Metabones Speed Booster ULTRA FUJI X a SONY Mount A

The Metabones Ultra 0.71x Speed Booster Adapter for SONY A-Mount Fujifilm X-Mount camera lens allows a full frame SONY A-mount lens to mount on a Fujifilm X-mount camera In doing so, the adapter optics help maximize the lenses connected apparent angle of view while providing a 1-point magnification for the camera over the aperture range of the lens
If a lens intended for 35mm film or similar sized full-frame camera sensors is attached to a camera with a sensor of FUJI X-mount APS-C size, it would project a larger image than the sensor FUJI X-mount APS-C would be built to accept Able to capture only the central portion of the projected image, the effective angle of view of the lens was reduced, creating an in-camera "crop factor." The Ultra 0.71x Speed Booster adapter for SONY A-Mount Fujifilm X-Mount camera lens condenses the light from a lens designed for 35mm film or "full frame" camera sensors and projects it onto a FUJI X-mount APS-C sensor This allows a sensor from FUJI X-mount APS-C to use more of the light collected by an attached lens, effectively reducing the crop factor while making available to the sensor an additional 1 stop of light for each of the f/stop settings of the lens
This adapter is constructed from an aluminum alloy for durability and minimizing weight and its mounting rings are made of brass to prevent further 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 3/8" threads as well as compatibility with Arca-Swiss tripod heads
The Ultra 0.71x Speed Booster adapter for SONY A-Monte Fujifilm X-Monte camera lens does not support electronic communication between a camera and the attached lens To help determine the amount of light entering a Fujifilm X-mount camera when using this adapter and a lens SONY with mount, an aperture line is built into the 0.71x Ultra Speed Booster Adapter for SONY A-Mount Fujifilm X-mount camera lens Camera bracket Allows a full-frame lens SONY with mount to be used with a Fujifilm X-mount camera Maximizes the apparent angle of view of the camera and the combined lens provides a 1-point magnification for the camera through the aperture range Five lens elements of the lens in four groups for greater optical clarity as well as detachable color fidelity, Arca-Swiss tripod stand compatible with 3/8" aluminum alloy components for weight reduction Brass mounting rings prevent wear and tear Locking mechanism for secure lens attachment with push-button release
