An innovative and high-quality accessory for photography enthusiasts, the T Speed Booster ULTRA 0.71x Adapter for Canon EF to EF-M Mount (EOS M) Camera is a versatile tool that enhances your camera's performance. This durable adapter, manufactured by the reputable brand Metabones, is designed to convert your Canon EF lens to an EF-M mount, making it compatible with a Canon EOS M camera.The T Speed Booster ULTRA 0.71x Adapter is equipped with an advanced 5-element/4-group optical design that incorporates ultra-high index tantalum-based optical glass. This sophisticated design ensures extraordinary optical performance, delivering improved corner sharpness, reduced distortion, and minimized vignetting. Like its predecessor, the revolutionary original Metabones Speed Booster launched in 2013, this ULTRA version also offers a magnification of 0.71x. This feature effectively reduces the crop factor of mirrorless cameras with DX-sized sensors (APS-C), such as Sony E-mount and Fuji X-mount cameras, from 1.5x to 1.07x. The ULTRA design utilizes exotic materials at the cutting edge of glassmaking technology, resulting in a product that is well-corrected for use with virtually all full-frame SLR lenses, regardless of exit pupil distance. This makes the Speed Booster ULTRA a top performer with professional-grade f/2.8 zoom lenses like the 24-70mm f/2.8 and 70-200mm f/2.8 zooms by Canon and Nikon, transforming them into 17-50mm f/2.0 and 50-142mm f/2.0 high-speed zooms, respectively. The T Speed Booster ULTRA 0.71x Adapter also works well with high-speed fixed focal length lenses such as a 50mm f/1.2, converting it into a 35.5mm f/0.9 lens with excellent contrast and resolution from the center to the edges of the image.Key features of this compact adapter include an increase in maximum aperture by 1 stop (with a maximum output aperture of f/0.9), an increase in MTF, and the ability to make the lens 0.71x wider. It also supports autofocus, image stabilization (IS) lens support, and Video Digital IS support (on supported camera bodies). The adapter is powered by the camera body, eliminating the need for an external power source with most lenses. It also features a detachable tripod foot compatible with Arca Swiss, Markins, and Photo Clam ball heads, and a rubber gasket to protect the EF-M mount connection from dust and moisture. The adapter's construction combines aluminum alloy and brass with chromium plating, and it has a satin surface finish for a sleek, professional look..
