The new Speed Booster Ultra 0.71x is an ideal match for 6x6 Hasselblad V lenses since they can now be fully utilized as they were originally designed when mounted to the Fuji GFX. Unlike 35mm format lenses used on the Fuji GFX via glassless adapters, Hasselblad V lenses adapted to the GFX via the Speed Booster Ultra are completely free of disturbing vignetting and other corner issues.

In addition to increasing the field of view and lens speed, the new Speed Booster Ultra achieves superb performance by being carefully matched to the unique optical characteristics of the Hasselblad V lenses. 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, but the results speak for themselves.

Like all Metabones Speed Boosters, the Hasselblad-V to GFX Speed Booster Ultra is optimized to fully account for the camera’s filter stack located near the sensor surface. This is especially critical when using high-speed optics like the 110mm f/2, which becomes a high-performance 78mm f/1.4.

In addition to superb optical performance, the Hasselblad-V to GFX Speed Booster Ultra is equipped with an extremely robust cine-style positive locking mechanism to ensure that no play occurs during focusing. This is especially important when using Hasselblad V lenses for cine work because even though they provide a very smooth focus movement, they tend to require more torque than lesser lenses. The new Ultra also includes a very sturdy 360-degree rotation collar and extra length Arca Swiss style tripod mounting plate.

Why Metabones®?

Since its inception, Metabones has been designing and manufacturing lens adapters recognized among professionals and enthusiasts as leaders in design and workmanship.

Contrary to the popular trend of other factories using an aluminum ring painted black on the camera-body-side, we instead take no short-cut but use precision-machined brass with chromium plating on both the camera-body and the lens sides of our adapters, in order to ensure smooth mounting, great appearance, and durability. The lens side of the adapter features a strong leaf-spring structure, strengthening the adapter-lens connection and ensuring tightness of the lens in order to reduce wear and prevent focus errors and optical alignment issues from appearing.

Metabones uses matte-black treatment to keep internal reflection to a minimum in order to maintain the maximum optical quality possible with the lens.

All Metabones Adapters follow this tradition of uncompromising precision, robust build quality and outstanding finish. Our new Smart AdapterTM series of products add industry-leading electronic interfacing technology from Canada, with true electronic control of the lens' aperture directly from the camera body.
