   4. The IS control logic has changed. Now the lens IS and IBIS automatically exclude each other and can be selected on the fly (controlled by the IS switch on the lens).
   5. Lens with IS, the IS switch on the lens is ON: Lens IS is continuously activated and IBIS is automatically turned off. At this time, the vibration reduction setting in the camera menu is automatically set to ON (grayed out and cannot be changed)
   6. Lens with IS, the IS switch on the lens is OFF: Lens IS is turned off. The vibration reduction setting in the camera menu determines whether to activate IBIS. ON activates IBIS and OFF turns it off.
   7. Lens without IS: The vibration reduction setting in the camera menu determines whether to activate IBIS.
   8. When the camera is powered on and in shooting mode, if the IS switch on the lens is changed from OFF to ON, the lens IS is activated and IBIS is turned off; if the IS switch on the lens is changed from ON to​ OFF, the lens IS is turned off and IBIS is turned on (depending on the vibration reduction setting in the menu).
   9. When the lens IS is activated, the camera will automatically turn it off to save power when the camera is switched to playback mode or enters the menu. It will turn it on again when the camera returns to shooting mode.

    10. Added support for lenses without electronic contacts. Unlike Nikon FTZ adapter, when

    4

    installed on Fringer EF-NZ adapter, lenses without electronic contacts also get the green square focus indication at the focus point position.

    When this function greatly helps a lot of manual lens users, it has a drawback.

    The Non-CPU Lens Data menu item doesn’t work anymore.

    Without correct focal length data, the IBIS function of certain Zcameras, e.g.

    Z6 and Z7, doesn’t work properly.

    To fix this, we added manual lens focal length input function.

    Usage: When the adapter is installed on the camera and no electronic lens is installed, turn on the camera and set it in photo shooting mode. (We use a 135mm manual lens as a sample)

    1. Half press and hold shutter button (or AF-ON button). Press AFL button (Center of sub-selector by default) for 3 times. Release shutter button (or AF-ON button).
    2. Now, there should be a F1.1 on the screen. It means we are now inputting the first digit of the focal length number.
    3. Press AFL button once. Now the Fnumber displayed on the screen represents the value currently stored. F10 means 0, F11 means 1, …, F19 means 9.
    4. Press AFL button for multiple times until current digit reaches the value you want.

    Each time after it’s pressed, current digit will increase by 1. For example, we need to s​et it to 1 for a 135mm lens.

    5. Half press shutter button (or AF-ON button) and release it. Now, there should be a F2.2 on the screen. It means we are now inputting the second digit of the focal length number.
    6. Repeat step 3 to 4 to set the second digit. For example, we need to set it to 3 for a 135mm lens.
    7. Half press shutter button (or AF-ON button) and release it. Now, there should be a F3.3 on the screen. It means we are now inputting the third digit of the focal length number.
    8. Repeat step 3 to 4 to set the third digit. For example, we need to set it to 5 for a 135mm lens.
    9. Half press shutter button (or AF-ON button) and release it. Now, there should be a F1 on the screen. It means the focal length number has been stored and AF-ON button AFL button (by default)

    5

    the camera has returned to photo shooting mode.

    During the above process, you may cancel at anytime by turning of the camera.

    In that case, the focal length value stored won’t be changed.

    After a new value is set, you may take a photo and check the focal length field in the EXIF.

    The value is stored in the adapter permanently and won’t be affected by turning off the camera or removing the battery from the camera.

    How to upgrade: 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.
    3. Wait for 20 seconds. The adapter will disconnect itself from the computer and reconnect.

    If it doesn’t reconnect automatically, you may disconnect the USB cable and reconnect it manually.

    4. Check installed firmware version (VERSION.TXT on the adapter)

    For example: Before upgrade:

    After upgrade:

    Troubl​eshooting: 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!

    When the adapter is installed on the camera, you may also check the its version through camera menu function, i.e. “SETUP MENU” → “Firmware version”. The numbers follow the “MA” is the adapter’s firmware version.
