Tokina

The opera 50mm f/1.4 FF is a fast normal-length prime lens for Canon EF-mount DSLRs. Its especially bright f/1.4 maximum aperture offers improved control over depth of field for working with selective focus techniques and also benefits shooting in difficult lighting conditions. This lens sports a refined optical design, which includes both low dispersion and aspherical elements, to match contemporary high-resolution sensors in order to realize a high degree of sharpness and clarity. An ELR Coating is also featured to control surface and internal reflections in order to greatly reduce flare and ghosting. Suiting a multimedia method of working, a ring-shaped ultrasonic motor has been used to provide fast, near-silent autofocus performance that is ideal for photograph and video applications alike. Additionally, this 50mm f/1.4 also sports a weather-sealed construction for working in inclement weather conditions. Notably, bright f/1.4 maximum aperture benefits working in low-light conditions and also affords increased control over depth of field for isolating subject matter and working with selective focus techniques. One aspherical element is located in the rear group and helps to control spherical aberrations and distortion in order to gain improved sharpness and more accurate rendering. The ring-shaped ultrasonic motor delivers quick, quiet autofocus performance, as well as full-time manual focus override, that suits both stills and video applications.

The Nikon F-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 the 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 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. Constant f/2.8 maximum aperture offers consistent performance and excellent light transmission throughout the zoom range. Three glass-molded low dispersion elements greatly reduce color fringing and chromatic aberrations in order to produce greater clarity and color accuracy. 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. A built-in petal-shaped lens hood helps to prevent stray light from causing flare and also offers some protection to the front lens element.
