Unlock the full potential of your Canon FD lenses with the Speed Booster Canon FD to Sony E-mount Speed Booster ULTRA 0.71x Adapter (Black) for Sony E-Mount cameras. This sleek black adapter not only reduces the crop factor from 1.5x to 1.07x, allowing for a wider field of view, but also enhances your shooting experience by maintaining exceptional optical performance. 

The Metabones Speed Booster ULTRA is a groundbreaking accessory that maintains the innovative spirit of the original Speed Booster. With a magnification of 0.71x, it effectively reduces the crop factor of mirrorless cameras with DX-sized sensors—from 1.5x to just 1.07x. This enhancement is particularly beneficial for Sony E-mount and Fuji X-mount users, enabling a more versatile shooting experience.

The ULTRA’s advanced design utilizes cutting-edge materials and glassmaking technology, ensuring exceptional optical performance with nearly any full-frame SLR lens, regardless of exit pupil distance. This results in outstanding compatibility, especially with professional-grade f/2.8 zoom lenses like the Canon and Nikon 24-70mm f/2.8 and 70-200mm f/2.8, transforming them into fast 17-50mm f/2.0 and 50-142mm f/2.0 zooms.

Additionally, high-speed prime lenses, such as a 50mm f/1.2, are transformed into a remarkable 35.5mm f/0.9, delivering excellent contrast and sharpness across the entire image frame. Whether you’re shooting portraits, landscapes, or events, the Speed Booster ULTRA ensures your creativity shines through with unparalleled image quality.
