Sony has officially announced the rumored full-frame A850
and mid-range A550 and A500
DSLR additions to its Alpha family. The A850 offers a few
less features than the A900 but keeps the same 24.6 megapixel sensor and knocks
the price tag down to around $2,000 for the body. The new A550 and A500 offer
14.2 and 12.3 megapixel sensors, respectively and offer tilt-able LCDs as well
as fast burst shooting speeds. Read on for additional details as we take a
closer look at what each of these new models has to offer.
Sony A550
&A500 DSLRs
TheA550 andA500 use a new generation of Sony Exmor
CMOS image sensors that offer low-noise processing for high-quality pictures.
Sony calls the A550 “the first DSLR in its class with seven frames per second
shooting speed for under $1,000.” In addition, the A550 andA500 are
Sony’s first DSLRs with a built-in High Dynamic Range (HDR) feature. This
option can process the image within two seconds to give you the best highlights
and shadows in a picture. Unlike other HDR features from other manufacturers,
Sony points out that its positional interpolation technology can overcome
slight movements in camera position so that you can use the feature without a
tripod.

Both of the new
cameras also offer two Live View functions
and a 3-inch diagonal LCD screen that tilts 90 degrees up or down. The A500’s
display is a 230,000 pixelClear Photo LCD Plus screen, while
theA550 has a 921,000 pixel Xtra Fine LCD display.In addition to
Live View, the cameras also offer Face Detection technology and Smile Shutter
technology. Like other Sony alpha cameras, the A550 andA500 offer in-body
image stabilization.
The new DSLRs are compatible with Sony’s newest32GB
Memory Stick PRO-HG Duo HX media, which is designed to give users read and
write speeds for capturing photos as well as higher transfer rates of large
capacity files to a compatible PC.
TheA550 andA500 will cost about $950 and $750
respectively for the body only. Kit options with the camera body and 18-55 kit
lens will also be available for $1,050 and $850, respectively. The cameras will
be available in October.

Targeting experienced shooters looking for sophisticated SLR performance, the new A850 uses the same 24.6 megapixel sensor and most features of the flagship A900 camera introduced last year but offers a lower price than the flagship model. Key features of this camera include a 35-mm full-frame Exmor CMOS sensor and fast image processing with dual BIONZ processing engines. The camera is also capable of shooting up to three frames per second at 24.6 megapixels.
The A850 offers body-integrated SteadyShot INSIDE image
stabilization which provides an anti-shake effect equivalent of 2.5 to 4 stops.
Another key feature is the Dynamic Range Optimizer (DRO) as well as DRO
bracketing to help you capture the best shot possible.

The A850 features a 3-inch Xtra Fine LCD screen (921K). A
backlit LCD panel sits on top of the camera and displays key settings. The
camera supports high-capacity Memory Stick PRO Duo, Memory Stick PRO-HG Duo, HX
series, and CompactFlash media.
