2.Compatibility
Camera compatibility: This product supports all G mount cameras in
the market.
1) Cameras with PDAF (e.g., GFX100 and GFX100S): PDAF works. AF
speed and accuracy is relatively better.
2) Cameras without PDAF (e.g., GFX50S, GFX50R and GFX50S II):
Contrast AF only. AF performance is poorer and more error prone.
Lens compatibility: This product supports all C645 lenses. All of them
except Apo-Makro-Planar T* 4/120 support auto focus. All of them
support IBIS when working on cameras with IBIS function, e.g., GFX100,
GFX100S and GFX 50S II).
3.Settings
Lens installation: Align the red dots on both mounts of the lens and
the adapter. Then insert the lens and turn it until the focus indication white
line on the lens is exactly at the top direction and the lens release button
on the adapter pops up.
Full frame/Medium format selection: Please make sure the 35mm
mode is set to Off in the camera menu. If it’s set to On or Auto, the
3
pictures may be cropped which isn’t necessary since we are using medium
format lenses.
AF/MF selection: C645 lenses don’t have AF/MF switches. We use
their aperture ring instead. When it’s turned to the minimum stop, i.e.,
maximum F number, the adapter informs the camera to enter MF mode.
Otherwise, it’s in AF mode. The AF/MF switch on the camera can always be
set to AF.
Adapter configuration file: Connect the adapter to a computer
using the cable included. You will see a drive named FRINGER. There is a
file named SETTINGS.INI in the root folder. It’s in standard INI file format.
Don’t modify it unless you understand how to do so. If you want to restore
its content to default, just remove it. The adapter will regenerate a default
version next time when the adapter is used on a camera.
Aperture setting: Aperture may be set through the aperture ring on
the lens. But if it’s in MF mode, the aperture ring is set to the minimum
stop. In that case aperture can be set through command dial on the
camera. Meanwhile, if you set the value of “LensApertureRing=” in
SETTINGS.INI to 0 (the default value is 1), aperture is always set through
4
command dial on the camera.
Shutter speed setting: Manually setting shutter speed is
suggested! Setting shutter speed to auto in AF modes may cause the
aperture blades move frequently with noise and flashing of LCD or EVF
when environment brightness changes. That may interfere with view
finding. Be noted, when preview EXP./WB in manual mode in camera
menu is set to Off, you need to use MF mode to avoid the issue.
AF settings: Because of the limitation of the old lenses’ design, AF-S
is suggested. On cameras with PDAF support, e.g., GFX100 and GFX100S,
AF-C may work, too. But don’t expect good performance. On other
cameras, please don’t use AF-C mode. In both cases, Face/Eye AF is
supported. To get a balanced AF performance in terms of success rate and
accuracy, setting focus points to medium size is suggested. Before
releasing the shutter, you may focus multiple times on the same object to
improve accuracy. Meanwhile, please avoid using focus points in columns
close to the left and right edge.
Image stabilization settings: To use IBIS on cameras like GFX100,
GFX100S and GFX50S II, make sure the value of “FocusBracketing=”in
5
SETTINGS.INI is set to 0 (the default value). Don’t forget to turn on IS in
camera menu.
Focus bracketing settings: To use focus bracketing, please set the
value of “FocusBracketing=” in SETTINGS.INI to 1 (the default value is 0).
Be noted that please always use AF to set the working range and start
position. If you manually turn focus ring of the lens, focus bracketing
function won’t work properly.
4.Firmware update
You need a PC or MAC and a USB Micro B cable (already included) to
upgrade the adapter.
1. Get the adapter off the camera. Connect it to your computer.
2. Find a new drive named “FRINGER” and copy the new firmware to it.
3. Wait for about 20 seconds. The adapter will disconnect itself and
reconnect automatically.
4. Check the installed firmware version (VERSION.TXT on the adapter)
For example:
Before:
6
after:
Be noted: If nothing happens when the adapter is connected to the
computer, it’s probably caused by a bad USB cable. Please try another one.
