The Metabones Canon EF Lens to Sony E-Mount Camera ULTRA Speed Booster improves upon the original Metabones Speed Booster with a 5 element/4 group optical design that incorporates ultra-high refractive index tantalum-based glass for improved sharpness and reduced distortion and vignetting. The Speed Booster ULTRA allows a full frame Canon EF lens to be mounted to an APS-C format E-Mount camera and in doing so, increases the angle of view and the maximum aperture by approximately one f/stop.
When a lens intended for full frame sensors or 35mm film is mounted to a camera with an APS-C sized sensor, it transmits a larger area of light than the smaller sensor was built to accept and therefore the effective angle of view of the lens increases. The Speed Booster condenses light from the lens and projects it onto the APS-C sensor allowing the sensor to utilize all of the lens' light and effectively reduces the crop factor of and APS-C E-Mount camera from 1.5x to 1.07x, producing a full-frame angle of view with an APS-C sensor. A corresponding increase in the maximum aperture of one f/stop makes the lens more effective in low-light situations and able to create a shallow depth of field.
Automatic exposure information is communicated by the speed booster and controlled from the camera body and partial autofocus is supported for post-2006 Canon-brand lenses. No external power source is required as the speed booster is powered by the camera.
Metabones Speed Boosters are quality made, using precision-machined brass with chromium plating on both the camera body and the lens side of the booster in order to ensure smooth mounting, quality aesthetic and durability. This adapter has a detachable tripod foot that is compatible with Arca Swiss, Markins and Photo Clam ball heads.
These speed boosters are only fully compatible with mirrorless cameras housing APS-C or smaller image sensors. They will physically fit the Sony A7/A7R/A7S full frame mirrorless cameras but the camera must be set in Crop Mode to fully support the speed booster's functions.
