Filmmakers are now able to mitigate most of the 4k video crop factor of EOS-R (1.75x) and EOS-RP (1.63x), and reduce it to 1.24x and 1.15x respectively to support the newly EOS C70 (Super 35mm sensor). The field of view is now much closer to still photo mode. The Speed Booster is not intended for still photography but will work if the camera is configured to APS-C mode. It uses an advanced 5-element\/4-group optical design by Caldwell Photographic, incorporating ultra-high index, tantalum-based optical glass to achieve extraordinary optical performance with improved corner sharpness, distortion, and reduced vignetting. The Speed Booster Ultra has a magnification of 0.71x, effectively reducing the crop factor of 4k video on EOS-R and EOS-RP from 1.75x to 1.24x. It has a design that 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. 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 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\u003ch2 class=\"h2Lit\"\u003eKey Features of the Metabones Canon EF Lens to RF-mount T CINE Speed Booster ULTRA 0.71x - With Tripod Foot\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMakes Lens 0.71x Wider\u003c\/li\u003e\n\u003cli\u003eAluminum Alloy and Brass Construction\u003c\/li\u003e\n\u003cli\u003eSatin Surface Finish\u003c\/li\u003e\n\u003cli\u003ePositive-Lock EF Lens Mount\u003c\/li\u003e\n\u003cli\u003eLED Indicator\u003c\/li\u003e\n\u003cli\u003eImage Stabilization Lens Support\u003c\/li\u003e\n\u003cli\u003eAutofocus Speed is Properly Adjusted\u003c\/li\u003e\n\u003cli\u003eIncrease Maximum Aperture by 1 Stop\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv class=\"gText\"\u003e \u003c\/div\u003e\n\u003cdiv class=\"gText\"\u003e\n\u003cdiv\u003e\n\u003ch2 class=\"h2Lit\"\u003e\u003cspan class=\"h2Lit\"\u003eMechanical \u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eThe tripod foot is detachable and compatible with Arca-Swiss, Markins and Photo Clam ball heads\u003c\/li\u003e\n\u003cli\u003eFlocking to reduce internal reflection\u003c\/li\u003e\n\u003cli\u003eSatin surface finish\u003c\/li\u003e\n\u003cli\u003eAluminum alloy and brass construction with chromium plating\u003c\/li\u003e\n\u003cli\u003eRubber gasket protects the RF mount connection from dust and moisture\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003ch2 class=\"h2Lit\"\u003e\u003cspan class=\"h2Lit\"\u003eElectronic\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAutofocus speed is properly adjusted to account for and leverage the shorter focal length and the brighter maximum aperture\u003c\/li\u003e\n\u003cli\u003eDual-pixel autofocus (DPAF) and video AF support\u003c\/li\u003e\n\u003cli\u003eIt is powered by the camera body as with most lenses, no external power source required\u003c\/li\u003e\n\u003cli\u003eLED indicator shows communication status\u003c\/li\u003e\n\u003cli\u003eBuild-in multi-function control wheel (turn\/ push-in) for assignable functions (eg.
