Overview
The Metabones Olympus OM to Micro Four Thirds Speed Booster ULTRA 0.71 (Black Matt) allows Olympus OM lenses to be mounted on Micro Four Thirds (MFT/M43) cameras while increasing the maximum aperture by one stop and improving overall optical performance. Featuring a 5-element/4-group design with ultra-high index tantalum-based glass, it reduces the crop factor from 1.5 to 1.07, delivers sharper corners, reduced distortion, and minimized vignetting. A detachable Arca-compatible tripod foot ensures professional mounting options for stable shooting.
Optical Performance
The Metabones Olympus OM to Micro Four Thirds Speed Booster ULTRA 0.71 (Black Matt) is engineered to bring the best optical performance from full-frame Olympus OM lenses to Micro Four Thirds cameras. This adapter increases the maximum aperture by one stop, reduces the crop factor, and makes lenses effectively wider, allowing more light and a shallower depth of field for superior low-light performance and cinematic imagery.
Design and Features
The ULTRA design incorporates a revolutionary 5-element/4-group optical layout using ultra-high index tantalum-based glass, designed by Caldwell Photographic in the USA (patent granted). This advanced optical system minimizes distortion, reduces vignetting, and ensures sharp corners across the frame. Professional-grade zoom lenses such as the 24-70mm f/2.8 or 70-200mm f/2.8 can be transformed into faster, wider equivalents, while high-speed primes like the 50mm f/1.2 become 35.5mm f/0.9 lenses, maintaining excellent contrast and resolution from center to edge.
Compatibility
The precision-machined adapter features a detachable tripod foot compatible with Arca Swiss, Markins, and Photo Clam ball heads, providing stable support for both photography and video. The Speed Booster ULTRA is fully compatible with DX-sized mirrorless sensors, making it ideal for Micro Four Thirds systems.
