前言
为了操作上的安全，使用本产品前请务必详细阅读使用手册与注意事项，并将手册放在
需要时容易取得的地方。如遇到不能解决的问题请通过售后电话获取技术支持。

切勿自行拆解、修改或改装。当产品由于外力原因破损，切勿触碰外露部分
或破损边缘处。
切勿放置于直射阳光下、封闭车辆中或其余高温处，否则过高的温度会使镜
片和其他部件产生伸缩变形。
不使用镜头时，请将镜头前盖盖上或置于没有阳光照射处。凸透镜反射出的
光线可能会聚集在附近物体上，导致发生火灾。
在逆光拍摄时，切勿将太阳置于画面中心，应该使太阳充分偏离画角，否则
阳光会在相机内部聚集并导致火灾或灼伤眼睛。
在使用相机内置闪光灯拍摄时，由于镜头本身会遮挡光线而产生渐晕，因此
建议您使用外设闪光灯拍摄。
安全注意事项
主要特色 注意事项
Argus系列采用内对焦设计，内对焦是现代镜头主流设计结构，可以实现多
组浮动匹配对焦，可矫正因距离变化产生的各种像差等，实现无限远和近
距离均能优质成像。内对焦的设计，也能在恶劣环境下尽量避免进灰的情
况。内对焦因长度不变，拍摄视频时不会干扰遮光斗，UV等配件，也不会干
扰模特的注意力。内对焦通过组间间隔补正，实现了低呼吸效应，适合照片
领域的同时，也比较适合视频创作。
最大光圈F0.95，大光圈带来的浅景深的拍摄效果，更加突出拍摄主体，同
时，在低照度的拍摄环境下，可以采用更低的感光度，让画面更加纯净。
镜头采用有级无级光圈切换结构，在切换到无级光圈时，在视频拍摄过程
切换光圈画面没有明显的明暗变化，光学设计优化了镜头的呼吸效应，较
低的呼吸效应，焦点切换更加自然顺畅。
镜头由9组13片镜片组成，包含1枚异常分散玻璃、1枚非球面镜片和3枚
特殊高折射玻璃的结构带来的高素质成像。外有全金属材料制成的机械
结构，保障了镜头长期使用的耐用性。

注意事项 各部件名称
长期使用保养注意事项
避免触摸镜头表面，应用专用镜头布或气吹去除镜头表面的尘埃，不使
用镜头时，应将镜头盖盖上。
使用镜头纸或镜头布清洁时,以螺旋的方式从中间向外擦拭镜头上的污
垢以及指印。
镜头从寒冷的环境突然转移至温暖的环境时，镜头的外部以及内部镜片
将会凝结水雾，所以在转移时应采取防潮保护措施。

使用说明
取下镜头后盖。將镜头卡口上的安装标记⑦对准相机座圈上的对应标
记，随后将镜头插入机身座圈，根据所购买卡口的安装方向旋转镜头，直
至咔嚓声锁紧镜头。安装时请不要用力过猛，以免导致卡口损伤。
镜头安装
关机后按住相机上的镜头释放按钮，依照所购买卡口的安装方向反向旋
转镜头，随后将镜头从座圈中拔出。
装上镜头后，请尝试旋转镜头确认是否已将其固定在相机上。
镜头拆卸
使用说明
遮光罩装卸
将遮光罩上的安装标记②对准镜头上的遮光罩安装点，然后顺时针旋转
遮光罩，直至锁紧末端为止。
如要拆卸遮光罩，按相反方向旋出即可。
安装遮光罩可减少强光并保护镜头前部元件。
安装某些滤光镜后，您可能无法再使用遮光罩。
若不使用遮光罩时，可将遮光罩反向安装于镜头上。
利用闪光灯拍摄时。遮光罩可能遮挡住光线而造成影像上的渐量现象。
所以在使用相机闪光灯或使用高度不够的外置闪光灯时,请拆卸遮光罩
后再进行拍摄。

对焦
此款镜头是全手动对焦镜头，合焦时，缓慢旋转对焦环④，直至合焦。
不要过猛过快地旋转对焦环，避免用力过度损坏对焦环部件。
镜头上的距离刻度⑤与景深刻度⑥是出于指导目的。实际焦点与景深可
能同刻度标记稍有不同。
如需要非常精确的对焦，请在固定好相机位置的情况下使用最大光圈对
焦，对焦完成后再旋至所需要的光圈值。
为了对焦的方便性，请开启相机内的峰值对焦功能(视所使用相机功能而
定)。
光圈使用
光圈在镜身上调节，采用了有级无级光圈可切换结构，根据拍摄需求选
择有级别或者无级光圈。转动镜身光圈环来选择对应的光圈，拍摄前建
议检查光圈数值，以免误触改变拍摄参数。
由于此镜头无CPU数据，无法记录光圈参数。
109

峰值对焦
1、开启机身峰值对焦选项，峰值颜色选择为红色或常用颜色，峰值选项
为 低 。
2、通过取景器或开启Live View（实时取景）功能观察画面，通过峰值来观
察对焦点。
3、转动对焦环对物体进行精确对焦。
放大对焦
先构定拍摄画面，在通过取景器或开启Live View（实时取景）功能观察画
面的同时，转动对焦环，构定拍摄画面后，通过按键或者双击屏幕将对焦
点放大，转动对焦环直至合焦。
建议：由于F0.95光圈景深很浅，拍摄的过程中建议使用脚架和设置安全
快门来保证画面稳定性。对焦建议使用峰值和放大相互结合的对焦方
式，保证焦点画面的锐利。

Thank you very much for purchasing LAOWA
FFⅡ Argus 45mm f/0.95 wide aperture lens.
This is an ultra-wide aperture f/0.95 lens for
mirrorless full-frame camera systems which
features an internal focusing design. This
lens is suitable for shooting video with a
switchable aperture ring for de-clicked
stops and minimal focus breathing.
Preface
Read this operation manual carefully to familiarize yourself with its contents and
ensure that you can operate the product properly. Keep the Instruction Manual in a
safe place where it can easily be referenced whenever required. If you are still
unable to solve the problem by reading the manual, please contact our after-sales
service for further technical support.

