Camera Bodies
The Sony Alpha model system works on the principle that the next model up in the series has additional features to the one below; for example the α330 has the features of the base model α230 but with a tilt-angle LCD and Quick AF Live View, whilst the α380 has the settings and features of the α330 but increased resolution of 14.2 megapixels.
All Sony APS-C DSLRs have Live View, except for the Sony α100, α200, α700 and α900 series. Live View mode features a 1.4x or 2x Smart Teleconverter which digitally zooms in on the subject and reproduces pixels on a 1:1 basis, preventing degradation of picture quality.
The designation "SLT" stands for "Single Lens Translucent" which refers to a fixed beam splitter in the image path. Sony SLT can shoot movie files at Full HD 1080p AVCHD with continuous phase detection auto focus.
Along with the α33 and α55 cameras, Sony also announced the Sony α560 which can also shoot movie files at full HD stereo 1080p AVCHD, but with limited manual controls and no continuous AF.
Sony α33 (now α37), α55 (now α57), and α560 use the same technology Sony EXMOR APS HD CMOS sensor. The α33 and α55 are SLT based (fixed translucent mirrors) and can take movie files with continuous Auto Focus, whereas DSLRs using reflex mirrors typically cannot, at least not without limitations.

Famous quotes containing the words camera and/or bodies:
“The camera is an instrument that teaches people how to see without a camera.”
—Dorothea Lange (1895–1979)
“At this very moment,... the most frightful horrors are taking place in every corner of the world. People are being crushed, slashed, disembowelled, mangled; their dead bodies rot and their eyes decay with the rest. Screams of pain and fear go pulsing through the air at the rate of eleven hundred feet per second. After travelling for three seconds they are perfectly inaudible. These are distressing facts; but do we enjoy life any the less because of them? Most certainly we do not.”
—Aldous Huxley (1894–1963)
