Sony has introduced the Alpha DSLR-A850, a full-frame 24.6-megapixel-resolution camera with an Exmor CMOS sensor, a three-inch Xtra Fine LCD screen, a pentaprism viewfinder and a nine-point autofocus system.

The new CMOS sensor captures more vibrant, lifelike colors and textures while producing images that pass through the noise reduction filter. With these two systems in place, images can still be captured in high-resolution format up to ISO 6400.

The 3-inch Xtra Fine LCD screen offers high-resolution image review, while the optical glass pentaprism viewfinder provides minimal distortion and 98 percent field coverage when setting up shots.

When focusing with the nine-point autofocus system, users are aided with focus assist points to help detect the subject and improve out-of-focus detection.

Additional features include the intelligent preview function, which previews image settings before taking a shot; "quick navi" mode to adjust settings with one hand; and the SteadyShot in-body optical stabilization system.

In addition to the existing full-frame lenses available, Sony has created the new 28-75mm f/2.8 SAM general-purpose lens.

The Alpha DSLR-A850 full-frame digital SLR camera retails for $1,999. The 28-75mm lens will be available in November for $800.
