Tokina AT-X 107 DX AF 10-17 mm f/ 3.5-4.5 Fish-Eye Lens パンフレット

●

 Limiting the Focus Distance Range

This lens is equipped with a focus-limiting switch, which makes it ideal for use 
as a moderate telephoto or portrait lens. Lock the lens out of the macro range 
to shorten the focusing time by setting this switch to the LIMIT position instead 
of the FULL position.

FULL: The lens will focus from 0.3m to infinity.

LIMIT: The lens will focus from 

approximately 0.38m to 
infinity OR from approxi-
mately 0.3m to 0.36m in 
the macro range. 

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. 

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.

* Depending on the lens model, you may hear a sound from inside the lens 

when the 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 prob-
lem with the general functioning of the lens.

■ 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 recommended 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 camer-
as 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. 

※ The         Mark (certification mark for conformance with the European export inspection requirements) is shown on lenses containing electronic parts.

The specification data is based on the use of the lens with a Nikon camera.

●

 Note on Macro Photography

In macro photography, the subject and lens become very close and the magnifi-
cation increases as a result. Therefore, even a slight vibration or movement of 
the camera can affect image quality. In macro photography, hold the camera 
securely to eliminate vibrations. For vibration-free photographs Tokina highly 
recommends the use of a tripod, cable release and/or a wireless remote control 
and an external flash.

The F-value shown on the lens indicates the brightness of a subject located at 
infinity. The Maximum aperture of a lens is always measured with the focus at 
infinity.  If the macro magnification is raised, the brightness of the subject will 
decrease. This reduced brightness is called the “effective F-value,” while the 
exposure correction corresponding to the decrease in subject brightness is 
called “exposure magnification.”

 
* If you are doing macro photography using a Nikon mount, the display on the 

camera body will indicate a change in aperture as the focus distance 
approaches the minimum value, even when the lens’s F-value is set to F2.8 
(fully open), until the effective F-value finally reaches F5.6.

●

 Aperture Ring

Lock the aperture at the minimum (Highest F number), otherwise, the shutter 
will not release. 

●

 Exposure Correction

 

When the macro magnification is increased, the brightness at the film plane will 
decrease. On a TTL auto-focus camera or when shooting with a TTL flash, the 
quantity of light passing through the lens is measured and the exposure is 
corrected automatically.

 
If the exposure is measured using an external light meter or when a non-dedi-
cated external flash is used, the exposure must be corrected by a corresponding 
increase (in exposure magnification) equal to the decrease in brightness from 
the change in macro magnification.
The table shown at right lists the exposure magnifications for the different 
macro magnifications applicable to the 100mm F2.8 Macro D lens.

The table shown at right lists the 
exposure magnifications and aperture 
openings at different macro magnifica-
tions of 1:10 and above. If you don’t 
want to change the aperture setting, 
correct the exposure by changing the 
shutter speed.

How to Attach/Detach the Lens

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.

Focusing

If the camera’s built-in flash is used, the light of the built-in flash will be partially 
obstructed 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.

Caution Regarding the Use of a Built-in Flash

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 instructions on how to remove red eye.

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

Exposure Modes

Lens Hood

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 the lens to the manual position.

 

In the Auto focus position the manual focus ring turns freely.

 
* For all Canon mounts and, 11~20mm F2.8 DX / 12~24mm F4 DX II / 11~16mm 

F2.8 DX II / 12~28mm F4 DX Nikon mount, the built-in AF motor will be 
automatically turned off when the focus ring is switched to MF mode position.

One-Touch Focus Clutch Mechanism

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 to protect the lens.
* The 11~20mm F2.8 DX / 12~24mm F4 DX II/100mmF2.8 Macro D/11~16mm 

F2.8 DX/11~16mm F2.8 DX II/12~28mm F4 DX lens hood can be attached in the 
reverse direction on the front of the lens for storage.

 Macro Magnification

“Macro magnification” refers to the ratio of the 
image captured on film or the sensor to the actual 
subject size. For example, if a subject 3cm in size is 
captured as a 1cm image on film, the magnifica-
tion is “1:3.” The macro magnification is indicated 
above the focus distance. In the example shown 
at right, the focus distance is 0.32m, while the 
macro magnification is approximately 1:1.3.

To securely install the hood, align the mark 
on the hood with the hood attachment 
indicator (●) on the lens, and then turn the 

hood clockwise, as viewed from the front, 
until a click is heard.
Important-Confirm that the 

▼ mark on the 

hood is aligned with the center index on 
the lens.

 

Place the lens hood on the lens by aligning 
the index (     ) on the hood with the hood 
attachment index dot (●) on the lens. 

Secure the hood by turning it clockwise 
(when viewed from the front) until it clicks 
into place. Grabbing the tip of the lens 
hood with a strong force will make it 
difficult to attach/detach the hood. When 
attaching/detaching the lens hood, do so 
by holding the base of the hood (the part 
attached to the lens).
