Instruction Manual

Thank you for purchasing SAMYANG lens.
We believe that this new 7.5 mm 1:3.5 UMC FISH-EYE MFT lens will
provide a special photographic experience.

The 7.5 mm 1:3.5 UMC FISH-EYE MFT lens has a compact size and
provides easy portability owing to an optical design optimized for Micro
Four-Thirds cameras, and is able to implement special images when taking
photos of a subject that is close as well as far away.

Features of 7.5 mm 1:3.5 UMC FISH-EYE MFT

1. Optical design for the image size for digital MFT only (1:2x)

2. Corrects aberrations using three Extra-low Dispersion lens and one
complex aspherical lens and, at a fully opened position, produces high
resolution and high contrast at the center of the lens as well as around
the periphery of the lens.

3. Flower-shaped lens hood and multi-coating suppress flaring and
ghosting.

The 7.5 mm 1:3.5 UMC FISH-EYE MFT lens for photography is designed
with its own mount. You can easily take photos without installing an
additional adapter, mounting the lens directly onto the camera.
Read this instruction manual carefully and use it properly.
※ Please read the ‘Safety Precautions’ at the back of this instruction
manual prior to use.

The 7.5 mm 1:3.5 UMC FISH-EYE MFT lens mount is uniquely designed for
Olympus (MFT) and Panasonic (MFT).

[Attaching]

Hold the hood locking area of the lens gently, align the depth of field scale of the
lens with the lens attachment reference point on the camera, push the lens into the
camera and turn the lens gently until it makes a clicking sound and the distance
scale is positioned at the upper part of the camera.

[Detaching]

Hold the hood locking area of the lens gently, press the lens release button on the
camera, turn the lens in the opposite direction of the attaching direction to detach
the lens.

3. Focus Adjustment

Y ou can set the focus for a subject by turning the focus adjustment ring when
using the 7.5 mm 1:3.5 UMC FISH-EYE MFT lens,
as it is a Manual Focus (MF) adjustment lens.

[Olympus (MFT), Panasonic (MFT) Mount]

① To change the focus from a subject that is far away to a subject that is close

Turn the focusing ring to the left (from ∞ to 0.09) and focus on the clearest

subject using the indication signal in the camera, or by checking the LCD.

② To change the focus from a subject that is close to a subject that is far away

Turn the focusing ring to the left (from 0.09 to ∞) and focus on the clearest

subject using the indication signal in the camera, or by checking the LCD.

The aperture of the 7.5 mm 1:3.5 UMC FISH-EYE MFT lens is not geared to the
camera.
If the brightness (F-number) is set to 8 or larger, you may not be able to focus the
subject properly because it is difficult to see the subject through your camera
viewfinder. Therefore, when this lens is attached to your camera, turn the aperture
adjustment ring to fully open the aperture and check that the focus is correct; then
readjust the aperture to set the depth of field and brightness you want. Then take
your photograph.

1) Set the camera mode dial to 'M'.

2) Adjust the shutter speed by turning the dial to achieve the appropriate exposure
for the brightness.

The shutter speed of some Olympus (MFT) and Panasonic (MFT) cameras
changes automatically if the shooting mode dial is set to A and the brightness is set
by turning the aperture adjustment ring. Therefore the shutter speed is not required
to be set additionally as with the M mode.
