Only three months after the start of the NEX and NEX-3-5-eyed Direct View (SLD) takes cameras, Sony has to offer interchangeable lenses, or in a different direction with the SLT and SLT Alpha-A55-A33. Instead mirrorless digital cameras use the new "semi-transparent mirror", better known known as a film mirror. This advanced semi-transparent mirror is fixed during the operation, while most of the light reaching the image sensor, while a small percentage is reflected on a dedicated autofocus sensor.

And "what makes this technology so exciting real-time AF phase detection during the shooting of up to ten to 16 megapixels per second with the A55, and seven of 14 megapixels per second in the A33. At 10 frames per second from a different camera, you need is for professional cameras, which cost about $ 5,000 to do, and are not yet able to auto focus in real time between shots such as the new Sony Alpha cameras SLT. Real-time phase detection autofocus is also still available in video mode, which can affect any current DSLR.

When designing half-silvered mirror is not as space efficient as the design of a room without a mirror of WW is still lower than a traditional SLR, many of which vibrate to make way mirror must provide the first imaging can begin. This means an unusual case of reflex compact standards, although there is still a little "more than one SLD, particularly in relation to body fat. Unlike SLD cameras, but cameras Sony Cyber-everyone accepts the full range of standard Alpha-mount lenses, a significant advantage if you already have an extensive collection of Alpha mount lens.

Because the semi-silvered mirror reflects only enough light to the autofocus sensor, not an optical viewfinder, as most models can allow cuticles, Sony has adopted a view in full-time direct, Alpha A55 and A33. Instead of the traditional optical viewfinder of a camera, an electronic viewfinder camera with 1,152,000 pixels SLT. The LCD viewfinder is time-division multiplexing - that is, the sequence shows all the colors of each pixel, rather than separate, the adjacent points of color electronic viewfinder more. This makes it difficult to distinguish individual pixels. The Sony Cyber-Series cameras also sport a wide-aspect 3-inch LCD with resolution of 921 600 points. Taking full advantage of full-time Live View shooting of the camera, the LCD ultra-thin tilts 180 degrees vertically and 270 degrees swivel for easy viewing from virtually any angle. The devices are also reinforced TruBlack technology borrowed from Sony.

Several features have been hot NEX Sony Cyber-shot digital cameras, including Sweep Panorama, 3D Sweep Panorama leads, Auto High-Dynamic Range and how Twilight of the laptops, each strategically combine and align multiple images in one at once, without interruption. It's something quite impressive. In addition, Sony has added an additional mode for the series cameras SLT - Multi-frame NR -, which is similar to twilight mode at hand, but allows the ISO sensitivity can be determined.

Sells the Sony Alpha A55V, the version of the United States, a striking feature of the A55 and A33 will not: with a GPS receiver. In this way, both images and movies are automatically linked to information on where they were taken.

The Sony Alpha A55 and A33 to accept Memory Stick Pro Duo / Pro Duo and SD / SDHC / SDXC media, and are powered by InfoLITHIUM batteries with electricity.
