About Sony SLT-A57

Even when shooting in challenging conditions, the accelerated speed, supreme sensitivity and cutting-edge functionality of the Sony Alpha SLT-A57 Digital SLR Camera ensures beautiful results. The Translucent Mirror technology simultaneously directs light to the image sensor and AF sensor on a full-time basis to realize full-time live view shooting and accelerated full-time continuous face-detection autofocusing even during HD movie shooting.

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 alpha 57 captures every detail with natural tonal gradations and extremely low noise. This makes the alpha 57 perfect for shooting indoor athletes at high shutter speeds without a tripod or reproducing the mood of candlelit rooms without supplemental lighting.

When you press the shutter button, the alpha 57 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).

Sony SLT-A57 Features

  • From corner to corner, every detail of your scene is beautifully captured by Sony's proprietary Exmor APS HD CMOS sensor
  • 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 -NTSC (50 PAL) fps
  • 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
  • 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
  • With one press of the Movie button, the alpha 57 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
  • 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. And Face Registration lets you register up to eight people for the camera to prioritize when detecting faces in groups
  • 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
  • Give your photos and movies a creative look with Creative Style settings. Depending on the scene and your creative intentions, select any of 6 customizable settings (Standard, Vivid, Portrait, Landscape, Sunset, Black/White) and the camera will adjust color and other image parameters accordingly
  • 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
  • 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 31.9deg. viewing angle that leaves competing optical viewfinders behind
  • The brightness and clarity of Sony's big Xtra Fine LCD monitor brings out every detail of your scene, setting you free to clearly shoot in challenging shooting environments
  • You can preview the depth of field, motion blur and other effects of your camera settings by pressing the Preview button. The Tru-Finder and monitor display the scene almost exactly how it will appear in your photos and movies
  • Two buttons can be customized to enhance shooting convenience. You can reassign the AEL or ISO button to activate any of 24 assignable functions, including Drive Mode and Flash Mode
  • Two finder magnification ratios are selectable, allowing you to switch from the default (max.) mode to the standard (lower ratio) mode to support an extended eye-point. At the maximum 23.1mm eye-point, the entire frame is easy to see even when wearing glasses
  • Essential shooting information can be displayed in the viewfinder and monitor at high SVGA resolution for confirmation at a glance. Simply press the DISP button to display the information you desire
  • Simply sweep the camera to capture breathtaking vistas. The alpha 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 television
  • With one press, the 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
  • By suppressing noise, the Multi Frame NR mode lets you clearly capture scenes that would normally be challenging even for seasoned professionals
  • 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 user selectable levels of compensation
  • 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
  • Simply choose one of 8 Scene Selection modes (Portrait, Sports Action, Macro, Landscape, Sunset, Night Scene, Handheld Twilight or Night Portrait) & the camera will automatically optimize aperture, shutter speed, white balance & other settings to provide the best overall image quality for the scene
  • Photos can be taken in your choice of four drive modes (single-shot, continuous, bracketed or self-timer shooting), which are selectable via user-friendly icons. You can shoot continuously at 8 or 3 fps, shoot with a 2 or 10-second delay, or bracket your choice of exposure, white balance or DRO
  • The alpha 57 compensates for the shading and aberration characteristics of the lens you mount. This includes vignetting, lateral chromatic aberration and optical distortion, which can each be activated or deactivated through the MENU as desired
  • The powerful built-in flash unit automatically pops up to illuminate dark scenes. It offers various modes, a guide number of 10 (ISO100 m), an irradiation angle that covers the angle of view of a wide 18mm lens and a maximum sync speed of 1/160 sec

Sony SLT-A57 an exerience in amazing


The biggest issue and complaint I have about the 57 is that Sony was in no way clear about computer and software system requirements. To be successful using this camera with Adobe Lightroom you will need at Lightroom 4.x or better. This also implies that if you are a Mac user, that you need a processor post Intel Core 2 Duo, as Lightroom 4 has specific processor requirements. All of this is based upon that Sony has introduced a new .arw format, that Adobe will not include as a file conversion plug-in for Lightroom 3. Don't bother with the adobe arw to dng conversion utility either, as it is full of noise when the conversion is done. It would have been nice to know what daisy chain of madness I was getting myself into with the new camera, especially with the 55 being fully compliant for Lightroom 3 and not requiring a new Imac, new Lightoom to be able to process .arw. The camera physically though is chock full of amazing, and works beautifully with all my old lenses.


I'm in love!


I owned a couple of Minolta SLRs in the 80s and 90s. In fact, we've had our old Minolta AF camera locked away in a closet since we switched to digital in the late '90s. But now that my son is playing high school basketball, our very good point and shoot just isn't cutting it anymore. I agonized for weeks between this camera, the Nikon D3100, D3200, D5000 and the Canon T4i and T3i. There are a lot of review sites and comparisons and opinions on all sides. Although I had used Minolta in the past and still had a few lenses I could use, I really didn't have a dog in the fight, and would have gone with whatever seemed like the best choice. It was a close choice between the Nikon D5000 (the cheapest option), Canon T4i, and this model. In the end, I was swayed by the passionate reviews of people WHO'VE ACTUALLY USED THIS CAMERA, the big, pixel-dense display, and my few minutes with it in my hands at a store. The fact that I could save some money in lenses by using my old Minolta AF lenses again was a nice side benefit, but wasn't the decisive factor. I would have made the switch if it's what I thought needed to happen. Now three weeks into my decision, and I have to say I couldn't be happier with my choice. Instead of the stock 18-50 mm lens, I chose the 50 mm 1.8 fixed length lens, and I'm in love. The improvement in camera technology since my last use of an SLR body is stunning and the results we've achieved are fabulous--even though we're just re-familiarizing ourselves with this type of photography. Obviously, I haven't used every digital SLR on the market. And I'm sure any of the models I considered would have been more than adequate for what we need. But to say we're happy with this camera is an understatement. We've found it very easy to use, and are gradually expanding our knowledge at each opportunity. If you knew me, you'd know I'm not normally effusive. But I love this camera and the accessories we've purchased so far.
