Experience the Alpha SLT-A57, Sony’s newest addition to their Alpha DSLR series. As the successor to the SLT-A55, the new SLT-A57 includes advanced features such as translucent mirror technology, a 16.1 MP resolution and BIONZ processor, 12 fps continuous shooting1, Full HD movie at 60p (50p)2, and the world’s first3 Auto Portrait Framing. Standard zoom lenses become like telephoto zoom lenses thanks to Clear Image Zoom, which realizes a high-resolution look even when shooting with digital zoom making it dramatically easier to get the best shot.
12 fps tele-zoom high-speed shooting
Every second, you can capture up to 12 dynamic close-ups of subjects in motion. Tele-zoom Continuous Advance Priority AE magnifies the center of the action 1.4x to bring subjects closer at a clear 8-megapixel resolution. You can also team Smart Zoom with 2x magnification for super zoomed shots (4MP, S size). The a57 also supports 10 fps continuous shooting at the camera’s highest resolution (16.1 megapixels)4.
15-point AF system with 3 cross sensor
The renowned precision of Sony’s 15-point AF system, previously reserved for higher grade models, ensures fast and accurate TTL phasedetection autofocusing wherever and whenever you shoot. Even when capturing moving subjects in dim lighting, the three vertically aligned cross sensors deliver accurate and reliable tracking. You can choose any of four AF area modes (Wide, Zone, Spot or Local) depending on your needs.
High sensitivity (ISO 100-16000)
The large Exmor APS HD CMOS sensor provides an extremely wide sensitivity range of 7 1/3 steps. You can use AUTO ISO (100-3200) for outstanding results in most lighting conditions or manually raise sensitivity up to ISO 16000 when lighting is low. Even at high sensitivity settings, the a57 captures every detail with natural tonal gradations and extremely low noise. This makes the a57 perfect for shooting indoor athletes at high shutter speeds without a tripod or reproducing the mood of candlelit rooms without supplemental lighting.
Full-time Continuous AF
Even at maximum continuous shooting speed and during live-view movie shooting, accelerated full-time continuous phase-detection autofocusing keeps your subject in sharp focus without the slightest delay. This remarkable AF performance, made possible by Translucent Mirror Technology, lets you effortlessly capture dramatic moments and expressions in all types of situations with professional-looking results.
Quick AF Full HD Movie
Even when shooting movies at Full HD resolution5, the a57 employs speedy full-time continuous phase-detection autofocusing. Most interchangeable lens cameras revert to contrast-detection AF that slowly hunts for the correct Full manual movie shooting focus when shooting movies. But the a57 delivers the same swift, accurate focusing as during still photography to capture even fast-moving subjects with clarity. You can even lock exposure, switch the focus point, enjoy digital zooming and more while shooting movies for expanded creative control.
16.1 MP resolution with Exmor APS HD CMOS sensor and BIONZ image processor
Every detail of your scene is beautifully captured by Sony’s proprietary Exmor APS HD CMOS sensor. In addition to offering impressive 16.1-effective-megapixel resolution, the a57’s extra-large dimensions deliver supreme sensitivity in low-light conditions and gorgeous background defocusing effects beyond the capabilities of conventional camcorders. Moreover, dual noise reduction and enhanced BIONZ image processing ensure smooth gradations with minimal noise in low-light conditions. This means you can add a cinematic sense of drama to virtually any scene.
Release time lag
When you press the shutter button, the a57 responds in 0.05 second — a blazing speed that rivals professional cameras. Made possible by an innovative electronic front curtain shutter, this accelerated response lets you capture decisive moments with utmost confidence. The electronic front curtain shutter also produces less shutter noise and vibration than a mechanical front curtain shutter (which can be activated if desired through the MENU).
Enhanced Object Tracking
Newly improved Object Tracking utilizes powerful predictive focusing algorithms, 15 AF points in a wide focus area, blazing-fast BIONZ image processing and Sony’s original subject recognition technologies to track subjects with speed and precision. When your subject is a person, it automatically switches between face detection tracking and object tracking, depending on whether your subject is facing the camera.
AVCHD Ver. 2.0 (Progressive) Full HD 60p (50p)2 movies
Create movies of amazing clarity that play extra smoothly by recording them at Full HD resolution (1920 x 1080 pixels) in the AVCHD Ver. 2.0 (Progressive) format — at the extremely high frame rate of 60 (50)2 fps. You can easily download the movies to your computer for editing and recording to Blu-ray media, which is highly compatible with the AVCHD Ver. 2.0 (Progressive) codec. Sony’s lightning fast Exmor APS HD CMOS sensor and Full-time Continuous AF ensure flawless capture even at accelerated 60 (50)2 fp.
Full manual movie shooting
The a57 frees you to realize your creative moviemaking vision. P/A/S/M modes (Program, Aperture Priority, Shutter Priority and Manual) let you flexibly adjust aperture and shutter speed to modify the depth of field and achieve effects like defocused backgrounds when shooting movies in the manual focusing mode. On-screen prompts provide assistance to make full manual operation quick, easy and comfortable.
Audio noise reduction
Sound is captured clearly with minimal noise thanks to a high-performance stereo microphone on the mirror housing and advanced noise reduction that effectively suppresses AF lens drive noise via innovative NR algorithm.
