What's in this update

  1. Bug fixed: When cameras equipped with X-Trans IV CMOS (X-T3, X-T4, X- S10, et​c.) 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. Issue fixed: When using some Fmount lenses with certain internal defect, it may cause the camer​a blackout and reboot repeatedly. Now it works normally with those lenses with that defect.
  4. Fixed PDAF issues for some lenses of the following model: Lens didn’t get recognized by the adapter due to different lens firmware version.
  5. TAMRON SP 70-200mm F/2.8 Di VC USD A009
  6. Added following lenses to the tested and optimized lens list:
  7. SIGMA 30/1.4 EX DC HSM
  8. TAMRON 70-210mm F4 Di VC USD A034
  9. SIGMA 24-35mm F2.0 DG HSM A015
