Aputure Follow Focus DEC Lens Regain for MFT, Black (DECLR-MFT)

The Aputure DEC LensRegain for MFT adds a focal reducing optical element. That makes it not only a follow focus and adapter, but also a device that gives cropped sensor cameras a full-frame-like view. Specifically, the DEC LensRegain for MFT allows you to use EF lens on Micro 4/3 or APS-C E-mount camera bodies. It enhances MTF performance and also adds an additional stop of light. 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. In addition to getting a full-frame-like view, the 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. We're proud show that the DEC LensRegain is competitive as not only a follow focus, but also a focal-reducing-adapter built in one. The 2.4G wireless frequency allows you to wirelessly follow focus, remotely start/stop recording, and adjust aperture. The internal focal-reducing element allows you to regain the equivalent field of view of a full-frame camera. With a camera package so light, you'll be free to create what nobody has been able to achieve before.
