Always Enhance and Never Degrade the Performance of the Attached Master Lens. Like the ULTRA series for Sony E-mount, the new Speed Booster ULTRA m43 uses an advanced 5-element 4-group optical design incorporating ultra-high index tantalum-based optical glass. However, the new design is specifically optimised for the Micro Four Thirds sensor and filter stack, and as a result, achieves an astonishing level of performance that sets a new standard for focal reducers.

A super wide-angle prime designed for Nikon-mount DSLRs, the SP 14mm f/2.4 from Rokinon pairs an advanced optical design with simple, intuitive handling. Incorporating 18 elements in 14 groups, this lens utilises a series of aspherical, low dispersion, and high refractive index elements to reduce color fringing, aberrations, and distortions for sharp, clear, and color accurate imagery. An Ultra Multi-Coating is also featured, as well as a built-in lens hood, to suppress lens flare and ghosting for improved contrast when working in bright, direct lighting conditions. Complementing the imaging assets, a manual focus design is employed that permits working with subjects as close as 11" away, and the Aluminum-alloy housing is both lightweight and durable to support working in a variety of conditions.

New optical design: advanced 5-element/4-group optical design incorporating ultra-high index tantalum-based optical glass to achieve extraordinary optical performance with improved corner sharpness, distortion and reduced vignetting. Like the revolutionary original Metabones Speed Booster announced in January 2013, the Speed Booster ULTRA has a magnification of 0.71x, and so it 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. However, the new ULTRA design makes very effective use of exotic materials at the furthest limit of glassmaking technology, and as a result is well corrected for use with virtually all full-frame SLR lenses regardless of exit pupil distance. Thus, the Speed Booster ULTRA performs extremely 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 to produce 17-50mm f/2.0 and 50-142mm f/2.0 high-speed zooms, respectively. Similarly, high-speed fixed focal length lenses such as a 50mm f/1.2 will be transformed into a 35.5mm f/0.9 lens with excellent contrast and resolution from the Center all the way to the edges of the image.
