Metabones introduces a new line of Canon EF-to-Fujifilm X adapters featuring TruePDAF autofocus optimisation and cinema-grade Speed Boosters, promising significant improvements for videographers and photographers alike.
Metabones has returned with a fresh line-up of Canon EF-to-Fujifilm X adapters, arriving only weeks after the company introduced updated EF-MFT products. The new quartet comprises the EF-X mount T Speed Booster Ultra 0.71x II+, the EF-X mount T Smart Adapter II+, and cine-branded versions of both. Metabones says the products are built around its TruePDAF system, which is designed to improve phase-detect autofocus on Fujifilm bodies to a level it says has not previously been seen with adapted lenses.
The company’s latest claim rests on a firmware library of more than 100 Canon EF-mount lenses. On compatible Fujifilm X-series cameras with phase-detect autofocus support, including the X-H line, X-T2 and later, and X-Pro2 and later, Metabones says TruePDAF can optimise focus behaviour for supported lenses. It also stresses that non-listed lenses can still use PDAF through the adapters, although performance will not necessarily match the company’s best-case examples.
The most technically ambitious model is the Cine Speed Booster Ultra 0.71x II+. Metabones says its five-element, four-group optical design reduces the effective crop factor of Fujifilm X cameras from 1.5x to 1.07x. The company argues that this lets full-frame EF lenses deliver brighter effective apertures, citing examples such as Canon’s 24-70mm f/2.8 becoming a 17-50mm f/2 equivalent and a 50mm f/1.2 turning into a 35.5mm f/0.9. Metabones says Fujifilm’s 40-megapixel APS-C bodies should make the strongest use of the adapter’s image quality.
Pricing places the cine Speed Booster at $699, with the standard Speed Booster at $649. The no-optics Smart Adapter II+ is priced at $399, while the Cine Smart Adapter II+ costs $449. The cine models add a positive-lock mechanism intended to stop lens movement during focusing or zooming, a feature Metabones says is aimed at video work. Owners of the original EF-X adapters can contact the company about an upgrade path to the II+ version, which requires an internal circuit swap.
