Tokina's DX lenses are designed for use with digital
single-lens reflex (SLR) cameras having APS-C sized
sensors. Do not use Tokina DX lenses with digital SLR
cameras having and image sensor larger than APS-C
size, or with a SLR camera that uses film.
Tokina's FX lenses are designed for digital SLR cameras
with full sized (24x36mm) image sensors.
This lens is intended for use with VDSLR's. Auto focus
can be used when taking still photos but emphasis of
this lens is video use.

How to Attach/Detach the Lens

Attach/detach the lens to/from your camera according to the instructions in the manual
provided with your camera.
* When attaching/detaching the lens, be careful not to touch the electronic contacts on
the lens mounting surface nor crush these contacts by strong impact.

Focusing

The lens normally focuses automatically when the focus mode switch on the lens is set
to the Auto focus (AF) position. If the camera is in the manual-focus (MF) position, adjust
the focus by looking into the finder and turning the manual focus ring. This lens also
supports focusing through the use of a focusing aid.

Exposure Modes

For the exposure mode settings, follow the instructions in the manual provided with your
camera.

Filters

Use the appropriate sized threaded filters with these lenses. Be sure your filters are clean
before taking a photo. Perfect photographs cannot be taken if the filter is dirty or when
water droplets or other foreign particulates are on the filter. Clean the filter thoroughly
before taking photographs.
* Always use one filter at a time. If two or more filters are used together, or when a thick
filter such as a polarized filter is used, vignetting (darkening at the corners of the
exposed image) may occur.

Caution Regarding the Use of a Built-in Flash

If the camera's built-in flash is used, the light of the built-in flash will be partially obstruct-
ed by the lens, so the picture shows a large shaded area at the bottom of the image.
Therefore, it is advisable to use an external flash when this lens is attached.

Flash Photography (Red-eye Phenomenon)

When photographing people with the aid of a flash, their eyes sometimes show as red in
the image. This is called the "red-eye phenomenon. " Follow your camera manual instruc-
tions on how to remove red eye.

Lens Hood

A lens hood is designed to help reduce or prevent flare and ghost images that are caused
by strong diagonal or side rays of light striking the front of the lens. We recommend that
you use a lens hood at all times to ensure clear, problem-free photographs and video. The
lens hood also provides protection for the lens itself.
* A lens hood can be attached in the reverse direction on the front of the lens for storage.
<How to attach the lens hood>

To securely install the hood, align the mark
on the hood with the hood attachment index
( ● ) on the lens, and then turn the hood
clockwise, as viewed from the front, until a click
is heard. Then, confirm the position of the mark

One-Touch Focus Clutch Mechanism

<How to switch from the Auto focus position to manual focus position>
The lens focus mode can be switched between the auto
focus (AF) mark on the lens barrel and manual focus (MF)
positions at any time by moving the manual focus ring
forward or backward. When the focus ring is moved back
toward the mount the AF mark will be covered and the lens
will only focus manually. Move the focus ring toward the front of the lens for auto-focus.
* For lenses using either the Nikon or Canon mounting system, it is possible to use
manual focus without switching the focus mode switch on either the camera body or
Hood attachment index
the lens to the manual position.
In the Auto focus position the manual focus ring turns freely.
* For all Canon mounts and Nikon mount, the built-in AF motor will be automatically
turned off when the focus ring is switched to MF mode position.
* When the Canon mount is switched to the MF position, the motor switch in the lens
automatically turns off. (The motor switch in the lens automatically turns off when
Nikon mounts are switched to the MF position as well. )
* Depending on the lens model, you may hear a sound from inside the lens when the
▼mark
lens is shaken lightly. This is the sound of the ball bearings that are designed to
smooth the action of the focus ring. It does not indicate a problem with the general
functioning of the lens.

About AT-X 107 DX Canon Mount

Manually turning the focus ring with the Focus Mode Switch near the lens mount in AF
position (Photo ①) can place stress on the internal lens gears and result in damage.
To take photos using manual focus, make sure you set the Focus Mode Switch to the (M)
position (Photo ②). Return the Focus Mode Switch to the AF position (Photo ①) when
you want to resume taking photos in auto focus.

■ Precautions for Use

● Attaching a lens hood
Unlike a SLR camera using a silver halide film, a digital SLR camera produces a
large measure of reflection due to its imaging sensor. It is therefore recommend-
ed that a lens hood be attached when you're taking photographs with a digital
SLR camera. Especially when a wide-angle lens is used, a lens hood should be
attached even indoors.
● The DX lens is designed exclusively for a digital SLR camera of APS-C size.
Tokina's DX lenses are deigned exclusively for use with digital SLR cameras
having an APS-C sized image sensor. Using the DX lenses with a digital SLR
camera with an imaging sensor of a size larger than APS-C, or with a SLR camera
designed for silver-halide film, will cause vignetting.
● Using Ultra-Wide Angle Lenses.
If you are using a super/Ultra-wide angle lens in auto focus, it may not focus on
the periphery (outer edges) of the frame in AF mode.
Since the depth of field is an ultra-wide angle zoom lens is very deep, focus
detection in the periphery of the frame becomes difficult for cameras set in
multi-point auto focus.
We recommend using a central focus detection setting on your camera when
using auto focus with ultra-wide angle lenses.
