Tokina ATX-i 11-20mm f/2.8 CF Lens for Nikon F
The Nikon F-mount Tokina atx-i 11-20mm f/2.8 CF is an ultra-wide zoom that is ideal for landscape, architecture, interior, and astrophotography applications. Its bright f/2.8 constant maximum aperture affords consistent brightness throughout the zoom range and benefits working in available lighting conditions. The optical design incorporates a series of aspherical and low-dispersion elements, which suppress a variety of aberrations for improved sharpness and clarity. Individual elements are also multi-coated to resist flare and ghosting for greater contrast and color accuracy when working in bright or backlit conditions. Complementing the optics, this lens features a One-Touch Focus Clutch Mechanism for fast changing between AF and MF settings, and an internal focusing design is used for responsive focusing performance.
A constant maximum aperture of f/2.8 throughout the entire zoom range is realized to achieve great results in low light conditions, for depth of field control and easy manual shooting, while maintaining a reasonable size and weight. To achieve the exceptional optical performance required for an ultra-wide-angle zoom lens 3 aspherical glass elements and 3 Super-Low Dispersion glass elements were used in order to minimize distortion, and manage spherical aberration and astigmatism while achieving excellent edge-to-edge resolution and high contrast through the entire image.
The lens provides a wide cinematic feel, minimized breathing, and no edge distortion while panning, and the overall weight and internal focus design make it an ideal choice for gimbal work
The constant f/2.8 aperture lens provides excellent edge-to-edge sharpness and resolution. Reduces flare and ghosting, while maintaining excellent contrast and color