24p (25p)2 cinema-like expression
Movies played at theaters are traditionally captured at 24 (25)2 fps, creating a subtle but unmistakable look that film lovers everywhere associate with the cinema. Simply by capturing your movies at the same frame rate, in the progressive format at 24p (25p)2, you can recreate this look and endow your movies with an added sense of quality and drama. This feature, together with interchangeable-lens flexibility, exceptional image quality and advanced a57 capabilities, makes it easy to achieve your moviemaking aspirations.
Like a movie director, you can use whatever lens most effectively brings out the moment. Whether fisheye, telephoto, macro, fixed focal length or zoom lens, the a57 lets you take advantage of almost any system A-mount lens. Moreover, all of these lenses are compatible with the highspeed phase-detection AF system in the a57, enabling clear results in the most challenging conditions.
One-touch movie access
With one press of the Movie button, the a57 is ready to roll. The camera immediately enters movie recording mode even if you were shooting photographs continuously or in single-frame mode. It’s the quick and easy way to capture every moviemaking opportunity.
Auto Portrait Framing
Simply photograph a person and new Auto Portrait Framing — the world’s first feature of its kind3 — will save an additional, optimally framed image in the vertical or horizontal orientation. The feature even recognizes the direction your subject is facing and captures more of the scene in that direction to create a more appealing balance. Auto Portrait Framing employs face detection technology and the “rule of thirds” principle to achieve this amazing feat. It also applies Sony’s proprietary By Pixel Super Resolution Technology to Clear Image Zoom to ensure trimmed images feature the same number of pixels as the original. Even close-ups provide great results thanks to highly dramatic trimming.
Clear Image Zoom
Dramatically enhanced Clear Image Zoom utilizes proprietary By Pixel Super Resolution Technology to zoom the center of your image up to 2x with nearly imperceptible degradation. It virtually doubles your zooming range to that of zoom lenses when using a standard lens or to that of super telephoto lenses when using a telephoto lens. So you can create dramatic “close-ups”, enjoy greater shooting flexibility and take more advantage of the brightness of compact single focus lenses.
Face Detection, Smile Shutter and Face Registration
You can always capture faces at their best with the a57. Face Detection technology ensures that facial features are clearly focused and skin tones are accurately reproduced by fine-tuning parameters such as exposure, white balance, flash and D-Range Optimizer. Smile Shutter captures smiles at just the right moment by automatically releasing the shutter when smiles reach the desired level, while Face Registration lets you register up to eight people for the camera to prioritize when detecting faces in groups.
Give your photos and movies a creative look with Creative Style settings. Depending on the scene and your creative intentions, simply select any of 6 customizable settings (Standard, Vivid, Portrait, Landscape, Sunset, or Black & White) and the camera will adjust color and other image parameters accordingly. You can also fine-tune contrast, saturation6 and sharpness to suit your personal preference and achieve just the right finishing touch.
Ordinary scenes become extraordinary photos and movies with Picture Effect. Choose from 11 customizable modes and 15 effects that significantly increase visual impact by adjusting camera parameters and applying advanced processing techniques. Settings include HDR Painting, Richtone Monochrome, Soft Focus and a Miniature mode that makes subjects look like miniature models. You can even monitor most effects in real time while shooting.
Enhanced new Tru-Finder
The Tru-finder electronic viewfinder delivers class-leading viewing ease thanks to sharp 1440k-dot (SVGA) resolution, a 23.1mm eye-point, and a notably wide 31.9-degree viewing angle that leaves competing optical viewfinders behind. A 100% field of view combines with faithful effects previews to ensure that what you see in the viewfinder is exactly what you see in your photos and movies. So you can fine-tune every aspect of your image with confidence and achieve desired results. On-screen displays keep you informed of current camera settings.
Sweep Panorama / 3D Sweep
Simply sweep the camera to capture breathtaking vistas. The 57 automatically records and seamlessly stitches a sequence of photos to create a spectacular image. 3D Sweep Panorama records separate right- and left-eye images to bring scenes alive when viewed on an HDMI-compliant 3D television8.
Capture more details in the shadows and highlights by activating Auto HDR. With one press, this instant High Dynamic Range mode takes three exposures at different settings and composites the best details from each — in the highlights, mid-tones and shadows — to create a single image with wider dynamic range than any single exposure could possibly capture. You can even shoot without using a tripod. The resulting HDR image is simply breathtaking in its detail, rich color and impact.
Dynamic Range Optimizer (DRO)
DRO uses proprietary Sony technology to bring out details in the highlights and shadows and deliver naturally bright images. It can be used during continuous shooting and provides five userselectable levels of compensation.
Superior Auto mode
Relax and enjoy the convenience of point-and-shoot operation. Superior Auto mode automatically detects and analyzes shooting conditions and adjusts camera settings accordingly to achieve optimal results. It also activates advanced functions like continuous shooting if subjects are moving fast and Auto HDR if details are getting lost in the shadows and highlights. Active settings and functions are displayed on screen for easy confirmation at a glance.
Software and cloud service
Powerful, intuitive bundled software and a cloud service help you make the most of your photos and movies. Enjoy editing, file management and more.
