Just today i received my long awaited speedbooster by Zhong Yi Optics from China. I was greatly surprised of its quality and am now trying my Tamron SP Adaptall-2 lenses I have, and can also use my Nikon Fisheye on mu GX1 camera’s.

The new Nikon G – M43 version will have an integrated aperture control ring.

The Micro Four Thirds Camera Lens Turbo Adapter from Mitakon allows lenses to be mounted to Micro Four Thirds format cameras, increasing the angle of view by 0.726x and the maximum aperture of the lens by 1 f-stop.

The four optical elements of the Lens Turbo adapter condense light from the full frame lens and project it onto the camera’s sensor allowing the sensor to capture all of the transmitted light, negating the crop factor and effectively producing full-frame coverage on non-full-frame sensors. A corresponding increase in the maximum aperture of 1 f-stop makes the lens more effective in low-light situations.

This adapter features 4 optical elements including one extra-low dispersion (ED) element which reduces aberrations for better delineated images. The adapter offers a sturdy metal construction and stainless steel mounts, it attaches to both camera and lens with little play and includes a front and rear protective cap. The Lens Turbo is a manual adapter offering no electronic communication between lens and camera.

The New Nikon version features a silver aperture ring which is able to control the aperture of Nikon G lenses through the adapter.

  • Allows lens to be mounted to Micro Four Thirds camera

This lens turbo adaptor may not fit all lenses due to different extensions at the lens rear mount. Lenses with extension more than 3mm are not recommended to use this lens turbo adaptor.
