Sony Alpha SLT-A57 16.1 MP Exmor APS HD CMOS Sensor DSLR with Translucent Mirror Technology and 3D Sweep Panorama
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 shootingThe 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.
Interchangeable-lens freedomLike 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.
Creative Style 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.
Picture Effect 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.
Auto HDR 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 servicePowerful, intuitive bundled software and a cloud service help you make the most of your photos and movies. Enjoy editing, file management and more.

I tested the clear zoom feature further tonight and I think that it works as advertised which is amazing. You can digitally magnify the image up to 2.8x more while still retaining very good image quality through Sony's image enhancement feature. I included some pictures taken with my telephoto lens on the Sony a57 product page here on Amazon shot at an 8 Mp resolution. Look for yourself. I made my 200mm telephoto lens a 400mm with the push a button. There is a picture taken with my 400mm lens for comparison. It doesn't look like a gimmick to me. 4-29-12 I uploaded more pictures to the Sony SLT-a57 product page after a trip out "birding" with an 400mm lens. I think people interested in photographing wildlife should consider this camera.
Update: 5-23-12. Recently, I shot 3 stage events and I am satisfied that this camera's clear zoom feature works just as well indoors as outdoors. I was very impressed with the reach of this camera and the IQ of the images using it with a Tamron 70-200mm f 2.8 lens. I did not need to go above 1600 iso to get the shutter speeds I needed even with dancers and felt no need to do any noise removal in post proceeding. The feature set of this camera gives one so many options. Using the focus peaking feature with manual focusing more and more.
Another problem that is resolved when using the SLT-a57 when shooting stage events (formal concerts like choir or orchestra) or weddings is how quiet the shutter is. It is almost silent. In the past using a OVF camera with a moving mirror I could not get the shots I wanted for fear of causing shutter noise at a time when everyone in the audience should be quiet like when a soft song was being played or sung or when the couple is exchanging vows during the wedding. I would have to wait until a rise in volume occurred so the shutter noise would not be noticed. Often during concerts I shoot video and take still pictures (with two different cameras) at the same time. Then when I played the video back I could hear every shutter click when using the OVF camera like my a700 or a580. What a pain. Now I record video and shoot with the SLT-a57 at the same time and I do not hear the shutter in the video at all. Now I shoot whenever I want during the event. I love the freedom a quiet shutter mechanism gives me. The a77 also has a very quiet shutter as well. I am very happy with this purchase.
Update 10/27/12. I have shot with this camera for another 6 months and my satisfaction has only grown. I love the focus peaking feature for manual focusing. It is the best focus assist system for manual focusing in the world. I have shifted over to become a full manual mode shooter. I now have raised my photography to another level. Another feature have works excellent as well is sweep panorama. My sunset pictures are even better. I do agree with other people that Sony needs to improve the jpg engine of all their cameras especially with shooting in the shade. Anyway this is a class leading camera. An excellent choice for someone starting photography.
Update 11/30/13. I wanted to add a short update. I am still shooting with this camera. I cycle and hike a lot and even though I also own an RX100 I take the a57 with me most of the time. It is my outdoor activity camera and I have use the in camera HDR and panorama feature all the time with the focus peaking. That allows me to put the focus right where I want it in the scene. My preferred lens with this camera is the Sony 16-50mm f2.8 SSM. It takes sharp landscape pictures. I am also fond of a light weight and "poor man's" telephoto lens. The Tamron 200-400m f5.6. My copy is sharp at 400mm. The a57 camera and those two lenses stay in a backpack where I can just grab them and go. Sometimes I will include the Sigma 70mm macro for closeups. Also I have really enjoyed using the a57 with the Sony 15-50mmf2.8 SSM for video. This setup is silent and the camera does a very good job metering the stage productions I video. I can keep the exposure compensation and the clear zoom adjustments on the live view LCD and make silent and easy adjustments to the image. I just shot a high school play for the drama department and was very happy with the results. The AF with phase detection was very accurate and quick. I was very pleased that the camera never hunted once as it reestablished focus as I changed scenes. Canon is trying to make a big deal about their AF with video with the 70D. Now not is news of a new feature to me I have already been using AF during video for a year and a half. I think the negative press that the Sony SLT cameras have received are such non issues (like the 1/2 stop loose of light from the fixed mirror). Now this camera is an old model and can be bought at very good prices. I just have enjoyed this camera so much.
