Used Metabones Canon FD/FL Mount Lens to Micro Four Thirds Speed Booster ULTRA 0.71x Adapter, Matte Black

Because of its innovative design and high-quality construction, the Canon FD/FL Mount Lens to Micro Four Thirds Speed Booster ULTRA 0.71x Adapter in Matte Black offers superior optical performance. This adapter features an advanced 5-element/4-group optical design, incorporating ultra-high index tantalum-based optical glass. This innovative design ensures extraordinary optical performance, with improved corner sharpness, reduced distortion, and minimized vignetting.

Like its predecessor, the revolutionary Metabones Speed Booster launched in January 2013, this ULTRA version also boasts 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 pushes the boundaries of glassmaking technology, using exotic materials to achieve high-level correction for use with virtually all full-frame SLR lenses, regardless of exit pupil distance. As a result, the Speed Booster ULTRA performs exceptionally well with professional-grade f/2.8 zoom lenses, such as the 24-70mm f/2.8 and 70-200mm f/2.8 zooms by Canon and Nikon. These lenses are transformed into 17-50mm f/2.0 and 50-142mm f/2.0 high-speed zooms, respectively.

In addition, high-speed fixed focal length lenses, such as a 50mm f/1.2, are transformed into a 35.5mm f/0.9 lens. This adapter ensures excellent contrast and resolution from the center to the edges of the image. This compact, durable, and versatile adapter is an essential tool for photographers looking to maximize the potential of their Canon FD lenses on Micro Four Thirds cameras.
