  • Wireless Start/Stop of GH4 and BMPCC

The Aputure DEC LensRegain Adapter - EF/EF-S to MFT-Mount is an adapter that adds a focal reducing optical element that allows a cropped sensor camera to have a full-frame-like view. This allows you to use EF lens on Micro 4/3 mount camera bodies. The MTF performance is enchanced and gives an additional stop of light.

0.75x Magnification & Super 35mm View

The 0.75x degree of magnification is deliberately chosen to get you the equivalent of a Super 35mm camera when a Canon EF 50mm lens is attached to a MFT camera body.

Add an Additional Stop of Light, T-Stop Display

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.

Focal-Reducer & Performance Enhancer

In addition to getting a full-frame-like view, the DEC LensRegain has 7 layers of 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.

Follow-Focus & Focus-Reducer

The DEC LensRegain functions both as a follow focus and a focal-reducing-adapter. The 2.4 GHz 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.

Updated Design

The DEC LensRegain also features an all-metal build for durability and an extra 1/4" mount for easier mounting onto your existing equipment like electronic stabilizers, Steadicam, and rocker arm sideways. A separate extended cable and bracket allow for a wider range of possible set ups.
