Metabones Canon FD Lens to Fujifilm X Speed Booster ULTRA 0.71x II Adapter

Under the hood of the Metabones Canon FD Lens to Fujifilm X Speed Booster ULTRA 0.71x II Adapter lies a cutting-edge optical design that elevates your photography experience. This advanced adapter features a sophisticated 5-element/4-group optical construction, utilizing ultra-high index tantalum-based optical glass. This innovation ensures exceptional optical performance, delivering sharper corners, minimized distortion, and reduced vignetting for your images.

The Speed Booster ULTRA maintains a magnification of 0.71x, effectively reducing the crop factor of mirrorless cameras with DX-sized sensors, such as those with Sony E-mount and Fuji X-mount, from 1.5x to a more expansive 1.07x. This allows photographers to achieve a broader field of view, closely resembling the experience of full-frame photography.

What sets the ULTRA design apart is its use of exotic materials, pushing the boundaries of glassmaking technology. This results in an adapter that is well-corrected for use with nearly all full-frame SLR lenses, regardless of exit pupil distance. The Speed Booster ULTRA excels with professional-grade f/2.8 zoom lenses, such as Canon's 24-70mm f/2.8 and Nikon's 70-200mm f/2.8, transforming them into high-speed zooms of 17-50mm f/2.0 and 50-142mm f/2.0, respectively.

Additionally, high-speed fixed focal length lenses, like a 50mm f/1.2, are converted into a remarkable 35.5mm f/0.9 lens, offering superb contrast and resolution from the center to the edges of the frame. This adapter is an essential tool for photographers seeking to enhance their lens capabilities and achieve stunning image quality with their Fujifilm X-mount cameras.
