[100mm F2.8 Macro D]

● 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 (certication mark for conformance with the European export inspection requirements) is shown on lenses containing electronic parts.

The specication 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.

<Eective F-Value and Exposure Magnication>

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.

Tokina's DX lenses are designed for use with digital

single-lens reflex (SLR) cameras having APS-C sized

sensors. Do not use DX lenses with digital SLR cameras

having an imaging sensor of a size larger than APS-C,

nor with a SLR camera designed for silver-halide film.

The Tokina D lens can be used with both digital SLR

cameras with APS-C size sensors, digital SLRs with full

frame sensors and SLR film cameras.

Descriptions of Parts 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.

Filters

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.

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.

[100mm F2.8 Macro D]

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).
