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-the-
art 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.
