I currently use a Canon 700D and own a Sigma 18-35mm f/1.8 in Canon EF-S mount. I’m considering buying a used Fujifilm X-T1 and would like to know whether there is an EF/EF-S to Fujifilm X adapter that preserves electronic functions such as autofocus, metering, and image stabilization if supported by the lens. Is full functionality realistic, or should I expect limitations compared with native Fuji lenses?

There are now several "smart adapters" for EF-FX that allow AF and OIS to work: Fringer, Kipon, Steelsring, and Viltrox. Viltrox is the cheapest. Kipon Baveyes is the most expensive.

If you already own multiple compatible lenses, getting an adapter may be worthwhile. Otherwise, for both price and performance, you are better off with native lenses.

  • Compatible lenses should work reasonably well, but not as well as native lenses. Firmware updates have been known to introduce problems with previously compatible lenses. Incompatible lenses can be expected to be plagued with problems.

  • OIS and AF aren't as good with adapted lenses as with native lenses.

  • Most of them release new firmware updates occasionally: Fringer, Kipon, Steelsring, and Viltrox.

  • The Kipon Baveyes has a 0.7x focal reducer built in. It's the most expensive, and there is no lens compatibility list. It is also made of a hard brushed metal that will abrade metal from your lens and camera mounts.

  • You can search YouTube for demo videos.

Some lenses to illustrate variable compatibility among adapters:

  • Sigma 18-35/1.8 Art – I have not used this lens.

    • Is on the Fringer compatibility list.
    • Not on the Viltrox compatibility list.

  • Canon EF 40/2.8 STM – Works well with Fringer and Steelsring adapters. Reports incorrect aperture with Viltrox adapter, despite being listed as compatible.

  • Canon EF-S 24/2.8 STM – Works very well with Fringer, Steelsring, and Viltrox adapters. Fast and responsive, but loud (kind of like the XF 35/1.4).

  • Canon EF-S 18-135/3.5-5.6 IS USM

    • Works best with Fringer adapter.
    • Works reasonably well with Steelsring adapter.
    • AF does not work with Viltrox adapter. Not sure about IS.

  • Tamron 28-300/3.5-6.3 ??? VC – Autofocus does not work with any adapter I've tried. Can be used as an image-stabilized manual-focus lens with the Fringer adapter.

I have tried other adapter-lens combinations, but do not recall results. Generally, as noted above, if it's on the compatibility list, it usually works well. Otherwise, it's pretty miss or miss, especially with third-party lenses.

Yes—there are EF-to-Fujifilm X “smart adapters” that can provide electronic communication for Canon EF and many EF-S lenses, including functions like metering, autofocus, and optical stabilization where supported. Brands mentioned by users include Fringer, Kipon, Steelsring, and Viltrox.

However, don’t expect native-lens performance. AF and stabilization typically work, but usually not as well as with Fujifilm X-mount lenses. Compatibility also varies by specific lens and adapter firmware, and updates can sometimes improve or break support. In practice, some lenses work reasonably well, while others may be unreliable.

So the answer is: yes, adapters exist, but “full functionality” is not guaranteed in the same way as on your Canon body. If you already own several compatible EF/EF-S lenses, an adapter can make sense. If this is mainly for one lens and you want the best performance, native Fuji lenses are usually the better choice.
