Allowing you to mount a Canon FD lens on a Micro Four Thirds camera body, this Lens Turbo Adapter Mark II from Mitakon Zhongyi is a manual adapter that maintains infinity focus and image quality, and well as increases the maximum aperture and angle of view. Four elements are featured in the adapter’s design, including one extra-low dispersion element, which helps to deliver a well-corrected image with edge-to-edge sharpness and illumination. This optical design also condenses the light reaching the sensor in order to gain one effective stop of light and increase the angle of view by 0.726x to somewhat lessen the crop factor of Micro Four Thirds cameras.
In addition to the optical design, this adapter features a durable metal housing along with stainless steel mounts for secure lens-to-adapter and adapter-to-camera connections. As a manual adapter, electronic communication, including aperture control and autofocus, is not supported between the camera and lens.
