Thank you for purchasing a Sigma lens. Please read
this instruction manual carefully to correctly under
-
stand the lens’s functions, operation, and handling
precautions, and enjoy taking photographs.
WARNING!! : SAFETY PRECAUTIONS
– Do not look directly at the sun, through the lens.
Doing so can cause damage to the eye or loss of
eyesight.
– Do not leave the lens in direct sunlight with
-
out the lens cap attached, whether the lens is
attached to the camera or not. This will prevent
the lens from concentrating the sun’s rays, which
may cause a fire.
– The shape of the mount and its surrounding
parts are very complex. Please be careful when
handling them so as not to cause injury.
– Please select a sturdy tripod that is capable of
supporting this lens. If the tripod is not sturdy
enough, it may cause the lens to fall.
– This lens has a built-in magnet. Please keep it
at least 5 cm (2 in) away from medical devices
such as cardiac pacemakers as it may adversely
affect them.
– Please do not place credit cards featuring a mag
-
netic strip (or any other object that is sensitive
to a magnetic field) close to the lens as it could
damage the data stored on the card.

DC LENS
This lens is designed for mirrorless cameras
equipped with an APS-C size image sensor. It can
also be used on full-frame mirrorless cameras, but
please note that the lens’s image circle will not
cover the entire sensor so the camera may need to
be switched into crop mode. For more information
on attaching an APS-C size lens to a full-frame
mirrorless camera, please refer to the instruction
manual of the camera you are using.
IRIS RING CLICK SWITCH
(L-Mount / Sony E-mount / FUJIFILM X Mount)
It is possible to select to activate/deactivate the
click of the iris ring, and this function would be
effective for movie shooting. To deactivate the click
of the iris ring, set the switch to “OFF” (Fig.4).
IRIS RING LOCK SWITCH
(L-Mount / Sony E-mount / FUJIFILM X Mount)
If you use the Iris Ring Lock Switch when the aper
-
ture is set to A, it will be fixed on A. This function
will be useful when adjusting the F-stop via the
camera (Fig.5).
If you use the Iris Ring Lock Switch when the aper
-
ture is on any aperture setting other than A, the
aperture ring can still be rotated from maximum
to minimum aperture. This function will be useful
when adjusting the F-stop via the Iris ring (Fig.6).
CONTROL RING (Fig.1-10)
(Canon RF Mount)
The function assigned to the Control Ring function
is set in the camera menu. For instructions on how
to do this refer to your camera's manual.
LENS HOOD
The lens hood helps to prevent flare and ghosted
images caused by bright illumination from outside
the picture area. Attach the hood and turn clock
-
wise until it stops rotation (Fig.7). To detach the
hood, turn counter-clockwise while pushing the
button (a) until it stops rotating (Fig.8).
– When not in use, the lens hood can be attached
upside-down (Fig.9).
BASIC CARE AND STORAGE
– Avoid any shocks or exposure to extreme high or
low temperatures or to humidity.
– For extended storage, choose a cool and dry
place, preferably with good ventilation. To avoid
damage to the lens coating, keep away from
mothballs or naphthalene gas.
– Do not use thinner, benzine or other organic
cleaning agents to remove dirt or finger prints
from the lens elements. Clean by using a soft,
moistened lens cloth or lens tissue.
– The lens has a dust and splash resistant struc
-
ture. Although this construction allows the
lens to be used in light rain, it is not the same
as being waterproof, so please prevent large
amounts of water from splashing on the lens. It
is often impractical to repair the internal mech
-
anism, lens elements and electric components if
they are damaged by water.
– Sudden temperature changes may cause
condensation or fog to appear on the surface
of the lens. When entering a warm room from
the cold outdoors, it is advisable to keep the
lens in the case until the temperature of the lens
approaches room temperature.
– In case the camera does not incorporate the lens
compensation function, the lens cannot offer
distortion compensation.
ATTACHING TO THE CAMERA BODY
Please refer to the camera’s instruction manual for
details on how to attach it to or detach it from the
camera body.
– On the lens mount surface, there are electrical
contacts. Please be careful with their handling
as scratches or dirt on them could cause mal
-
functions or damage.
FOCUSING
(L-Mount / Sony E-mount / Canon RF Mount)
For autofocus operation, set the focus mode switch
on the lens to the “AF” position (Fig.2). If you wish
to focus manually, set the focus mode switch on
the lens to the “MF” position. You can adjust the
focus by turning the focus ring (Fig.1-2).
– Please refer to camera’s instruction manual for
details on changing the camera’s focusing mode.

work.
– Some camera bodies can customize the function
of the AFL button, so please check the details of
the camera’s instruction manual.
SETTINGS THE AF FUNCTION BUTTON

(Fig.1-3) (Fig.3).
