Fringer EF/FX adapters' new firmware (V1.20 for Gen2 and V3.0 for Gen1) is available

It's been a while since last firmware released for both Gen1&2 EF/FX adapters. This time we bring you the V1.20 for Gen2 and V3.0 for Gen1.

V1.20 (EF-FX Pro II)

V3.00 (EF-FX Pro & EF-FX)

  1. BUG fixed: When doing contrast AF under circumstances like low light, some new lens models, e.g. SIGMA50-100/1.8, may be error prone and result in low successful rate.
  2. Fixed PDAF issues for some of the following lens models: Lens didn’t get recognized by the adapter due to different lens firmware version.
    • SIGMA 120-300/2.8 Sports
  3. AF performance of following lenses have been improved further.
    • Sigma 18-200/3.5-6.3 OS Contemporary
    • EF85/1.8 USM
    • EF70-200/2.8L USM
    • EF70-200/2.8L IS USM
  4. Added following lenses to the tested and optimized lens list:
    • EF28/1.8 USM
    • EF35/2
    • EFS60/2.8 Macro USM
    • EF70-200/2.8L USM + 1.4X
    • EF70-200/2.8L USM + 2X
    • EF70-200/2.8L IS USM + 1.4X
    • EF70-200/2.8L IS USM + 2X
    • TAMRON16-300/3.5-6.3 VC PZD
    • TAMRON SP 35-150/2.8-4 Di VC OSD A043
    • YONGNUO50/1.4 (PDAF performance may not be stable due to poor aperture motor of the lens. Try setting shutter speed manually and use MF mode if necessary.)

Tamron SP 35-150/2.8-4 which has newly arrived market looks very promising for adapting. It performs quite well on Fujifilm X mount. As a 4.3x zoom lens, it has inevitable LaCA. Now the new adapter firmware also fixed that by providing correction data to the camera.

Be noted, make sure you download the correct file for the corresponding product. For Gen1, i.e. EF-FX Pro and EF-FX, you need firmware file named EFFX****.BIN. For Gen2, i.e. EF-FX Pro II, you need firmware file named EFX2_****.BIN. Using the wrong file will not damage your adapter. But it will not install.
