with 921,600 dots. The TruBlack screen has a special resin layer to suppress internal reflections to increase contrast. The brightness of the LCD monitor is automatically adjusted to surrounding lighting conditions for best visibility. The LCD monitor can be tilted upward 150°, downward 180° and rotated 270° for best visibility when shooting at difficult angles.
0.46" Electronic Viewfinder: The 0.46" Xtra Fine electronic color viewfinder has
1,440,000 dots, and provides approximately 100% field of view. The brightness can be manually or automatically adjusted in 3 steps. The built-in diopter lets you adjust the viewfinder image to your individual eyesight. If you're using the electronic viewfinder to frame your shots, the LCD turns off automatically when you bring the camera up to your eyes.
Display Options: You can choose how much information appears in the viewfinder and LCD monitor. There are four options: Display all information, No display information, Digital Level Gauge, and
Graphic Display. The digital level gauge indicates whether the camera is level in both horizontal and front-back directions. The indicators turn green when the camera is level in one of the directions. The histogram displays the luminance distribution that shows how many pixels of a particular brightness exist in the picture.
Live View: The A57's Live View lets you use the LCD screen and Electronic Viewfinder to frame your photos as you shoot. The Live View image will provide an accurate preview of your photo, including the white balance, focus, depth of field, exposure, and framing. In addition, the on-screen displays will keep you informed on all your settings and recording information.
Image Sensor: The SLT-A57 features an APS-C-sized Exmor HD CMOS image sensor (23.5 x 15.6mm). It has approximately
16.7-million total pixels and 16.1-million effective pixels.
Still Image Recording Formats: Still images are recorded in JPEG file format in Standard and Fine compression rates. You can choose to shoot in 3:2 or 16:9 aspect ratio, and in large, medium, and small image sizes. You can also record still images using the RAW format, which is uncompressed with no processing performed in the camera. RAW images must be transferred to a computer for processing, editing, and printing using the supplied Image Data Converter SR software. You can select the following image sizes:

Dual Media Options: The A57 camera accepts two types of media for capturing still images: Memory Stick PRO Duo (including Memory Stick PRO-HG Duo), and SD, SDHC, and SDXC Memory Cards. The maximum number of images that can be recorded on a memory card formatted with this camera varies slightly between the two types of media.
Clear Image Zoom: Clear Image Zoom, powered by Sony's By Pixel
Super Resolution Technology, increases the effective focal length of the
lens by up to 2x by digitally magnifying the center of the image.
SteadyShot INSIDE In-Camera Image Stabilization: The SteadyShot INSIDE in-camera image stabilizer shifts the image sensor to compensate for camera shake without sacrificing image quality. The compensation effect is equal to 2.5 to
4.5 shutter speed steps, giving you more creative freedom when shooting in low light. And, because it is integrated into the camera body, SteadyShot INSIDE technology works with all compatible α (alpha) system lenses.
Eye-Start Auto Focus: The camera features the Eye-Start Auto Focus system, which begins precision auto focus adjustments the moment you raise the camera to your eye. This feature can be turned off in the menu, if desired.
15-Point AF System: The A57's high-performance auto focus system uses 15 focus points to deliver fast and precise focusing. It has a predictive focus control to automatically calculate the position of fast-moving subjects. You can choose from the following Auto/Manual Focus Modes:
- AF (Auto focus) Mode: You can select between 3 modes:
- Single-Shot AF: The camera focuses and the focus is locked when you press the shutter button halfway down.
- Continuous AF: The camera continues to focus while the shutter button is pressed and held halfway down.
- Automatic AF: This mode automatically switches between single-shot AF and continuous AF depending on the movement of the subject.
- AF (Auto focus) Area: You can select between 3 settings:
- Wide: The camera determines which of the 15 AF areas is
used in focusing.
- Zone: You can choose the zone for which you want to activate the focus from among left, right, or center.
- Spot: The camera uses the AF area located in the center area exclusively.
- Local: You can choose a local focus area from the 15 areas using the controller.
- Object Tracking: When Object Tracking is enabled, the camera allows you to select a subject to be tracked while it moves through the frame. The subject remains in focus until you press the shutter release.
