2.0x Anamorphic Squeeze, Creates 2.66:1 Images on 4:3 Sensors, Near / Normal Focus Adjustment, Mounts to Lenses with 62mm Front Thread. The SLR Magic Anamorphot-50 2.0x Anamorphic Adapter allows you to expand your creative horizons enabling you to capture footage with a 2.66:1 aspect ratio on your camera with a 4:3 sensor. This results in an image that out of the camera will look distorted as if your subjects were stretched taller and thinner than normal. This is easily corrected in post with virtually any modern NLE creating an image suitable for viewing on wide-screen. The Anamorphot-50 features adjustable focus marked normal and near. The near adjustment allows you to focus on subjects closer than approximately 26' away; setting the adapter to normal allows you to focus on subjects from approximately 26' to infinity. It mounts to lenses with a non-rotating front and a front thread diameter of 62mm. SLR Magic recommends that the Anamorphot-50 2.0x be used with lenses that have a front element that is physically no larger than 50mm in diameter.
