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 including 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. Mechanical Patented positive-lock EF lens mount The tripod foot is detachable and compatible with Arca-Swiss, Markins and Photo Clam ball heads Flocking to reduce internal reflection Satin surface finish Aluminum alloy and brass construction with chromium plating Rubber gasket protects the RF mount connection from dust and moisture Electronic Autofocus speed is properly adjusted to account for and leverage the shorter focal length and the brighter maximum aperture Dual-pixel autofocus (DPAF) and video AF support It is powered by the camera body as with most lenses, no external power source required LED indicator shows communication status Build-in multi-function control wheel (turn/ push-in) for assignable functions (eg.
