precautions thoroughly. Make sure all details are observed in order to
prevent risks and injury to the user and other people.
Warning
Details pertaining to risks that may result in death or
serious injury.
●
Do not look directly at the sun or other strong light sources
through a lens. This may result in loss of sight.
●
Do not leave a lens in the sun without the lens cap attached. The
lens may concentrate entering sunlight and cause a malfunction or fire.
Caution
Details pertaining to risks that may result in injury or
damage to other objects.
●
Do not leave the product in places exposed to extremely high
or low temperatures. The product may cause burns or injury when
touched.
●
Do not insert your hand or fingers into the product. This may result
in injury.
ENG-3
General Precautions
Handling Precautions
●
Do not leave the product in excessive heat such as in a car in direct
sunlight. High temperatures can cause the product to malfunction.
●
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, first put the lens into an airtight
plastic bag before taking it from a cold to warm environment. Then take
out the lens after it has warmed gradually. Do the same when taking
the lens from a warm environment into a cold one.
●
In order to optimize aperture control, there are occasions in which the
aperture blades will move during zooming and focusing, even when the
aperture value is set for aperture-priority AE or manual exposure, etc.
●
Please also read any lens related handling precautions listed in your
camera’s instruction manual.
Shooting Precautions
●
This lens has a short focus length, which means dirt or dust on
the surface of the front lens will show up easily on photos. Use a
commercially-available blower to remove dirt or dust from the front lens
surface.
●
This lens has an extremely wide shooting angle, meaning sunlight
or other strong light sources can enter the image easily. This can
lead to flares or ghosts under certain shooting conditions. To prevent
this, we recommend being aware of where the light source is, such
as photographing from shadows or other places where a strong light
source will not enter the lens.
●
When shooting hand-held shots, be careful that your body does not
appear in the image. And when using a tripod, be careful that the leg of
the tripod does not appear in the image. Check the camera viewfinder
or monitor carefully.
●
This lens is an interchangeable lens, so the center of the circular
fisheye image circle may not always be the center of the photographed
image. In the same way, the vignetting around the four corners may not
always be even.

ENG-11
Zooming
Zoom limit/
lock switch
Zoom Limit/Lock Switch
The zoom limit/lock switch can be used to limit the zoom range.
● When using a fullframe camera, stable circular fisheye photography
is possible as the zoom range is fixed at the wide end.
After matching the zoom index with the “7”, slide the switch towards
“LIMIT” to engage the zoom lock.
●When using an APS-C camera, this limits the zoom range at the
wider side, and ensures that diagonal fisheye photography can be
done without vignetting.
After matching the C index with the “C” mark on the zoom ring, slide
the switch towards “LIMIT” to limit the zoom. When the C index is
at the “C” mark on the zoom ring, diagonal fisheye photography is
possible. At other positions, vignette-free photography is possible.
