Metabones Canon FD / FL to Micro FourThirdsSpeed Booster ULTRA 0.71x (Black Matt)

The Metabones Canon FD/FL to Micro Four Thirds Speed Booster ULTRA 0.71x adapts Canon FD and FL lenses to MFT cameras, increasing maximum aperture by one stop, widening the field of view, and improving image sharpness, distortion, and vignetting thanks to its advanced 5-element optical design.

The Metabones Canon FD/FL to Micro Four Thirds Speed Booster ULTRA 0.71x is a high-performance lens adapter designed for photographers and filmmakers who want to pair classic Canon FD and FL mount lenses with Micro Four Thirds cameras from Panasonic, Olympus, and Blackmagic Design. Built with an advanced 5-element, 4-group optical design featuring ultra-high index tantalum-based glass from Caldwell Photographic, the Speed Booster ULTRA delivers exceptional optical performance with sharper corners, reduced distortion, and minimal vignetting. By reducing the focal length by 0.71x, it effectively widens your lens’s field of view and reduces the crop factor, while also increasing the maximum aperture by one stop—turning fast primes into ultra-bright optics and f/2.8 zooms into f/2.0 powerhouses. Constructed from aluminum alloy and brass with a satin black matte finish and chromium-plated mounts, the adapter is both durable and professional in appearance. It also features a detachable Arca-type tripod foot compatible with popular ball head systems for added stability during shooting. Whether you’re looking to revive vintage glass or maximize the performance of pro-grade lenses, the Speed Booster ULTRA offers unmatched optical quality and versatility.
