Sony SLT A55

SLT A55 and SLT A33 is a new product from Sony using company’s translucent mirror design. The best thing about The Single Lens Translucent (SLT) cameras is that it’s offer live view with full-time fast phase-detection AF whether in stills or movie shooting. The way they function is by having a fixed, semi-transparent mirror that redirects a small amount of light onto the AF sensor while allowing the rest through onto the main imaging sensor.

The α (pronounced Alpha) family of interchangeable lens cameras from Sony grows with the compact, ultra-responsive new α55 and α33.

Sony’s first-ever digital cameras to employ Translucent Mirror Technology showcase an innovative optical system that opens up dramatic new shooting possibilities. In contrast with conventional DSLR cameras, Translucent Mirror Technology uses a fixed, translucent mirror that ‘splits’ the optical pathway between the main image sensor and a separate phase-detection autofocus sensor.

High-resolution live image preview with rapid, accurate phase detection autofocus is thus available at all times – either via the angle-adjustable 7.5cm (3”) LCD or precision Tru-Finder (electronic viewfinder). This also ensures that even moving objects stay in sharp focus at all times, whether you’re shooting Full HD video or stills.

Translucent Mirror Technology overcomes other traditional limitations of DSLR models, with its simplified mechanical design shrinking camera size and complexity. This makes the α55 and α33 a compelling choice for casual photographers who want to capture spontaneous family moments and travel scenes with less to carry.

Full-resolution shooting at up to 10fps with precise AF tracking
Ground-breaking Translucent Mirror Technology allows high-speed shooting with the α55 at up to 10fps (α33: 7fps) in Continuous Priority AE mode. This represents the world’s fastest burst continuous AF shooting performance of any interchangeable lens camera with an APS-C size sensor.
