Discover how to get the most out of your Canon EF lenses on your Fuji X frame! With the Viltrox EF-FX2 PRO adapter, you can combine the advantages of the two systems: you keep the automatic focus, the transmission of EXIF ​​data, and you can even give your pictures a new perspective with +0.71× magnification with the built-in optical elements. Professional design, precise fit and future-proof firmware update — an ideal choice for both film and photo work.

The Viltrox EF-FX2 PRO lens adapter is an active "speed booster" adapter that makes Canon EF / EF-S lenses compatible with Fujifilm X-mount cameras. The adapter is not just a mechanical transition: thanks to its optical elements, it provides a 0.71x magnification (ie, the effective angle of view of the lens is wider on the APS-C sensor), and it also offers a brightness increase (~1 stop), so you can make better use of the capabilities of the lenses.

Automatic communication
It retains autofocus, transmission of exposure and aperture information, and lens image stabilization, if supported by the lens.

Aperture control
A built-in aperture ring allows for manual aperture travel, giving you great flexibility for creative settings.

Firmware update
It can be updated via the USB-C port, so it can be further developed with newer software fixes and supports.

Precise construction
Aluminum alloy and chrome-plated copper details ensure a strong, stable fit between the frame and the lens.

Optical elements
4 optical members in 4 groups to maintain image quality and minimize distortion.

Compatibility
For using Canon EF / EF-S lenses with Fujifilm X-system frames (e.g. X-T, X-H, X-Pro).

Durability
Durable construction, stable bayonet fit, secure locking mechanism for optical and mechanical stability.

Optical advantage
Thanks to the 0.71× magnifying element, the APS-C sensor makes better use of the optical performance of the lens (wider angle of view + extra light).

Restrictions / Warnings
According to some users and tests, focus pumping, slower AF, and lack of IBIS (camera internal stabilization) support may occur with certain lenses (mainly with longer telezooms).
