Used Metabones Canon EF Lens to Fuji X-Mount T Speed Booster ULTRA 0.71x Adapter

How does the Canon EF Lens to Fuji X-Mount T Speed Booster ULTRA 0.71x Adapter revolutionize your photography experience This innovative adapter magnifies at 0.71x, effectively reducing the crop factor of mirrorless cameras with DX-sized sensors (APS-C), such as Sony E-mount and Fuji X-mount cameras, from 1.5x to 1.07x.

The ULTRA design employs cutting-edge materials at the pinnacle of glassmaking technology. As a result, it is well-corrected for use with virtually all full-frame SLR lenses, regardless of exit pupil distance. This makes the Speed Booster ULTRA a high-performing accessory with professional-grade f/2.8 zoom lenses like the 24-70mm f/2.8 and 70-200mm f/2.8 zooms by Canon and Nikon. It transforms these lenses into 17-50mm f/2.0 and 50-142mm f/2.0 high-speed zooms, respectively.

Moreover, high-speed fixed focal length lenses such as a 50mm f/1.2 are transformed into a 35.5mm f/0.9 lens, delivering excellent contrast and resolution from the center to the edges of the image.

Unlike other manufacturers who use an aluminum ring painted black on the camera-body-side, this adapter uses precision-machined brass with chromium plating on both the camera-body and the lens sides. This ensures smooth mounting, an attractive appearance, and durability.

The lens side of the adapter features a robust leaf-spring structure, enhancing the adapter-lens connection and ensuring the lens's tightness to reduce wear and prevent focus errors and optical alignment issues.

Metabones employs a matte-black treatment to minimize internal reflection, maintaining the maximum optical quality possible with the lens. All Metabones Adapters uphold this tradition of uncompromising precision, robust build quality, and superior finish.

The new Smart Adapter series introduces industry-leading electronic interfacing technology from Canada, offering true electronic control of the lens' aperture directly from the camera body. Both camera-side and lens-side of the adapter are made of brass, precision-machined and plated with chromium.

The adapter is designed to reach infinity focus while maintaining the correct registration distance required to maintain the optical quality of CRC lenses or lenses with floating elements. It allows the camera to automatically choose the aperture in P or S exposure modes, or you can manually adjust on the camera body in A or M modes.

The adapter also supports EXIF data such as lens identification, focal length, and aperture, making it an essential tool for professional photographers and photography enthusiasts alike.
