This 2X Converter Lens for Sony Alpha mount and Minolta Maxxum mount lens will Double The Focal Length Of The Primary Lens Being Used. If You Attach It With Standard 50mm, You Will Have A 100mm Lens. If You Attach It With An 70-300mm, You Will Have A 140-600mm Lens. The Converter Will Work Completely With The Auto-Focus Mechanism Of The Camera As Long As The Maximum Aperture On The Primary Lens Is F4 Or Wider.
