Good news for users of Fujifilm GFX cameras: the Metabones Hasselblad V Lens to Fuji GFX Cine Speed Booster Ultra 0.71x enables you to use classic Hasselblad glass with an increased field of view and maximum aperture. 

Bad news for users of Fujifilm GFX cameras: it comes with the necessary acknowledgement that Fujifilm's medium format cameras are in fact cropped medium format cameras. 

Traditional, 'full-frame medium format' film is 6 x 6cm – significantly larger than the 4.38 x 3.29cm dimensions of the sensor inside the Fujifilm GFX 100 (opens in new tab), Fujifilm GFX 50R (opens in new tab) and Fujifilm GFX 50S (opens in new tab) (along with the Hasselblad X1D II 50C (opens in new tab), for that matter).

However, the new Metabones Speed Booster makes it possible to use 6 x 6 Hasselblad V-mount optics while receiving a significant improvement (the titular "speed boost") in maximum aperture.

The Booster introduces a 0.71x crop factor, which effectively increases both the focal length and the speed of an adapted lens. So the legendary Hasselblad 110mm f/2 Planar FE, for example, becomes a formidable 78mm f/1.4 equivalent. 

Boasting an advanced, six-element design, the Metabones Speed Booster has been engineered to match the optical characteristics of Hasselblad lenses. According to Metabones:

"All of the Hasselblad V lenses were analyzed for exit pupil size and location, and this was fully taken into account in the new Speed Booster Ultra for the Fuji GFX. This approach dictated the use of extremely large lens elements throughout in order to avoid vignetting and maintain high quality imagery into the corners".

While Fujifilm GFX bodies do not support traditional medium format leaf shutters, such lenses are fully usable via the GFX focal plane shutter. In addition, the Speed Booster features true electronic integration of the aperture diaphragm and records full EXIF data.

The Metabones Hasselblad V Lens to Fuji G mount Cine Speed Booster Ultra 0.71x is available (opens in new tab) for $899 (£741). A non-speed boosting version, the Metabones Hasselblad V Lens to Fuji G mount T Cine Adapter, is also available (opens in new tab) for $399 (£329).
