Fringer EF-FX Smart Adapters’ AF Performance Improved Again (Firmware V1.30)



Fringer released a new update for the popular Fringer EF-FX Smart Adapter and if you missed out on the first batch a new one will be coming very soon. They expect to have stock of the Fringer EF-FX in late March or early April according to the FringerDev Blog. You can download the update here and see the details below.

We found a new way to improve EF lenses’ phase detection AF accuracy on X mount cameras. Integrated in the new firmware (v1.30), the following lenses has been re-optimized according to the new method.

    1. EF 35/1.4L II
    2. EF 85/1.4L IS
    3. EF 100/2.8L IS
    4. EF 135/2L
    5. EF 16-35/2.8L II
    6. EF-S 55-250/4-5.6 STM
    7. Sigma 18-35/1.8 ART
    8. Sigma 50-100/1.8 ART

The new firmware is the most important upgrade since the adapter being released and is recommended for all Fringer EF-FX Pro adapter users. The newly introduced lens data will let all the phase detection AF points, e.g. the green ones on a X-T2 as shown below, locking on targets not only fast but also more accurately. And that’s the key for AF performance of AF-C and video recording, too. Other lenses may also be re-optimized in the future if necessary.



Meanwhile, the new firmware (v1.30) has following improvements.
