    SKU: C645-GFX AF 0.8x

    KIPON Baveyes introduced the focal reducer 0.8x that brings the medium format lens Mamiya 645 to Fujifilm GFX camera, virtually eliminating any crop factor image loss and maintaining diagonal angle of view.

    One stop brighter

    By reducing the focal length of the lens, C645-GFX AF 0.8x increases light transmission, effectively increasing the aperture. For example, an F2.8 lens turns to F2.0. The depth of field is more blurred.


    0.8x wider

    C645-GFX AF 0.8x reduces the focal length by 0.8, the effective focal length becomes shorter so that the shooting range is larger. It allows the medium format lens view angle to be restored on a 44x33 camera sensor, with 0.8x adapters, you can get the similar feeling like using these lenses on original cameras.


    Improve lens MTF
    The 0.8x optics feature a telecentric design, to let light come into the digital sensor as vertically as possible. For some lenses, the quality of them would be improved after using the focal reducer 0.8x. We tested Mamiya 645 55-110mm f4.5 and 80mm f1.9 lenses by Zeiss K6, after mounting the focal reducer 0.8x, the lens quality improved.


    Fast AF and strong electronic functions

    C645-GFX AF 0.8x features fast and accurate autofocus for a steady performance. Built-in electronic contacts and circuit board with chip, which support Eye-AF, lens and camera stabilization, EXIF information transmisssion, etc. The adapter is equipped with a Type-C port for firmware update. With C645-GFX AF 0.8x, you can control the aperture with the camera body.
