Visionary technology
makes a difference you can see.
Tokina’s proprietary AT-X technology has been evolving
toward optical perfection for more than 30 years.
Since our mission began in 1981 we have made continuous
advances. Each new model is a further refinement in a continuing legacy
of excellence in design and materials. The current AT-X PRO series
continues this evolution of excellence by using the most state-of-theart technology anywhere.
More Quality Than Meets The Eye.
The Tokina difference comes from special material selection and assembly
technology that employs micron-unit quality control. This ensures
optimum consistency while maintaining the highest quality for every
lens. Worldwide, both professionals and knowledgeable photography
enthusiasts rely on Tokina lenses.
AT-X Technology
AT-X comes from our original concept of “Advanced Technology Extra.”
This vision encompasses a special group of lenses that are manufactured
without compromise, using the most advanced design and fabrication
technologies available. The use of unique and unprecedented optical systems
independently pioneered by Tokina, has made advanced features, high
performance, lightweight, and compact designs a reality. Of course, we have
also given full attention to ergonomics and handling. To any user, AT-X means
excellent performance through superior technology.
Mechanisms
1. All metallic moving parts are coated with a special lubricant to
improve durability.
2. Tokina’s independently developed technology maintains the high
precision of mechanical fittings, accurately measured in microns.
3. Micron tolerances also give smooth operation and durability to
operating rollers and internal focus cams.
4. Brass is used in the lens mount to maintain high precision. Other
mechanisms are plated with hard chrome for optimum durability.
Exterior Finish
1. PRO models have a Anodized Aluminum finish to increase
durability and give a top-quality feel and finish.
2. Ergonomic designs emphasize control, grip and ease of operation
with textured rubber used on zoom and focus barrels. These are
original Tokina materials, designed to give many years of faithful
service without deterioration.
Operation
1. Use of our special alloy Duralumin for metal parts provides excellent
durability, stabilizes torque and provides better handling. It also
maintains smoother operation under all conditions.
2. Our special lubricant is used on moving parts, formulated to perform
even under extremes of temperature.
Lens Coatings
Resistance to flare and ghosting, plus faithful color reproduction are all
achieved by a unique coating technique – yet another reason for Tokina’s
reputation for incredibly sharp and clean images.

Angle of View
The range across the film surface onto which the subject is exposed is
expressed as an angle, called the angle of view. Wide-angle lenses with their
short focal lengths have a wide angle of view, which means the exposure
range is wide. Conversely, telephoto lenses, which have long focal lengths,
have a narrow angle of view, making the exposure range narrow. So a
wide-angle lens is used to take a wide area of a subject nearby whereas a
telephoto lens is used to take only part of a subject located further away.
A single zoom lens, meanwhile, can function as a number of lenses with
different focal lengths, enabling you to smoothly alter the angle of view and
quickly frame the shot. You can select your lens to create the effect of distance
or depth of field, or to suit the location and surrounding conditions.

Depth of Field
Perspective
When you focus on a subject, there is part of the subject that is in focus and
parts in front and behind which are not in focus. This range in which the object
is seen to be sharply in focus is called the depth of field.
Perspective is the visual effect of moving a subject which is in the foreground
closer to or further from the background. If you take photographs with lenses
of different focal length while keeping the size of the subject in the foreground
constant, the background appears to be further away and the sense of
perspective is exaggerated with a short focal length wide angle lens.
If the focal length is kept the same, the depth of field gets deeper (the range
in which the subject is sharp gets wider) as the aperture is stopped down, and
it gets shallower (the range in which the subject is sharp gets narrower)
as the aperture is opened.
Even when the aperture stop is the same, the depth of field gets shallower as
the subject distance gets shorter, and deeper as the subject gets further away.
Furthermore the depth of field is deeper with a short focal length wide angle
lens, and shallower with a long focal length telephoto lens.
With a long focal length telephoto lens, the background appears to be closer
to the subject and the sense of perspective is lessened. You can greatly
change the feeling of presence even with the same subject by using this sense
of perspective.

One-Touch Focus Clutch Mechanism
The newly improved one-touch focus clutch allows the focus to be moved
quickly and easily from the AF position back into the MF position. In Nikon
and Canon mounts, the lens can be set for manual focusing without an
AF/MF switch or setting the body to the AF position.
Auto Focus
Aspherical Optics
Standard lenses are made from a combination of spherical lens elements.
However, there can be problems with such lenses when light entering at the
edges of the lens may not be perfectly focused at the same point as light
entering at the center. That presents limits to performance in wide aperture
and super wide-angle lenses.Tokina uses aspherical glass elements in many
of its lenses. In addition to correcting spherical aberration, these lenses fully
correct light quantity and distortion at the edge of the image and provide
excellent results when used in combination with floating elements. Through
technical cooperation with Hoya, Tokina has succeeded in producing high quality
molded glass elements with a greater aspherical shape than any other lens so far.
This technique is unparalleled in its technological sophistication and excellence.
Manual Focus
Internal Focus System
The two main methods of lens focusing are either the complete straight forward
movement of elements (used mainly with single focal length lenses), or the
rotation of the entire front lens barrel group (used mainly with zoom lenses).
The internal focusing system used by Tokina moves each lens group, but does
not change the overall length of the lens - this is especially useful with
telephoto designs.
The internal focusing system has a number of advantages, including:
1. Faster focusing
2. Improved handling due to fewer movements near the center of gravity
3. More compact lens designs
4. Superior use of filters as the front filter thread does not rotate
30
SD (Super Low Dispersion) Glass
Lenses with the SD mark use Super-low Dispersion glass which minimizes the
secondary spectrum caused by chromatic aberration. Basically, these lenses
use FK01 and FK02 optical materials which gives them SD (APO) qualities.
This provides excellent image quality in telephoto lenses of 200mm or more
by correcting color aberration across the entire picture and bringing all colors
into focus accurately at the film plane.
