0.75x Magnification, Super 35mm View. When a Canon EF 50mm lens is attached to a MFT camera body, with the simple attachment of the DEC LenRegain, your MFT camera will produce images like those from industry-standard Super 35mm cameras.
In terms of exposure, the DEC LensRegain also adds to your maximum aperture by one stop of light. That means your f/1.4 lens will work like that of an f/1.0 lens. With this advantage, a lower ISO can be set in low light shooting, and a higher shutter speed can be set while still maintaining the proper exposure. To more accurately determine exposure in relation to this additional stop, the new T-stop is also displayed on the DEC LensRegain's OLED screen.
DEC LensRegain has seven layers anti-reflective coatings on each of its 4-element, 4-group optical elements. It reduces the view of an EF lens to 0.75x and also brings more information and light to each bit of your camera's sensor. Due to the meticulously crafted quality of this extra optical element, the DEC LensRegain boasts exceptional performance when being judged in relation to MTF, anti-distortion, and anti-dispersion.
It also features a new all metal build and an extra 1/4" mount to both protect it from breaking and for easier mounting onto your existing equipment, like electronic stabilizers, and steadicam, rocker arm sideways. There is also a separate extended cable and bracket, to allow for a wider range of possible set ups.
