The Tokina ATX-I 11-16MM f/2.8 CF Canon EOS wide-angle zoom opens up a whole new world of imaging possibilities. Constant f/2.8 aperture provides excellent edge-to-edge sharpness and resolution. This lens is designed for use with APS-C DSLRs, offering an effective focal length range of approximately 16-24mm full-frame equivalent - and it hits all the marks for photographers and videographers who want to take advantage of exciting wide-angle visual potential.
The re-designed lens is constructed of 13 elements in 11 groups, including two aspherical elements, a 'large' aspherical P-MO element and two all-glass moulded low dispersion (SD) elements that work together to try to eliminate chromatic and spherical aberration. Minimized distortion and excellent edge-to-edge resolution and contrast with minimal light fall-off are other video-friendly optical characteristics of this lens.
True to traditions, Tokina incorporated a lot of metal parts inside the lens for a reassuring built quality and long time utilization in different shooting conditions. The sophisticated exterior design is specifically developed to match the design of contemporary DSLR cameras. Precise attention was also paid to zoom and focus ring rotation amount with no play and tight dampening. The overall length of the Tokina atx-i 11-16mm f/2.8 CF does not change when focusing and zooming thanks to internal focus construction.
The focus mechanism has also been updated to a One-Touch Focus Clutch Mechanism that allows you to get a “real” manual focus feel by “snapping” the focus ring back toward the camera. Once in MF mode, users are promised: “an authentic tactile MF feel with hard stops on either side of the focus range like traditional manual lenses.” As an added bonus, the directionality of the focus ring will match your other Canon and Nikon lenses.
Other features include a nine-blade aperture diaphragm, a 77mm front filter thread and a minimum focusing distance of 30cm.
The new Tokina atx-i 11-16mm f/2.8 CF incorporates a complex optical design, with 13 elements in 11 groups. Using 2 aspherical lenses including a large aspherical P-MO element and 2 all-glass moulded Low-Dispersion (SD) elements, the lens effectively suppresses chromatic and spherical aberrations. The front element provides a super-low distortion and low light fall-off for straight lines and minimal exposure vignetting. Perfect for architectural, landscape, astrophotographers, and cinematographers.
Anti-reflective multi-layer coating improves light transmission and minimizes reflections while water-repellent coating makes wiping and cleaning the surface of the front glass element easier.
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 photographers an authentic tactile MF feel with hard stops on either side of the focus range like traditional manual lenses. Additionally, the directional rotation of the focus ring matches the direction of proprietary Nikon and Canon lenses.
Popular among cinematographers too, because the lens provides a wide cinematic feel, minimized breathing, no edge distortion while panning, and the overall weight and internal focus design make it an ideal choice for gimbal work.
Precise attention was paid to ensure the zoom and focus ring rotation had the optimal rotation with no play and a smooth dampened feel. The focus ring will match the rotation of native mount lenses.
