Metabones Canon EF to Sony E-Mount T Speed Booster ULTRA II 0.71x Adapter

Overcome the limitations of your camera system with the high-quality Canon EF to Sony E-Mount T Speed Booster ULTRA II 0.71x Adapter. This innovative and durable adapter is designed to convert Canon EF lenses to a Sony E-Mount system, providing a versatile solution for photographers who use multiple camera brands. The compact adapter incorporates an advanced 5-element/4-group optical design, featuring ultra-high index tantalum-based optical glass. This cutting-edge design ensures extraordinary optical performance, enhancing corner sharpness, reducing distortion, and minimizing vignetting. The Speed Booster ULTRA II has a magnification of 0.71x, effectively reducing 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. This makes it an indispensable tool for photographers seeking to improve image quality, especially in low light conditions. The ULTRA II design utilizes exotic materials at the forefront of glassmaking technology, ensuring optimal performance with virtually all full-frame SLR lenses. It excels with professional-grade f/2.8 zoom lenses, transforming them into high-speed zooms with excellent contrast and resolution from the center to the edges of the image. The adapter also supports AF-C tracking during high-speed drive at up to 10fps on Sony A9, and offers smooth iris support with the latest Canon, Tamron, and Sigma lenses. A custom function button allows for more than 50 functions, such as Aperture Preview and Eye-AF, on A9, A7 series, A6500, and A6300. The Canon EF to Sony E-Mount T Speed Booster ULTRA II 0.71x Adapter is also equipped with a rubber gasket to protect the E-mount connection from dust and moisture, and a detachable tripod foot compatible with Arca Swiss, Markins, and Photo Clam ball heads. This adapter increases the maximum aperture by 1 stop and makes the lens 0.71x wider, enhancing your camera's capabilities. It also supports 5-axis in-body image stabilization of A7II, A7RII, and A7SII, and is powered by the camera body, eliminating the need for an external power source. With its fast contrast-detection AF on all E-mount cameras and pure phase-detection autofocus support on A9, A7RII, A7II, A6500, and A6300, this adapter ensures sharp, clear images every time. Please note that full-frame lenses are required for use with this adapter, and EF-S/DX/DC/Di II lenses are not supported. Autofocus may not work if the maximum aperture of the lens plus any EF Extender or other teleconverter attached is smaller than f/8 before boost or smaller than f/5.6 after boost. Experience the difference in your photography with the Canon EF to Sony E-Mount T Speed Booster ULTRA II 0.71x Adapter.
