  18. ZEISS Otus 55mm f/1.4 Apo Distagon ZE
  19. ZEISS 135mm f/2 Apo Sonnar T* ZE
  20. Bug fixed for EF85/1.4L IS: In some circumstances AF search may be very slow.
  21. Software switch​ functions added. When connected to a computer through a USB cable, there is a file named SETTINGS.INI in the root folder of the adapter.

It’s in format of ordinary INI files. Don’t modify it unless you know how to do that. If you want to restore it to default, just remove it. The adapter will re-generate it when the next time it works on a camera body.

  1. Focus bracketing support added. By default, it isn’t turned on. To turn it on, edit SETTINGS.INI and change the value of “FocusBracketing=” from 0 to 1.

Be noted:

  1. When setting focus range and begin position, don’t manually turn focus ring! Always use AF to drive focus point to the position you want. Or the focus bracketing function may not work properly.
  2. When “FocusBracketing=” is set to 1 in the SETTINGS.INI, the adapter is set to native mode and some functions of the camera may change, such as the 35mm auto mode will not crop automatically, IBIS may not work properly any more, etc.
  3. User option for power-off behavior added. On one hand, some lenses with external focus design such as some STM lenses may not be convenient to be stored in a bag when its AF isn’t on infinity. Moving AF to infinity automatically when powering off (or switching to playback mode) is preferred. On the other, some of them, e.g. EF85/1.2L II, may have very heavy front elements so that the experience of moving it to/​from infinity every time switching the camera to/from playback mode is really bad. Thus, it’s better to

let the user decide.

We have added an option item named “PowerOffInfinity” to SETTINGS.INI.

Default value (0): only some STM lenses, EF50/1.4, Sigma 70/2.8 ART, etc. will be moved to infinity when powering off/switching to playback mode.

Value 1: all lenses will be moved to infinity.

Version 1.00 Initial version

You need a PC or MAC and a USB Micro Bcable to upgrade the adapter.

  1. Connect the adapter to your computer.
  2. Find a new driver named “FRINGER” and copy new firmware to it.

After upgrade:

Troubleshooting: Some of the cables in the market are for charging only and not suitable for data transfer. Thus, if you can’t find the “FRINGER” drive when adapter is connected to the computer, check your cable!

You may also read the adapter’s firmware version by Fujifilm’s method, i.e. press and hold DISP button before powering on the camera. The “Lens version” on the screen is actually the adapter’s firmware version.