- Manual Focus: When it is difficult to get the proper focus in auto focus mode, you can adjust the focus manually. This mode allows you to set the distance of a subject by switching to MF on the lens and rotating the focusing ring to achieve a sharp focus.
Face Detection/Smile Shutter: The camera can detect human faces, and adjusts the focus, exposure, performs image processing and adjusts flash settings for best results. Faces can be registered, and priority given to those faces over others in the frame. Up to 8 faces can be detected and/or registered. When the Smile Shutter feature is enabled, the camera will automatically release the shutter when a slight, normal, or big smile is detected.
Focus Lock: If a subject is off-center and outside of the AF area, you can lock the focus of the camera.
AF Illuminator: When you press the shutter button halfway down a red illuminator is emitted until the focus is locked. Under dark lighting conditions or when you shoot a low contrast subject, the AF illuminator allows the camera to focus more easily on the subject.
Drive Modes: The camera offers the following shooting modes:
- Single Shooting: Default setting for standard picture taking.
- Continuous Shooting: At full 16.1MP resolution, the camera
can record up to 10 frames per second. Tele-zoom High Speed shooting
captures the center 2/3 of the image sensor (8.4MP) and can record up to 12
fps continuously. Maximum number of continuous shots is as follows:
- Tele-zoom High Speed: 23 (fine), 25 (standard)
- Continuous Priority AE: 23 (fine), 27 (standard), 21 (RAW), 18
- Self-Timer: You can set the camera to two different self-timers:
- 10 Second: After you press the shutter button, the shutter will be released about 10 seconds later. This is convenient when the photographer wants to appear in a photo.
- 2 Second: After you press the shutter button, the shutter will be released about 2 seconds later. This is convenient to reduce camera-shake.
- Bracket Shooting: Bracket shooting allows you to shoot 3
images, each with different degrees of exposure. When Single Bracket is
selected, the shutter button is pressed for each shot one-by-one. White
Balance Bracket shooting lets you record three images, each with the white
- Remote Commander: You can shoot using the "SHUTTER" or "2SEC" buttons on the optional RMT-DSLR1 Wireless Remote Commander. Using the Remote Commander reduces camera shake and continues the exposure without pressing and holding the shutter button.
Shooting Modes: The top-mounted Mode Dial lets you select from the following
- iAuto (Intelligent Auto): This mode allows easy shooting with settings adjusted automatically.
- Flash Off: Same as Intelligent Auto, but without use of the
- iAuto+ (Superior Auto): The camera recognizes and evaluates the shooting condition and sets the appropriate settings automatically. The camera saves one appropriate image by combining or separating images as necessary.
- Scene Selection: You can select an appropriate mode for the subject or the shooting conditions to allow you to shoot the image with a suitable setting for the subject:
- Portrait: blurs away backgrounds and sharpens the subject; expresses skin tones softly
- Sports Action: for shooting moving subjects outdoors or in bright places.
- Macro: for shooting close subjects such as flowers, insects, dishes, or small goods.
- Landscape: shoots the entire range of scenery in sharp focus with vivid colors.
- Sunset: for shooting the red of the sunset beautifully

- Program Auto: For shooting with the exposure adjusted
automatically (both the shutter speed and the aperture value), while
allowing you to adjust other settings manually.
- Aperture Priority: This mode allows you to shoot after adjusting the aperture value manually, letting the camera set the appropriate shutter speed. This mode gives you greater control over the depth of field.
- Shutter Speed Priority: This mode allows you to shoot after adjusting the shutter speed manually, letting the camera set the appropriate aperture. With a high shutter speed, the moving subject appears as if it is frozen on the image. With a slow shutter speed, the moving subject appears as if it were flowing.
- Manual Exposure: This mode allows you to shoot after adjusting the exposure (shutter speed and aperture) manually.
- Continuous Priority AE: The camera shoots continuously while
the shutter button is pressed fully down.
- Movies: Recording movies in Full HD or standard definition in 16:9 or 4:3 aspect ratio.
Exposure Compensation: Exposure compensation is used to alter the camera's standard exposure setting. You can make the image look lighter (increased exposure) or darker (decreased exposure). The exposure compensation amount can be set up to +/-3.0 EV in 1/3-step increments.
