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)

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.
