Cool: Metabones adds “Native” AF and Smooth Iris to EF Mount Speed Boosters and Smart Adapters by Firmware
Metabones just released a new firmware update for Canon EF to E-mount Smart adapters and Speed Boosters: “EF-Mount lenses are now capable of focusing quickly across the widest variety of mirrorless cameras with trusted Metabones precision and reliability. The smooth iris feature slows down the movement of the electromagnetic aperture diaphragm so that video footage transitions smoothly when the aperture changes, with reduced tick noise from the lens. The latest Canon and Tamron SP lenses have special support for this feature and Metabones® makes use of it if the lens supports it.”
