If you're looking for a lightning-fast shooter that can pump out D-SLR-quality still images and video, and you won't miss an optical viewfinder, don't hesitate to get the $849.99 Sony Alpha55 (SLT-A55VL).
Screen
The display is mounted on an articulating arm that you can pull down 180 degrees or spin on its side 270 degrees—you can hold it above your head or below your waist and still angle the LCD so it's viewable.
Back
If you're not picky about viewfinders, you'll love the incredible, sharp main LCD, measuring three inches and comprised of 921.6K dots.
Top
The Alpha55's image sensor is still just as large as traditional D-SLRs (APS-C size), so it will pump comparable image quality out of its smaller body.
Left
The body of the Alpha55 looks like it has an optical viewfinder, but it's actually an electronic one (an EVF), which means it's actually a tiny high-resolution LCD screen (.46-inch with 1.44 million dots) rather than a true viewfinder.
Right
The Alpha55 measures 3.5 by 4.5 by 2.5 inches and weighs 1.10 pounds; with its default 18-55mm lens attached it weighs 1.57 pounds.
Size Comparison
The redesign of the Alpha55's internal mirror box makes the camera a little smaller and lighter than most DSLRs in this price range.
Angle
Sony uses Translucent Mirror Technology in the Alpha55, which gives the camera always-on access to its phase detect auto-focus sensor, so it can auto-focus between still shots faster than most traditional D-SLRs.
Sony's camera interfaces are top-notch, and the Alpha55 is no exception—it's the same UI you'll find on other Sony D-SLRs.
After measuring 50 spots through the frame, the camera had a very good center-weighted average of 1,981 lines per image height at ISO 100 (2,054 in the center, 1,967 part way to the corners and 1,729 in corner regions).
Menus are colorful and easy to read, and use fonts, icons and navigation similar to the Xross Media Bar found in Sony's PS3 and HDTVs.
The Sony Alpha55 was able to keep image noise below 1.5 percent up to ISO 6400. That's an excellent result, and means you'll be able to take sharp images in poor lighting environments without a flash.
