For Gen2, i.e. EF-FX Pro II and EF-FX II, V1.40 firmware is released.
For Gen1, i.e. EF-FX Pro and EF-FX, V3.20 firmware is released.
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.
Please visit our official website to download the new firmware, release notes and user's manual.
To upgrade your adapter, connect it to a computer through a USB Micro B cable. Copy the corresponding firmware (.BIN file) to the emerged drive named "FRINGER". Wait for 20 seconds. The adapter will upgrade itself.
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 and EF-FX II, you need firmware file named EFX2_****.BIN. Using the wrong file will not damage your adapter. But it will not install.
