Tokina opera 16-28mm f/2.8 FF Lens for Canon EF
The Canon EF-mount Tokina opera 16-28mm f/2.8 FF is a flexible wide-angle zoom well-suited to landscape, architectural, and astrophotography applications. The f/2.8 constant maximum aperture pairs with the broad field of view range to realize an ideal lens for working in available light conditions and for using shallow depth of field techniques. The optical design incorporates aspherical and low-dispersion glass elements, which help to control distortion and color fringing throughout the zoom range in order to produce sharp, clear, and color-accurate imagery. A multi-coating has also been applied to individual elements in order to suppress flare and ghosting for improved contrast when working in bright and backlit conditions. Complementing the optical design is a sophisticated focusing system, which uses a DC motor, Silent Drive module, GMR magnetic sensor, and an internal focusing design in order to provide especially quiet and quick focusing performance to suit stills and video needs.
A One-Touch Focus Clutch Mechanism also allows for fast switching between autofocus and manual focus settings. Additionally, this 16-28mm f/2.8 sports a nine-blade diaphragm to produce a pleasing bokeh quality and it has a built-in lens hood to shield the bulbous front element from stray light. A DC motor, along with a Silent Drive module, GMR magnetic AF sensor, and internal focusing design, affords especially quiet, precise, and fast autofocus performance. Additionally, a One-Touch Focus Clutch Mechanism permits switching between AF and MF modes by simply snapping the focus ring back and forth.
The optical design performs just optimal resolution at the aperture wide open that greatly increases by stepping down to f/4 and narrower. To make the lens suitable for landscape shooting and BW photography, engineers made maximum efforts to realize the high level of contrast and rich color gradation in the image
Nine-blade diaphragm promotes a pleasing out-of-focus quality that benefits the use of shallow depth-of-field techniques
Multi-coating has been applied to individual elements to suppress flare and ghosting in order to achieve greater contrast and color fidelity when working in strong lighting conditions
