Metabones EF to E Mount T Cine Speed Booster ULTRA Rental

Overview

The Metabones EF to E Mount T Cine Speed Booster ULTRA is a cinema-styled electronic adapter that 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 while allowing you to use your favorite Canon EF mount 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. For example, your Canon 40mm f/2.8 STM lens becomes an effective 42.8mm with this Speed Booster on an APS-C sensor instead of the 60mm effective view you'd have with a straight adapter. 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. Lastly, the Metabones Canon EF Lens to Sony E Mount camera T Cine Speed Booster ULTRA supports Smooth Iris functionality in certain lenses (see the Notes tab for more). 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.
