About Metabones Canon FD/FL Lens to RF Mount Speed Booster Ultra 0.71x Adapter, Black

When you're seeking a high-quality, durable, and innovative solution to enhance your photography, consider the Canon FD/FL Lens to RF Mount Speed Booster Ultra 0.71x Adapter in sleek black. This compact and versatile adapter is designed to convert your Canon FD lens to a Canon EF mount, enabling you to use it on a Canon EF camera body.

The adapter boasts a cutting-edge 5-element/4-group optical design, incorporating ultra-high index tanatalum-based optical glass. This advanced design ensures extraordinary optical performance, delivering improved corner sharpness, reduced distortion, and minimized vignetting.

Like its predecessor, the revolutionary original Metabones Speed Booster announced in 2013, this Speed Booster ULTRA maintains a magnification of 0.71x. This effectively reduces the crop factor of mirrorless cameras with DX-sized sensors, such as Sony E-mount and Fuji X-mount cameras, from 1.5x to 1.07x.

The ULTRA design utilizes exotic materials at the forefront of glassmaking technology, resulting in a product that is well corrected for use with virtually all full-frame SLR lenses, regardless of exit pupil distance. This makes the Speed Booster ULTRA a perfect match for professional-grade f/2.8 zoom lenses, transforming them into high-speed zooms with enhanced contrast and resolution from the center to the edges of the image.

The adapter is precision-machined from brass and plated with chromium on both the camera-body and lens sides, ensuring smooth mounting, an attractive appearance, and long-lasting durability. The lens side features a robust leaf-spring structure, strengthening the adapter-lens connection and reducing wear. This also prevents focus errors and optical alignment issues.

The adapter also boasts true electronic integration of the aperture diaphragm, allowing the camera to automatically choose the aperture in P or S exposure modes, or enabling you to manually adjust it on the camera body in A or M modes.

With the Canon FD/FL Lens to RF Mount Speed Booster Ultra 0.71x Adapter, you can expect uncompromising precision, robust build quality, and an outstanding finish, all designed to enhance your photography experience.
