Metabones MB_SPNFG-M43-BM3 Overview

The Speed Booster Ultra 0.71x Adapter for Nikon G Lens to Micro Four Thirds-Mount Camera from Metabones allows a full-frame or APS-C Nikon F-mount lens to be mounted onto a Micro Four Thirds-mount camera. While doing so, the adapter's optics help to maximize the connected lens's apparent angle of view while providing a 1-stop increase for the camera over the lens's aperture range.

If a lens intended for 35mm film or similarly sized full frame as well as APS-C camera sensors is connected to a camera with a Micro Four Thirds-sized sensor, it would project an image larger than the Micro Four Thirds sensor was built to accept. Able to capture only the center portion of the projected image, the effective angle of view of the lens would be narrowed, creating an in-camera "crop factor." The Speed Booster Ultra 0.71x Adapter for Nikon G Lens to Micro Four Thirds-Mount Camera condenses the light from a lens designed for APS-C as well as 35mm film, or "full frame" camera sensors and projects it onto a Micro Four Thirds sensor. This allows a Micro Four Thirds sensor to utilize more of the light gathered by a connected lens, which effectively reduces the crop factor while making available to the sensor an additional 1 stop of light for each of the lens's f/stop settings.

This adapter is constructed from aluminum alloy for durability while minimizing weight and its mounting rings are made with brass to further prevent wear-and-tear. Inside are five lens elements in four groups that are designed to provide optical clarity as well as color fidelity, and a detachable tripod foot is included that features 1/4"-20 threads as well as compatibility with Arca-Swiss tripod heads.

The Speed Booster Ultra 0.71x Adapter for Nikon G Lens to Micro Four Thirds-Mount Camera does not support electronic communication between an attached camera and lens. To help determine the amount of light that enters a Micro Four Thirds-mount camera when using this adapter and a Nikon F-mount lens, an aperture dial is built into the Speed Booster Ultra 0.71x Adapter for Nikon G Lens to Micro Four Thirds-Mount Camera. The aperture dial is designed to provide aperture control for Nikon G-type lenses, which do not have an aperture ring. Nikon AI or many post-Nikon AI lenses can have their aperture settings widened or narrowed using their built-in aperture control rings if preferred.

  • Allows a full-frame AI or post-AI as well as an APS-C Nikon-F mount lens to be used with a Micro Four Thirds-mount camera
  • Maximizes apparent angle of view of combined camera and lens
  • Provides a 1-stop increase for the camera over the lens's aperture range
  • Five lens elements in four groups for optical clarity as well as color fidelity
  • Detachable, Arca-Swiss compatible tripod foot with 3/8" threads
  • Aluminum alloy components for weight reduction
  • Brass mounting rings prevent wear-and-tear
  • Locking mechanism for secure attachment of lens with push-button release

question

I want to mount my nikon-mount nikon 24-85 f3.5-4.5, my tamron 70-200 f2.8 vc on a gh4 using this item, i am aware there will be no autofocus or aperture control. Will the vr and vc on those lenses still work?
Asked by: Ari
As the Metabones Speed Booster Ultra 0.71x Adapter for Nikon F-Mount Lens to Micro Four Thirds-Mount Camera does not have any electronic contacts to allow information to be transferred from the lens to the camera, no, you would not have any automatic usage, such as autofocus, autoexposure, or Vibration Reduction/Vibration Compensation when using lenses with this adapter. The lens would have to be used fully manually. The adapter does provide aperture control by allowing you to adjust the apture using its own built-in aperture ring.

question

Will this perform autofocus + Auto-metering + auto-aperture switching ?Camera = OM-D-EM10Len =Sigma 17-50mm F2.8 EX DC OS HSM for Nikon DX mount.
Asked by: EngHuat T.
This adapter does not allow for electronic communication between the camera and lens. You would need to focus and adjust aperture manually. You would also likely need to use stop-down metering.
