Fringer EF-FX Adapter Firmware 3.20 and 1.40 Released


Fringer released a firmware for the Fringer EF-FX Pro/EF-FX and Fringer EF-FX Pro II/EF-FX II that you can download here.

For Gen2, i.e. EF-FX Pro II and EF-FX II, V1.40 firmware is released.

  1. Fixed PDAF issues for some lens of the following models: Lens didn’t get recognized by the adapter due to different lens firmware version.
  2. Bug fixed: Under some circumstances in video mode, the video recorded may suddenly become brighter or darker at 0.25 seconds from the beginning.
  3. Fixed compatibility issues with X-A7 camera. Be noted, since X-A7 is equipped with a none X-Trans CMOS, its AF performance is poorer when using EF mount lenses. Please use MF mode if necessary.
  4. Introduced smooth video AF for the following lenses.
  5. Added following lenses to the tested and optimized lens list:

Unfortunately, the resources of Gen1 adapters are almost used up. Begin with V3.20, we will not add new lens support along with the new firmware for Gen2. In other words, no new lens data, only bug fixes.
