Thanks to its semi-transparent mirror, the A55 can autofocus continuously while capturing video at up to 1920x1080, 30 fps. It also has the fastest burst speed for its price range, and extremely fast AF, for the best DSLR live view yet.
At a time when many new interchangeable-lens cameras have been forgoing reflex mirrors altogether, Sony’s new Alpha 55 (and Alpha 33) take a radically different approach. Instead of ditching the mirror—and with it, speedy, reliable autofocus—Sony gave these two DSLRs a semi-transparent mirror that doesn’t flip up and down. The result: Cameras that can autofocus continuously while recording high-definition video, and fire off stills at high burst rates—and that keep the existing Alpha lensmount for compatibility with the entire Sony lens catalog.
