Rated 5 out of 5

Excellent Adapter

A great marriage of my Hasselblad v lenses to my GFX 50s. The images are rendered beautifully, the extra elements of the speed booster focusing more light and detail onto the sensor. The only downside for me is the weight. I won’t be taking this kit on any longer hikes.

Focal reducer for Hassy V System lenses opens new worlds of imagery.

This is an amazing unit. By allowing me to use my Hassy V System lenses, I’ve opened up new worlds to shoot, and is a money saver to have extra lens options for a $10K camera (GFX100)... And with using Hassy lenses, that are true medium format sized, with the focal reducer to concentrate all that light to the smaller digital sensor, you gain an east stop of light. Fast lenses on large sensor cameras are rare or $$$, do this is a big plus. The unique looks are amazing... HTH, K

For photographers and videographers seeking to bridge the gap between classic medium format excellence and modern digital capabilities, the Ultra 0.71x CINE Speed Booster Adapter is a high-quality, innovative solution. This adapter is specifically engineered to pair Hasselblad V-Mount lenses with the FUJIFILM G-Mount GFX camera system, ensuring seamless compatibility and enhanced performance.

Crafted with precision, the Speed Booster Ultra 0.71x allows for the full utilization of 6x6 Hasselblad V lenses as they were originally designed, without the vignetting and corner issues commonly associated with using 35mm format lenses on the GFX via glassless adapters. By increasing the field of view and lens speed, this adapter not only broadens your creative possibilities but also enhances low-light shooting capabilities with a wider aperture, making it a versatile tool for a variety of shooting conditions.

The adapter's optical design is meticulously matched to the distinctive characteristics of Hasselblad V lenses. Each lens's exit pupil size and location were analyzed and incorporated into the design, necessitating the use of large lens elements to prevent vignetting and maintain exceptional image quality to the edges of the frame. The results are evident in the stunning, high-resolution imagery produced.

As with all Metabones Speed Boosters, the Hasselblad-V to GFX Speed Booster Ultra is optimized to account for the camera's filter stack close to the sensor surface, which is crucial when using high-speed optics. For example, a 110mm f/2 lens is effectively transformed into a high-performance 78mm f/1.4 lens, offering both a brighter image and a shallower depth of field.

Durability and precision are at the forefront of this adapter's design. It features a robust cine-style positive locking mechanism that eliminates play during focusing, which is critical for cine work where Hasselblad V lenses are prized for their smooth focus movement but require more torque. Additionally, the adapter includes a sturdy 360-degree rotation collar and an extended Arca Swiss style tripod mounting plate for secure and flexible mounting options.

In summary, the Ultra 0.71x CINE Speed Booster Adapter is a compact, durable, and innovative accessory that unlocks new creative potentials for FUJIFILM G-Mount GFX camera users, allowing them to experience the unique characteristics and superior quality of Hasselblad V-Mount lenses in a digital format.
