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 hardened Alumite (Armalite) 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.

COMPACT HIGH-PERFORMANCE TELEPHOTO ZOOM
Kenko Tokina Co. Ltd, is pleased to announce the new Tokina AT-X
70-200mm F/4 PRO FX VCM-S lens featuring a new Vibration
Compensation Module and ring-shaped ultrasonic style auto-focus motor.
This lens is designed for digital cameras with full sized sensors as well as
APS-C (DX) sensors.
The Tokina AT-X 70-200mm lens is the first lens with Tokina’s new
proprietary VCM (Vibration Compensation Module). This technology allows
for up to 3 stops of vibration compensation* to reduce the affect of camera
shake in situations were a tripod or monopod cannot be used.
Additionally the new 70-200 Lens features a complete ring-shaped
ultrasonic motor for faster and quieter auto-focus. This new motor allows
for the minute adjustments between AF and manual focus modes
dramatically increasing operability. The “S” denotes the new ultrasonic motor.
The optical design of this lens has 3 SD (FK01) Super-low Dispersion glass
elements to correct for chromatic aberration and maintain heightened
optical quality throughout the zoom range.
Tokina’s announcement of the AT-X 70-200 lens expands the lens lineup
to include a compact high-performance telephoto zoom lens that has
great portability in a professional caliber telephoto lens.

TO FIT CANON • NIKON-D
FULL FRAME WIDE ZOOM
This new Tokina lens is the first in a new generation of full frame (FX) lenses
designed for professional digital SLR cameras. The 16-28 zoom range
gives the professional photographer a super-wide angle of view to get
close to subject for dramatic effect or to take in entire scenes.
NEW Silent DC Motor with GMR Senor
The 16-28 f/2.8 uses a newly developed silent DC motor that allows the lens
to focus faster and more quietly than previous generations. The DC motor
coupled with a new GMR sensor works together to increase AF speed.
Aspherical and Super-low Dispersion Glass Elements
A new, 56mm in diameter, large sizes aspherical glass element is
incorporated into the front lens group, while there are 2 more aspherical
elements in the rear group. 3 SD super-low dispersion glass elements are
also incorporated through-out the optical design to reduce chromatic
aberration, give maximum resolution, more even brightness and distortion
correction.
One-Touch Focus Clutch
Tokina’s exclusive One-touch Focus Clutch Mechanism allows the
photographer to switch between AF and MF simply by snapping the focus
ring forward for AF and back toward the camera to focus manually. There
is no need to change the AF/MF switch on Nikon camera bodies and
there is no second AF/MF switch on the lens for Canon, everything is
accomplished by the focus ring.
