Metabones has announced its new Hasselblad V to Fuji G mount (GFX) x0.71 Speed Booster, the latest in its extensive Speed Booster Ultra 0.71x lineup.

The new Speed Booster, which provides nearly the full angle of view of the original Hasselblad V lens when used on a Fujifilm GFX camera, relies on a six-element design capable of ‘[achieving] excellent optical performance at apertures up to F1.4 when paired with the Hasselblad 110mm F2 lens.’ Metabones says it was able to achieve this performance by analyzing the exit pupil size and location of all Hasselblad V lenses and using the resulting data to develop its new Speed Booster Ultra.

As with Metabones’ other Speed Booster adapters, the Hasselblad V to GFX Speed Booster Ultra accounts for the camera’s filter stack atop the sensor, a key element, especially when using faster lenses with larger apertures.

The adapter features ‘an extremely robust cine-style’ positive locking mechanism to prevent lens movement when focusing as well as a 360-degree rotation collar and Arca Swiss style tripod mounting plate.

The 0.71x Speed Booster Ultra for adapting Hasselblad V lenses to Fuji GFX camera systems will be available starting August 16th, 2019 from Metabones’ website and authorized retailers for $899. The non-Speed Booster version will ship at the same time for $399.
