Metabones Adds Native AF and Smooth Iris to EF Mount Speed Boosters and Smart Adapters1 min readReading Time: < 1 minute
Without a double the Metabones Speed booster and Smart adapters have been the most popular adapters for video shooters in the last few years. Their optical and build quality is outstanding, and although they do cost a few pennies, in my experience with the Smart Adapter Mark IV (EF to E) it has been well worth it. The success of the Metabones optical adapters have spawned a whole new range of similar, but more budget products from various Asian manufacturers, but most of them have not been able to match the quality of the Metabones adapters. Extremely popular with Sony A7s II, FS7 and FS5 shooters who have a ton of Canon EF lenses, Metabones just released a major firmware update 2.3, which adds Native AF support as well as Smooth Iris to their range of EF mount Speed boosters.
Metabones has already added fast EF lens autofocus to its Micro Four Thirds Mount Speed Boosters and Smart Adapters last year. With this speedy advantage now extended to E-Mount, 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.
