Meike 25mm T2.2 Manual Focus Prime Mini Cinema Lens for MFT

This Lens Mount Adapter from Viltrox allows a Nikon F-Mount, D or G-Type lens to be mounted onto a Micro Four Thirds camera. While doing so, the adapter’s optics help to maximize the connected lens’s apparent angle of view while providing a one-stop increase for the camera over the lens’s aperture range.

If a lens intended for larger camera sensors is connected to a Micro Four Thirds camera, it would project an image larger than the camera’s 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.” This adapter condenses the light from an attached lens and projects it onto a Micro Four Thirds camera’s sensor. This allows the camera 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 one stop of light for each of the lens’s f/stop settings.

This adapter supports manual focusing and eight stops of aperture control. It is constructed with five lens elements in four groups that are designed to provide optical clarity as well as color fidelity, and the underside of its removeable tripod foot is tapped with a 1/4″-20 accessory thread, enabling direct attachment to a tripod or quick release plate that feature 1/4″-20 mounts.
