The Metabones EF to E Mount T Speed Booster ULTRA II improves on its predecessors by incorporating a new optical design with extraordinary sharpness with reduced distortion and vignetting. This electronic adapter allows you to pair Canon EF mount lenses with Sony E mount cameras and increases the effective field of view and the maximum aperture of the lens you're using. This combats the crop factor of your APS-C camera (or APS-C mode) while allowing you to use your favorite Canon EF mount lenses. This recent ULTRA redesign is made specifically to perform better with the professional-grade glass found in Canon's L series full frame f/2.8 zoom lenses.
This Speed Booster works by shrinking the image circle of your Canon EF lens down to better fit APS-C 1.5x crop sensors. This has the effect of making the field of view of the lens wider or, in other terms, reducing the crop factor of the camera from 1.5x to 1.07x nearly full frame. Additionally, by concentrating the image circle from a lens, this Speed Booster also "brightens" the image maximum lens apertures are increased by approximately 1 stop down to the sub-f/1.0 range. Lenses like the Canon 24-70mm f/2.8L II and Canon 70-200mm f/2.8L IS II become 17-50mm f/2 and 50-142mm f/2 high-speed zooms, respectively. Lenses like the Canon 50mm f/1.2L become an effective 35.5mm f/0.9 lens.
Please note that these effective focal ranges quoted by Metabones are in full frame terms. You still have to consider the 1.5x crop factor of your APS-C Sony camera (or APS-C Sony mode), making that 35.5mm equivalency read more like 53.25mm. This is the point of the Speed Booster. It allows the full frame lens (in this example, a 50mm) actually produce a field of view closer to 50mm rather than the 75mm effective view you'd get with a straight (non-boosting) adapter. In addition to this is the aperture boost.
This adapter is ideal for those who want to use their full frame Canon lens collection on Sony E mount cameras that have either APS-C sensors, Super 35 sensors, or ASP-C/Super 35 modes without sacrificing angle of view.
