<div id="keyfeatures">\r\n\t<div style="text-align: justify;">\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\t<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. 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. (Functional, but slower than lenses designed for still photography.)</li>\r\n\t\t\t\t\t\t<li style="text-align: justify;">\r\n\t\t\t\t\t\t\tSome EF-mount lenses 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. Use of an external microphone is advised. Some of the recently-introduced Canon-brand lenses are very quiet, however.</li>\r\n\t\t\t\t\t\t<li style="text-align: justify;">\r\n\t\t\t\t\t\t\tEarly Tamron VC lenses such as the AF 28-300/3.5-6.3 XR Di VC LD Aspherical [IF] Macro (model A20), AF 18-270/3.5-6.3\u{A0}Di II VC LD Aspherical [IF] MACRO (model B003),\u{A0}SP AF 17-50mm F/2.8 XR Di II VC LD Aspherical [IF]\u{A0}(model B005) may not be able to freely switch between OIS and IBIS because they may not report IS activity status.\u{A0}Later Tamron VC lenses equipped with USD or PZD focus motors are fine.</li>\r\n\t\t\t\t\t\t<li style="text-align: justify;">\r\n\t\t\t\t\t\t\tSome aftermarket battery grips may cause the aperture to change erraneously. This is a bug of the aftermarket battery grip but NOT arising from the Metabones Speed Booster. Turn off the aftermarket battery grip or use a genuine Sony battery grip.</li>\r\n\t\t\t\t\t</ul>\r\n\t\t\t\t</td>\r\n\t\t\t</tr>\r\n\t\t</tbody>\r\n\t</table>\r\n\t<div style="text-align:
