    NOTES:

    • Because the LA-EA3 and LA-EA4 support 35mm full-frame sensors, the light passage on these adapters is larger than the LA-EA1 and LA-EA2 which causes vignetting.
    • If you are using the NEX-3, NEX-C3, NEX-5 or the NEX-VG10, a firmware update for the lens and/or the adapter is required. Downloads are posted on your model support page.
