LAOWA FF 100mm F2.8
CA-Dreamer Macro 2X

Thank you for purchasing LAOWA老
蛙FF 100mm F2.8 CA-Dreamer Macro 2X.
Featuring max. 2X magnification and APO
technology, the lens is dedicated to Full
Frame system cameras. It is designed to
deliver stunning image quality ranging from
macro to infinity, which greatly supports you
to capture tiny subjects such as small insects
and jewelries etc.
Prior to use, please read this instruction manual carefully to ensure
proper use. Keep the Instruction Manual in hand and refer to it whenever
needed. If you are still unable to solve the problem by reading the
manual, please contact our after-sales service for further technical
support.
Introduction

PERCAUTIONSFEATURES
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 a 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 rays, which could cause a fire.
Do not place the sun in the frame center when shooting with
backlight. Sunlight focused into the camera when the sun is in or
close to the frame could cause a fire or damage to your eyes.
The lens itself may block the light and cause light fall-off when
using the camera’s built-in flash, so external flash will be
recommended here.
Designed for Full Frame cameras, the lens’ angle of view will be
narrowed when mounted on APS-C format ones.
Safety Precautions
The Canon and Sony versions of the lens feature 13-blade circular
aperture, which contributes to producing soft round-shaped
bokeh by blurring the point light source.
*Nikon & Pentax versions featuring 7-blade aperture
The lens is comprised of 12 elements in 10 groups with 2 pieces of
ED glass included, which contribute to creating outstanding
imaging. All-metal construction also ensures long-time
durability.
Since canon versions are equipped with auto aperture and
internal electric motor, aperture can be set on the camera with
lens data being recorded. It effectively enables photographers to
get focus wide open when shooting macro.
Unlike common macro lenses, LAOWA老蛙 FF 100mm F2.8
CA-Dreamer Macro 2X offers superior performance that can focus
from infinity to 2X, with superb chromatic aberration correction
resulted from its APO technology. High magnification helps
generate more creative works.

Maintenance Precautions
PERCAUTIONS
Avoid touching the lens surface. Remove the dust on the lens surface
with a lens cloth or a blower. Keep the lens cap attached.
Using a circular motion with a lens tissue or cleaning cloth, gently
remove oil, fingerprints, and grime from the lens surface, working
from the center outward.
If the lens is taken from a cold environment into a warm one,
condensation may develop on the lens surface and internal parts. To
prevent condensation in this case, please take measures to protect
against moisture before moving the lens.

INSTRUCTIONS INSTRUCTIONS
Mounting the Lens Attaching and Removing the Lens Hood
Remove the lens rear cap. Align the Lens mounting index (8) with
the mark on the camera mount, then insert the lens into the camera
mount and turn the lens in the direction for your lens version until it
clicks into position.
Line up the Lens hood mounting index with the mounting dot on
the lens, and turn the lens hood clockwise until it clicks.
Turn the lens hood in the direction opposite to that for attaching to remove it.
The lens hood helps reduce lens flare and protects the lens front
element from damage.
Lens hood may be unavailable when using some certain filters.
Place the lens hood backwards over the lens when not using it.
When shooting with a flash, the lens hood may block light which
may cause vignetting. So when shooting with camera’s built-in
flash or with the external flash unit that is not high enough, please
remove the hood first before shooting. Selecting dedicated macro
ring flash is also a great option.
As the lens is a manual focus lens, please slowly turn the Focus ring
(3) to get focus.
Gently turn the focus ring to prevent the focus mechanism from damage.
The Distance scale(4) & Depth-of-field scale(5) are simply for
instructional purpose. Actual focus and DOF may slightly differ from
those scale indications.
To get precise focus, make sure camera position is fixed, focus on
the subjects wide open. Get focus first and then set the desired
aperture by turning the aperture ring.
Use [Focus Peaking] makes it easier to get focus. ( Note that the
function depends on camera models.)
Gently rotate the lens to make sure it is properly attached to the
camera.
Aperture can be set on the camera with lens data being recorded in that
canon versions of the lens feature electronic chips. As for other
mounts, please set [Release shutter w/o lens] to [enable] on the camera
because Non-CPU lenses cannot provide actual EXIF data.
Focusing
Detaching the Lens
Turn the camera off. Press the lens release button. Turn the lens in
the direction opposite to that for attaching and pull it out.

INSTRUCTIONS
Setting the Aperture(unavailable to Canon version)
Turn the Aperture ring(6) on the lens to choose the corresponding
aperture according to the shooing situation and desired depth-of-field.
The lens cannot provide actual aperture value of the lens to the
camera since it is a manual focus lens.
Aperture-priority is a better option than Shutter-priority for the lens
because of its manual aperture. ( Note that metering precision
depends on the camera models. )
* Canon version lenses allow you to set the desired aperture on the
cameras.
The lens features 2X magnification, 24.7cm min. focusing distance
and 13cm min. working distance.
INSTRUCTIONS
Macro Shooing
For the Nikon version lenses, select [ Non-CPU Lens Data ], set the widest
aperture and focal length, and preset the aperture you desire on
the lens to obtain precise auto exposure.
For high magnification close-ups, please be careful not to touch the subjects
in that the lens’ working distance is extremely short.
Magnification is the relationship between of the size of subject's projection
on the image sensor and that of the subject in reality.
Focusing Tips
Method 1 Magnification Priority
Set the magnification first, and then turn the focus ring to the
desired magnification marked on the lens.
Look through the viewfinder or enable [Live View], and roughly
focus to obtain proper focus by moving the camera back and forth.
Turn the focus ring to achieve precise focus.
Method 2 Framing Priority
Frame first. Turn the focus ring while you are looking through
viewfinder or enable [ Live View], and then follow the step 2, 3 as the
method 1 above.
