Metabones T Speedbooster ULTRA 0.71x II Canon EF-Sony E
Sharper corners, less distortion, reduced vignetting
New optical design: advanced 5-element/4-group optical design incorporating ultra-high index tantalum-based optical glass to achieve extraordinary optical performance with improved corner sharpness, distortion and reduced vignetting.
Like the revolutionary original Metabones Speed Booster announced in January 2013, the Speed Booster ULTRA has a magnification of 0.71x, and so it effectively reduces 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. 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 full-frame 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.
Features
• Allows users to adapt a full-frame Canon EF-Mount lens to an APS-C/Super35 Sony E-Mount camera, or a full-frame camera in APS-C mode.
• Advanced 5-element in 4-group optical construction uses ultra-high index tantalum-based glass, increasing the angle of view of a full-frame lens by 0.71x, and the maximum aperture by one stop. This effectively compensates for the 1.5x crop factor of APS-C cameras and provides an image like that of a full-frame lens on a full-frame camera.
• Electronic contacts permit transmission of data between the lens and camera enabling autofocus, auto exposure, image stabilization, aperture control from the camera body, saving EXIF information, and more.
• Status notification LED light on the adapter will show the user what mode the adapter is currently in.
• Dedicated switch for controlling in-body image stabilization.
• Programmable function button for rapid access to commonly used settings and features.
• Support for phase-detect AF with the a7R II, a7 II, a6500, and a6300 cameras.
• Compatible with Sony PXW-FS7M2 (Mark II) camera.
• Smooth iris support with select Canon (2009 and later), Tamron (SP series 2013 and later), and Sigma (2016 and later) lenses.
• Enables electronic manual focusing on lenses, such as the Canon EF 85mm f/1.2L II, that use a focus-by-wire system.
• Support for distance and zoom display, auto magnify, and auto APS-C Size Capture settings on select cameras.
• Internal felt flocking prevents reflections.
• Removable Arca-type compatible tripod foot with 1/4"-20 thread.
• Powered by camera body.
