Tokina Opera 16-28mm F/2.8 FX Zoom Lens for Canon EF #OPR-AF168FXC

About opera Series
With the debut of 50mm F1.4 FF Tokina is launching a new series of next generation, premium full-frame lenses for high-end DSLR cameras called "opera" series. The new series is designed to perfectly match recent high-resolution full-frame DSLR cameras that demand the highest quality optical designs. Building on the award winning heritage of Tokina's AT-X line of lenses, the new opera series will offer an ever-expanding, premium line of Full-frame lenses that meet the growing demands of high-performance DSLR cameras.

In modern society the word "opera" is commonly used to indicate stage art works that combine drama, music and dance. In Italian it means work or work of art. As an omitted art genre definition opera comes from "opera musicale" that means a piece of music work. In Latin opera comes from "opus" that is still used in contemporary language meaning "great literary, artistic or intellectual work" (e.g. "magnum opus", "opera magna"). We chose the name opera for our new premium full-frame DSLR lens series with the idea that it will help the photographer in creating real "works of art".

About the Product
The Tokina opera 16-28mm F2.8 FF is the perfect super-wide angle zoom lens for photographers who specialize in landscape, architecture, documentary, environmental portraits, and night sky image captures. With a constant F2.8 aperture throughout the entire zoom range, the lens provides excellent sharpness and improved contrast suitable to today's high-resolution cameras. The lens uses an improved auto-focus system for fast and accurate AF. It maintains the exclusive one-touch focus clutch mechanism for easy switching between AF to MF.

Advanced AF and One-touch Focus Clutch
The new 16-28mm F2.8 FF is designed for a great user experience and to give photographers the confidence to create beautiful images. The lens includes a newly designed Silent Drive module using new GMR magnetic auto-focus (AF) sensors for faster, smoother, and quieter AF than the previous generation. Additionally, the directional rotation of the focus ring matches the direction of proprietary Nikon and Canon lenses.

The One-Touch Focus Clutch Mechanism makes switching from AF to manual focus (MF) simple. While in AF mode the user only needs to snap the focus ring back toward the camera to engage "real" manual focus control. This gives the photographers an authentic tactile MF feel with hard stops on either side of the focus range like traditional manual lenses.

Advanced Optical Design
The lens incorporates a complex optical design, with 15 elements in 13 groups. Using 3 aspherical lenses including a large aspherical P-MO element and 3 all-glass molded Low-Dispersion (SD) elements, the lens effectively suppresses chromatic and spherical aberrations. The large front element provides super-low distortion and low light fall-off for straight lines and minimal exposure vignetting. Perfect for architectural, landscape, and astro photographers.
