    Lens Mount

    Sony Alpha SLT-A57 has Sony A lens mount. Due to APS-C sensor its crop factor (also called lens multiplier) is 1.5x. This means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length times 1.5.


    In-Body Image Stabilization

    The camera has a built-in Sensor Shift in-body image stabilization (IBIS). This means that you are still getting vibration reduction when camera is paired with non-image stabilizied lenses. It also works with lenses with optical image stabilization and in combination can achieve even better compensation.
