Fringer EF-FX Smart Adapter Coming in Early 2018

Sounds like Fringer is making some progress with their Fringer EF-FX Smart Adapter for Fujifilm cameras. Some of the smaller adapter manufacturers are really amazing and dedicated to hacking camera systems. Hopefully, Fringer gets it dialed in. Below is an excerpt from Frinderdev:

After almost a month’s research and development, Fringer EF-FX smart adapter prototype’s PDAF performance has been further improved.

Unlike Sony E mount cameras, Fujifilm X mount is quite complex in PDAF support. More than two years ago, when A7r2 introduced phase detection AF (PDAF) for adapted lenses for the first time, I spent a night to find out the key mechanism and in very short time let my Contax N-E adapter become world’s first third party smart adapter supporting PDAF on mirrorless. Now I finally find the way to make X cameras do the same when adapting EF lenses. All the PDAF points on CMOS, not only the central one, but also the others around it, are all working properly, whatever the lens is wide or telezoom or prime and whatever the aperture is set wide open or stopping down.

Although the firmware of smart adapter for GFX50s can be easily modified to support X mount as what some other smart adapter manufacturer probably is doing , it doesn’t support PDAF. Compared with CDAF (contrast detection AF), PDAF is a performance leap. Thus, I developed the new version specifically for X mount. I made a short video to demo the AF-C zone focusing performance when PDAF is enabled. The lens is Sigma 30/1.4 art (for EF mount) and the camera is X-T2. Remember that S30/1.4A has a bad reputation for its slow AF speed.

In addition to that, I also did some real field tests. Using a EFs 55-250/4.0-5.6 IS STM lens and X-T2 camera, I tried continuous shooting on a moving vehicle towards the camera. I set the AF mode to zone and AF-C, continuous shooting mode to CH, and shutter mode to electronic only. The lens was at 250mm/F5.6.

I shot 34 photos in less than 4 seconds with a rough speed of 10 frames per second.

Those shots were used to make the moving gif below and the adapter currently has about an 80% hit rate, which is impressive.

The Fringer EF-FX Smart Adapter is expected to be released in early 2018.
