<div id="keyfeatures">\r\n\t<div style="text-align: justify;">\r\n\t\t<u><strong>Speed Booster ULTRA \u{A0}for E-Mount and X-mount cameras</strong></u><br />\r\n\t\t<strong>Sharper corners, less distortion, reduced vignetting\u{A0}</strong><br />\r\n\t\tNew optical design: \u{A0}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.<br />\r\n\t\tLike the revolutionary original Metabones Speed Booster\u{A0}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.\u{A0} 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 fullframe 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.\u{A0} 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.

Lenses with hidden problems which may not be apparent on Canon DSLRs will lead to inaccurate and unreliable autofocus on Sony NEX. Typical problems of this kind that we have seen include an unsmooth/erratic autofocus mechanism (e.g. getting stuck intermittently at a certain focusing distance), a faulty/worn-out distance encoder or other faulty/worn-out internal sensors.</li>\r\n\t\t\t\t\t</ul>\r\n\t\t\t\t\t<div style="text-align: justify;">\r\n\t\t\t\t\t\t<strong>Other</strong></div>\r\n\t\t\t\t\t<ul>\r\n\t\t\t\t\t\t<li style="text-align: justify;">\r\n\t\t\t\t\t\t\tNo support for lens corrections such as peripheral shading, CA and distortion.</li>\r\n\t\t\t\t\t\t<li style="text-align: justify;">\r\n\t\t\t\t\t\t\tUse of Canon Cinema lenses such as CN-E 18-80mm T4.4 for still photography is not supported.</li>\r\n\t\t\t\t\t\t<li style="text-align: justify;">\r\n\t\t\t\t\t\t\tThe EF-mount lens may make audible noises during iris changes and autofocus, wich may be picked up by the built-in microphone of the camera during video recording.