Features
The Argus range features an internal focusing design, which is the
mainstream photographic lens design of modern lenses. This lens
employs multiple groups of floating matching focus. It works to
correct any aberrations and to achieve corner-to-corner sharpness at
all focal distances. Laowa Argus 45mm f/0.95 CF APO with internal
focus helps the photographer with stability, preventing the dust or
ashes falling into the lens. The physical size of an internal focusing
lens does not change during focusing. It is able to use the accessories
designed to be set to a specific position like matte boxes, UV filters.
The internal focusing design achieves a low breathing effect by
inter-group interval correction, which is suitable for photo shooting
while also being more suitable for video shooting.
The lens employs a mechanism which switchable for clicked or
de-clicked aperture. De-clicked aperture allows for smooth exposure
adjustment during the video shooting. The optical design optimizes
for a lower breathing effect and it eliminates the distraction of the
changes in angle of view when moving focus from one subject to
another.
The lens is constructed of 13 elements in 9 groups, including one
aspherical element, one extra-low dispersion element and 3
high-refractive index elements. The all-metal structure ensures the
lens’ assembly accuracy and reliability.
The maximum aperture of this lens is f/0.95, which allows you to
shoot at lower light levels without boosting the ISO so the unwanted
noise in the images will be eliminated. A fast aperture also brings a
shallow depth of field for more prominent shots of the subject.

Precautions
Do not disassemble, modify the lens by yourself. Do not touch the
internal parts that become exposed as the result of external force.
Do not leave the lens where it will be exposed to high temperatures,
such as in direct sunlight and an enclosed vehicle. Excessive heat may
deform the glass elements and other parts of the lens.
Whether it is attached to the camera or not, do not leave the lens under
the sun without the lens cap attached. This is to prevent the lens from
concentrating the sun’s rays, which could cause a fire.
Do not place the sun in the frame center when shooting with backlight.
Doing so might cause a fire or harm your eyes.
The camera’s built-in flash will cause barrel shadow if used with this
lens. For best results, please use an external flash unit.
Safety Precautions Maintenance Precautions
Do not touch the surface of the lens directly. Brush off any dust with
a blower. Wipe the surface with a cleaning cloth or a lens tissue.
Try a circular motion from the center outward to remove oil,
fingerprints and grime on the lens surface.
If your lens is brought directly from a cold place to a warm place,
condensation may appear on the lens. To avoid this, be sure to take
some action to protect the lens.
Precautions

Instructions
Remove the rear lens cap. Align the mounting index⑦ on the lens
bayonet with the mounting index on the camera, and place the lens
on the camera mount, then rotate the lens according to the proper
direction of the mount type until it locks. Do not use excessive force
during installation to avoid damage to the bayonet.
After attaching the lens, please try to rotate the lens to make sure it
mounted onto the camera properly.
To attach the Lens
Turn the camera off. While pressing and holding the lens release
button on the camera, rotate the lens in the reverse direction for
attaching the lens until it stops, then detach the lens.

Align the mounting index on the lens hood② and the lens. Turn the
hood clockwise until it locks.
For detaching the lens hood, rotate it counterclockwise.
It is recommended that you use a lens hood to reduce strong light
and protect the front element.
Lens hood may be unavailable when using certain filters.
When storing, turn over the lens hood and place it onto the lens
backward.
When shooting with a flash, the lens hood may block light and
cause vignetting. So when shooting with the camera’s built-in flash
or with the external flash unit that is not high enough, please
remove the hood before shooting.

Focusing
This is a fully manual lens. Rotate the focusing ring④ slowly to get
focus.
Turn the focus ring slowly and gently to prevent the focus
mechanism from damage.
The distance scale⑤ and depth of field scale⑥ are for instructional
purposes. Actual focus and DOF may slightly differ from those scale
indications.
To get precise focus, it is recommended to focus wide open when
the camera position is fixed. Get focus first, then set the desired
aperture by turning the aperture ring.
Turn on the focus peaking on the camera to help focusing. (Note
that the function depends on camera models.)
2221

Setting the Aperture
Aperture is set through the aperture ring on the lens, and the
clicked/de-clicked aperture switch is applied. You could switch
between clicked aperture and stepless aperture depending on your
shooting. According to the shooting situation and desired depth of
field, rotate the aperture ring on the lens to the corresponding
aperture. It is recommended to check the aperture value before
shooting to avoid unintended changing the value.
Since the lens has no CPU data, the aperture value can’t be
recorded.
Method 1 Focus Peaking
①Turn on the Focus Peaking on the camera. Chose the red color or
other commonly used colors. Sets the Peaking Level to low.
②Check the frame by the viewfinder or [Live View] on the camera
and try to get focus by Focus Peaking.
③Rotate the focus ring to achieve precise focus.
Method 2 Focus Magnification
Set the frame first. Turn the focus ring while you are checking the
image through the viewfinder or [Live View] on the camera. After
setting the composition, magnify the focus by press the button on
the camera or double click the screen, then turn the focus ring to
get focus.
Note: Since the depth-of-field is very shallow at f/0.95, it is
recommended to use a tripod and set the camera to the safe shutter
speed to ensure picture stability during shooting. It is recommend-
ed to use a combination of peaking and magnification to ensure a
sharp image.
