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.
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.jpg)
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.
