Sony will release the new α55 and α33 cameras with translucent mirror technology


    Sony will be the first in the world to use translucent mirror technology in digital cameras.
    Thanks to this innovative system, there is no need to raise the mirror during the shooting process, which in turn will allow to achieve high speed burst shooting, up to 10 frames per second (for the older model). For comparison, the top-end Canon 1D Mark IV camera demonstrates this shooting speed.

    In addition, this system will help make the camera easier and fix the problem of accurate focusing while shooting video. Now you can use fast and accurate tracking autofocus when shooting movies.

    The technology is undoubtedly promising, and can become a turning point in the development of DSLR cameras.
