Firmware v2.00 released for Fringer EF-FX (Pro) II adapters

We are glad to release a new firmware, i.e. version 2.00, for Fringer EF-FX Pro II and EF-FX II adapters. Some issues that bothering us for a long time have finally been fixed. We suggest every user upgrade their adapter to this version.

Detailed information:

Version 2.00

1. Bug fixed: When cameras equipped with X-Trans IV CMOS (X-T3, X-T4, X- S10, etc.) work with some of fast, telephoto and macro lenses, there may be repeatedly AF hunting when aperture isn’t wide open. 

2. Bug fixed: On some cameras like X-T3, after a photo was taken, if playback button is pressed and then shutter button is half-pressed in short time, the camera may be frozen until the adapter or the battery is taken off the camera.

3. Bug fixed: There may be abnormal chromatic aberration on photos taken by some lenses that haven’t been optimized.

4. Fixed PDAF issues for some lenses of the following models: Lens didn’t get recognized by the adapter due to different lens firmware version.

  • SIGMA 24-35mm F2.0 DG HSM A015

5. Fixed IBIS issues for the following lenses:

  • EF-S 60mm F2.8 Macro USM
  • IRIX 15mm F/2.4

6. Added following lenses to the tested and optimized lens list:

  • Sigma 14mm f/1.8 DG HSM A017
