Sony's HVL-F20S External Flash for NEX Still Cameras is a lightweight, easy-to-use flash that has double the range of the NEX built-in flash. With Indoor/Outdoor settings and accurate, automatic TTL (Through The Lens) exposure when used with your NEX 3, 5, or 5N camera, you can get soft bounce lighting indoors and accurate fill-flash outdoors. A built-in diffuser helps light wide-angle photos, and a Tele setting extends the flash range for subjects further away.
Note: This flash features a proprietary flash connection that is compatible with NEX-3-series and NEX-5-series cameras. It also uses the camera's battery as its power source.