5.Warranty service
We provide 1-year limited warranty. You may contact the seller from
whom you ordered the adapter to get warranty service. If the issue was
caused by abnormal usage or it’s out of the free warranty period, there is
a paid repair service. In any case, you may contact us for the service:

2.兼容性
机身兼容性。本品兼容所有已经上市的 GFX 机身。
1)带有相位对焦功能的机身(如 GFX100 和GFX100S):使用相位
对焦,AF 的速度和精度相对更好。
2)其它机身(如 GFX50S,GFX50R,GFX50S II 等):使用反差对
焦,由于镜头能力限制,更易出现合焦慢、合焦误差等现象。
镜头兼容性。本品兼容所有的 Contax 645 镜头,除了 Apo-Makro-
Planar T* 4/120 外均支持自动对焦,所有 C645 镜头在带有机身防抖的
机身(GFX100/GFX100S/GFX50S II 等)上均支持机身防抖。
3.设置说明
镜头安装:将镜头后卡口上的红点和转接环 C645 卡口上的红点对
齐,插入镜头并旋转,直到镜头上的对焦指示标线到达转接环与相机的
正上方,并且转接环上的镜头释放钮弹起为止。
画幅选择:请务必在相机菜单中将 35mm 模式设为“关”,否则会出
现画幅裁切。
AF/MF 选择:由于 C645 镜头没有 AF/MF 开关,我们使用镜头光圈
环的最小光圈档位(最大 F值的那一档)指定 MF 模式,如果光圈环在
9
此档位上,转接环会通知机身进入 MF 模式,而无需设置机身上的
AF/MF 开关。
转接环配置文件:本产品支持用户使用配置文件中的软开关来指定
某些高级功能是否启用。用附送的 USB 电缆将转接环连接到电脑,会出
现名为“FRINGER”的磁盘驱动器,在其根目录下有一个名为 SETTINGS.INI
的文件,格式为标准的 INI 文件。除非你知道如何改动这个文件的内
容,否则请不要修改。如果文件被改乱了并且你不知道如何恢复,可以
删除此文件,转接环会在下次在相机上工作时自动生成缺省的版本。
光圈设置:缺省情况下,可以使用镜头光圈环设置当前光圈值,但
如果使用 MF 模式(光圈环在最小光圈档位),则改用机身拨轮设置光
圈。如果在转接环配置文件中将“LensApertureRing=”的值设为 0(缺省
值为 1),则总是使用机身拨轮设置光圈。
快门设置:建议手动设置快门速度!富士无反相机有一套独特的光
圈控制策略(GF 镜头也是如此),在 AF 模式下,如果快门速度为自动,
则在取景过程中遇到环境光线变化时,光圈叶片可能会频繁动作、带来
噪音,同时,取景器或 LCD 上的画面会有闪烁,对取景造成干扰。通常
手动设置快门速度可以部分避免此问题。注意,在关闭“手动模式下预览
曝光”的情况下,只有改用 MF 模式才能避免此问题。
10
对焦设置:由于镜头 AF 性能限制,建议仅使用 AF-S,对于 GFX100
和GFX100S 等带相位对焦能力的机身,可以谨慎使用 AF-C(效果有
限),对于其它机身,请勿使用 AF-C 模式。无论哪种情况,脸部/眼部
对焦都可以正常使用。建议使用中等大小的对焦点以获得合焦成功率和
合焦精度上的平衡。在释放快门前,必要时可以对同一目标进行二次对
焦以减小误差,同时,避免使用左右两侧边缘几列的对焦点,由于老镜
头的像差比较严重,造成越是大光圈、越是离中央几列距离远的对焦
点,合焦误差越大。
由于 C645 镜头的设计比较老旧,跟不上现代无反相机的要求,如果
出现 AF 速度、精度无法满足您的需求的情况,请改用 MF 模式。
防抖设置:对支持机身防抖的机身如 GFX100/GFX100S/GFX50S II,
如需使用机身防抖,请确保转接环配置文件中的“FocusBracketing=”值为
0(缺省值),然后在机身菜单中打开防抖,机身防抖可以正常工作。
对焦包围设置:如需使用对焦包围功能,请将转接环配置文件中的
“FocusBracketing=”值改为 1(缺省为 0)。注意,在设置对焦包围范围、
起始焦点位置时,只能用 AF 驱动,不要手动调整镜头对焦环,否则对
焦包围功能不能正常工作。

4.固件升级
您需要一台 PC 或者 Mac 电脑以及一根标准的 Micro B 类型的 USB
电缆(已经附送)来进行固件升级。
1. 确保转接环没有装上机身、没有安装镜头,连接转接环和电脑
2. 在电脑上找到名为“FRINGER”的驱动器,把新固件文件拷贝进去
3. 等待 20 秒左右,转接环会自动断开与主机的连接然后重新连接
4. 打开重新出现的“FRINGER”驱动器,检查版本是否已更新(在
VERSION.TXT 文件中的版本号)
例如:
升级前:
升级后:
注意:如果转接环连接电脑后“FRINGER”驱动器没有出现,一般是
电缆的问题,可以换一根重试。
