The SLR Magic Anamorphot-40 1.33x Anamorphic Adapter allows you to expand your creative horizons, enabling you to capture footage with a 2.35:1 aspect ratio on your camera with a 16:9 sensor. This results with an image that out of the camera will look distorted, as if your subjects were stretched tall and thin. This is easily corrected with virtually any modern NLE, creating an image suitable for widescreen viewing.
The Anamorphot-40 features adjustable focus marked normal and near. The near adjustment allows you to focus on subjects as close as 4' away; setting the adapter to normal enables you to focus on subjects from 4' to infinity. It mounts to lenses with a non-rotating front and a front thread diameter of 52mm; it incorporates an 82mm front filter thread. SLR Magic recommends that the Anamorphot-40 1.33x be used with lenses that have a front element that is physically no larger than 40mm in diameter.
Please note that SLR Magic cautions that for full frame work a 75mm taking lens is required, a 50mm taking lens may only cover when your camera is in APS-C or S35/APS-C sensor mode. When using this adapter on a 25mm , the image will cover a Four Thirds sensor.
