Fringer EF-NZ （Model FR-NZ1）User’s Manual
（Firmware v1.30）
1. Introduction
This adapter is compatible with Canon EF/EFS mount and Nikon Z mount protocols.
It can control lens’ aperture electronically, auto focus and report lens information for EXIF
recording. Most EF/EFS lenses manufactured by Canon and third parties, e.g. Sigma,
Tamron, etc., get similar phase detection AF performance to that of adapting Nikon F
mount lenses to Z mount through Nikon FTZ adapter.
Both bayonets of EF and Z mount are made of brass. The body and tripod mount are
made of alloy. All these parts are made by high precision CNC and very solid and durable.
The professional light extinction design inside the adapter will make sure the optical
performance of the lens is maximized.
A removable tripod mount is included. It’s useful when medium sized lenses are used
or when the whole setup is to be installed on a gimble. But if you don’t need it, you may
remove it by uninstalling the two screws under it using the L-wrench which is also
included. When you reinstall it, please be noted that don’t use too much force. Or the
thread may be damaged.
There is a Micro USB plug for a firmware update purpose near the tripod mount. Read
section 4 for more details.

This adapter works with Z mount cameras including Z6, Z7, Z50, and theoretically
other Z cameras to be released in the future. If compatibility issues are found when a new
Z camera comes, we may fix it through a new firmware update.
Begin with firmware 1.20, the adapter is compatible with almost all EF/EFS mount
lenses manufactured by Canon and major third parties except some rare cases. Aperture
control works for all AF or MF (such as TS-E) lenses. Phase detection AF works for all AF
lenses. Whatever which AF modes, i.e. AFS, AFC, face and eye detection focus, and still
photo or movie mode you use, it’s just like adapting an F mount lens through the FTZ
adapter.
However, because the EF/EFS mount is a huge family, we haven’t tested all lenses.
Thus, if you encounter any compatibility problem, please let us know. As long as we can
find a lens sample to do tests, the problem may be solved through a firmware update.
3. Function descriptions
The basic usage is similar to adapting a Nikon F mount lens through the FTZ adapter.
3.1 Installation and image area setting
We suggest to install the lens to the adapter first. Then install the adapter to the
camera. When you need to change the lens, please power off the camera first. Then
replace the lens and power on the camera again.
When an APS-C lens is installed, the adapter will not force the camera to use DX format.
Instead, the choice is yours. But if you set the image area to FX, there may be dark corners,
distortions, etc. That isn’t the malfunction of the adapter but limitations of APS-C lens
itself.
3.2 Lens built-in IS and camera IBIS functions
This adapter fully supports both IS (or OS, VC, etc.) function of the lens and IBIS
function of the camera. But they cannot work together.
IBIS is controlled by the camera menu. As long as the menu item “Vibration Reduction”
is set to “ON”, it keeps working.
Lens IS function is controlled by the IS switch on the lens. As long as it’s at “ON”
position, it keeps working.
The two IS functions are independent. Don’t turn on both at the same time. Or the

function will fail. For the latest generation of Canon IS lenses and all tele-lenses longer
than 300mm, lens IS function is recommended. For all the other lenses, IBIS is preferred.
When lens IS function is activated, if you power off the camera, the operation will not
finish until the IS module is parked. That may cause a delay of 2 or 3 seconds. Of course,
you will not notice it unless the camera is turned on immediately after being turned off.
3.3 AF settings
All the AF modes, i.e. AFS, AFC, AFF (for video), MF (please set AF/MF switch on the
lens to MF), are supported. You may use AF area of Single-point, Dynamic-area, Wide-area
and Auto-area. But please be noted, if AF area of Pinpoint is used, some lenses may not
perform well. In that case please use Single-point instead. You may also use face/eye
detection AF like using a native Nikon lens.
Some lenses may need AF fine-tune to get better
AF accuracy. However, sometimes different lens
samples of the same model may need different AF
fine-tune values. For example, we have encountered
two EF50/1.0L lenses that need +15 and -9 to get
the best AF accuracy. Thus, we don’t provide the
table of suggested AF fine-tune values anymore. Please try your lens and find the best
setting by yourself. Be noted, for some very fast lenses, e.g. EF50/1.0L, EF50/1.2L,
EF85/1.2L II, etc., correct AF fine-tune setting is a must to get sharp images.
On Z cameras, there is a Movie AF Speed setting on the menu (Custom Settings->Movie).
It may help users produce smooth focus transfer
effects. Currently, the following lenses support movie
AF speed setting. In the future, more lenses may be
added to the list. However, some relatively old lenses
may not support this function at all. They will never
be added.

3.4 settings for MF lenses without electronic contacts
Unlike Nikon FTZ adapter, when 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 Z cameras, 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 F number 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 set 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 the
camera has returned to photo shooting mode.
During the above process, you may cancel at any time 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.

4. Firmware update
You need a PC or MAC and a Micro B USB cable, i.e. some
Android phones’ data cable (not type C), to upgrade the
adapter.
1) Download new firmware from Fringer’s website.
2) Get the adapter off the camera. Make sure not to connect
the adapter with the computer while it is installed on a
camera body.
3) Plug the USB cable to the Micro USB port shown in Figure 1.
4) Connect the other end of the cable to a USB port of your PC or MAC. Then a mobile
drive named ‘FRINGER’ emerges. Open ‘VERSION.TXT’ on that drive and check the
current firmware version (the line begins with ‘Version:’).
5) If upgrading is needed, copy the downloaded firmware file, e.g. EFNZ_100.BIN, to the
drive named ‘FRINGER’. Then eject the drive. Ejection is mandatory for MAC and
optional for PC. Ignore any error messages about the drive. Wait for about 20 seconds.
The adapter would disconnect itself and reconnect. The ‘FRINGER’ drive would
appear again. If it doesn’t reconnect automatically, disconnect the USB cable and
reconnect it with the computer.
6) Check VERSION.TXT again and make sure its firmware version has changed to the new
one. You may also check the adapter’s version through the camera menu item
“Firmware version”. The number after “MA” is the adapter firmware version.
Note: Do not copy files other than the official firmware to the adapter.
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 the adapter is connected to
the computer, check your cable!