The Sony A57 is a great camera, feature rich, the body looks great, it takes great pictures, and the battery last over 500 pictures.
- LCD viewfinder, finally on the viewfinder all the relevant info is available, this camera is not a DSLR, but a "translucent mirror", which removes part of the vibration of physically rising the viewfinder mirror on each picture. on this the Sony is way more stable and less prone to vibration when taking pictures, the only "moving parts" are the sensor stabilization, and the sensor curtain.
- High ISO sensor, and multishot Noise reduction (takes several pictures and combine them to remove image noise of high ISO settings)
- 12FPS at 8MP o 8fps at 16MP. no other "pedigree" brand beats that.
- Great Lens. the 18-135 F3.5-5.6 is a great walk-around lens.
- Great on body features, like HDR, Panoramas, 3D panoramas, fullHD 1080P videos in 24fps, 30fps and 60fps.
- On body image stabilization: this means that you can use any old Minolta AF lens and get the benefits of the image stabilization found on the Alpha Body. On Canon or Nikon, if you need image stabilization, you need to buy expensive new lenses.
- Cheap and available Minolta AF (Maxxum and Dynax) lenses, flashs and accessories. I bought out from ebay 6 near mint different lenses for less than 300$, and 2 Minolta Flashes for less than 100$
- On body motor for lens AF. (Sorry Nikon I still have a grudge on you for the motorless bodies, many of my old Nikon AF lenses are now manual focus, and on Ebay to buy additional Minolta/Sony lenses).
- The body embedded flash, is good for 25-30ft pictures, good for indoor pictures.
- The camera has all the wireless flash features on the body to fully take advantage of any Minolta wireless AF D flash or new Sony flash.
- No grip (official or 3rd party) available for the camera yet
- APS-C sensor crop hits you on the fish-eye/wide angle lenses, killing a 1/3 of the view angle. this is a common problem for all cameras not full frame.
Side comments: if you buy a DSLR/SLT camera (any brand) make sure that you buy a cleaning/dust removal kit (sensor, mirror and lenses). my pick?:Giotto's Rocket-Air Blower Professional AA1903 Large (Red) + Lenspen Lens Pen Cleaning System + Lenspen Digi-Klear LCD Monitor Pen Digital Display Cleaning System + Accessory Kit for Canon, Nikon, Olympus, Pentax and Sony Digital SLR Cameras this worked wonders cleaning some dandruff off the mirror (windy day lens change)
UPDATE after 3 months of usage:
The camera performs great, after learning more of the options, the camera keeps impressing me. With a Minolta 50mm 1.7 lens, at night, with the light of only a single birthday cake candle i shot a great sequence of a friend blowing his birthday cake candle, amazing stuff, no flash, 12fps, and lights where solid and warm. camera is great. buy it now that the price dropped a few hundred dollars.
UPDATE after 8 months of usage:
This camera still amazes me, solid performance... I had the opportunity to play with 3 wireless flashes (2 Minolta HS5600D and one Sony 5600)... amazing results and the camera has the wireless built in... Chalk that one up for the A57 against "entry" same price range on Canon or Nikon.
I also added a few "expensive" lenses to my bag: a Sigma 170-500 F5.6 Super Tele-zoom. great for long range outdoors. the A57 performs awesome, the built in motor on the camera allows to use those oldie but goldie glasses.
Latest Firmware also adds on camera corrections for additional new wide angle lenses, to correct chromatic aberrations and distortions.
Don't buy the new A58 as a replacement of the A57, since is a more of a mix between the A37 + A57, not an upgrade... if you are looking for a upgrade, check the upcoming A7x when available, or wait for the A77 to lower the price.