AE Lock: You can fix the exposure before deciding on the composition when taking a picture. This is effective when the metering object and focusing object are different or when you want to shoot continuously while keep the same exposure value.
Metering Mode: A 1200-zone evaluative sensing system provides multi-pattern measuring for superior exposure control accuracy in a wide range of lighting conditions. You can select the method for measuring the brightness of a subject from the following three methods:
- Multi Segment: This method uses the whole screen divided into 1200 zones to measure light.
- Center Weighted: While emphasizing the central area of the screen, this method measure the average brightness of the entire screen.
- Spot: This method measure light only in the spot metering circle in the center of the frame.
White Balance: You can adjust the color tones according to the lighting conditions. You can choose from the following WB options, and adjust the +/- 3 to fine tune the colors:
- Auto WB: This mode adjusts the white balance automatically.
- Daylight: This mode adjusts for outdoors and sunlit subjects.
- Shade: This mode adjust for shady conditions on a clear day.
- Cloudy: This mode adjust for a cloudy sky.
- Incandescent: This mode adjusts for incandescent lighting.
- Fluorescent: This mode adjusts for florescent lighting (select Warm white, Cool white, Day white, or Daylight)
- Flash: This mode adjusts for flash conditions.
- Custom: In a scene where the ambient light consists of multiple types of light sources, use of the custom white balance is recommended in order to accurately reproduce the whiteness.
Color Temperature/Color Filter: You can adjust the white balance further by selecting Color Temperature or Color Filter in the Custom White Balance option. With Color Temperature, the higher the number, the more reddish the image, and the lower the number, the more bluish the image. Color Filter achieves the effect of Color Compensation filters for photography. Based on the set color temperature as the standard, the color can be compensated to Green (G) or Magenta (M).
Picture Effect: You can select the desired effect filter to achieve more impressive and artistic expression. There are several Picture Effect options, including Toy Camera, Pop Color, Posterization, Retro Photo, Soft High-key, Partial Color, High Contrast Mono, Soft Focus, HDR Painting, Rich-tone Mono, and Miniature.
ISO Settings: ISO is a unit of measurement of sensitivity to light. The larger the number, the higher the sensitivity. The camera's ISO can be set manually or automatically, depending upon the exposure mode:
- Auto, Sweep Panorama, or Scene Selection: When the exposure mode is set to Auto, Auto+, Sweep Panorama, or Scene Selection, the ISO is fixed to Auto.
- P/A/S: When the exposure mode is set to Program, Aperture Priority, or Shutter Priority, and ISO is set to Auto, the ISO speed is automatically set between 100 and
- Manual: When the exposure mode is changed to Manual, the ISO is automatically changed to 100, and you can set it according the shooting conditions to between 100 and 16000. Auto ISO is not an option in the Manual shooting mode.
Built-in Flash: In a dark location, using the built-in flash, or optional flash, allows you to shoot the subject brightly, and it also helps prevent blurred photos due to camera shake. The SLT-A57 features a pop-up flash, and an accessory shoe for attaching an optional external flash. The range of the built-in flash depends on the ISO sensitivity and aperture value. The
A57 offers the following flash modes:
- Autoflash: In auto mode the flash automatically fires if it is dark or against light.
- Fill-Flash: In this mode the flash fires every time the shutter is released.
- Slow Sync: Slow sync shooting allows you to shoot a clear image of both the subject and the background by slowing the shutter speed.
- Rear Sync: In rear sync mode, the objects illuminated by other light sources are captured first, then the flash is fired right before the exposure is completed.
- Wireless: The camera can use the flash light to transmit signal to an external off-camera flash to produce a more three-dimensional image. (Requires optional wireless flash unit such as
Noise Reduction: The camera offers Long Exposure and High ISO Noise Reduction (NR) to automatically reduce the grainy noise found in photos during long exposures or high ISO settings.
You can also select Multi Frame Noise Reduction when shooting multiple
Anti-Dust Technology: Changing lenses in a DSLR can allow dust to enter the camera. To help keep the image sensor cleaner for better pictures, the
A57 utilizes a static-free anti-dust coating on the imager's filter. The camera also has a cleaning function which vibrates the image sensor for a short time to knock off any dust that may have settled on the imager.
