About this download

Thank you for your continued interest in Sony products.

Sony is always concerned about customer satisfaction and therefore is offering a software upgrade program for Mount Adaptor "LA-EA1".

Improvements after firmware upgrade

  1. Support for the autofocus function when A-mount lens is attached to the camera.

    The following SAM lenses and SSM lenses are supported.

    SAM lenses
    DT18-55mm F3.5-5.6 SAM [SAL1855], 28-75mm F2.8 SAM [SAL2875], DT55-200mm F4-5.6 SAM [SAL55200-2], DT30mm F2.8 Macro SAM [SAL30M28], DT35mm F1.8 SAM [SAL35F18], DT50mm F1.8 SAM [SAL50F18], 85mm F2.8 SAM [SAL85F28]

    SSM lenses
    Vario-Sonnar T* 16-35mm F2.8 ZA SSM [SAL1635Z],
    Vario-Sonnar T* 24-70mm F2.8 ZA SSM [SAL2470Z],
    Distagon T* 24mm F2 ZA SSM [SAL24F20G],
    70-200mm F2.8 G [SAL70200G], 70-300mm F4.5-5.6 G SSM [SAL70300G], 70-400mm F4-5.6 G SSM [SAL70400G], 300mm F2.8 G [SAL300F28G]

    * With an A-mount lens attached, the autofocus speed will be slower than when an E-mount lens is attached. (It takes approximately 2 to 7 seconds (based on Sony’s measurement standard).  It may vary depending on the subjects or brightness of the shooting environments.)

    * Firmware upgrade of the Interchangeable Lens Digital Camera NEX-3NEX-5 (sold separately) is also required.
