The 0.85×-M Multi Reducer expands the FCT-65D’s field of view by reducing its focal length from 400 to 340 mm, at an F/D ratio of 5.2. Its four-element, three-group design provides a 44-mm image circle suitable for full-frame cameras. This intermediate focal length allows for a different framing than that offered by the FU reducer and the FC/FS 1.04× corrector.
The M version includes its own dedicated CA ring and is compatible with the FCT-65D as well as the FC-50 when used with the adapters provided by Takahashi. On the FCT-65D, the diagram shows the rotating collar, the reducer with its CA ring, and then a DX-60W photo ring adapted to the camera body. The M52 × 0.75 thread indicated on the camera side corresponds to the back of the supplied CA ring.
