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.  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.\u003c\/p\u003e\n\n\n\n\u003cp\u003e\u003cstrong\u003eOptical\/Mechanical\u003c\/strong\u003e\u003c\/p\u003e\n\n\n\n\u003cul\u003e\n\n\t\u003cli\u003eIncrease maximum aperture by 1 stop.\u003c\/li\u003e\n\n\t\u003cli\u003eIncrease MTF.\u003c\/li\u003e\n\n\t\u003cli\u003eMakes lens 0.71x wider.\u003c\/li\u003e\n\n\t\u003cli\u003eAdvanced 5-element\/4-group optical design incorporating ultra-high index tantalum-based optical glass by Caldwell Photographic in the USA (patent pending).\u003c\/li\u003e\n\n\t\u003cli\u003eNew positive-lock EF lens mount.
