Product Description
The Tokina atx-i 11-16mm f/2.8 cropped frame (CF) is an ultra wide angle zoom
lens for APS-C sensor DLSR cameras.
A constant maximum aperture of f/2.8 throughout the entire zoom range helps
achieve: Great results in low light environments, Depth of field control and
Easy manual shooting.
For exceptional optical performance in still and video shooting scenarios, two
aspherical glass elements and two Super-Low Dispersion (SLD) glass elements were
used in order to minimize distortion, manage spherical aberration and
astigmatism while achieving excellent edge-to-edge resolution and contrast
throughout the entire image. Virtually no light fall off occurs at the edges at
all focal lengths.
Coatings
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.
Construction
Tokina incorporated several metal parts inside the lens for a reassuring
build quality and long time utilization in a variety of shooting conditions. The
sophisticated exterior design is specifically developed to match the design of
contemporary DSLR cameras.
Precise attention was also given to zoom and focus ring rotation which has ample
room with no extra wiggle. The coveted one-touch focus clutch mechanism allows
switching between autofocus and manual focus efficiently. The overall length of
the Tokina atx-i 11-16mm f/2.8 CF does not change when focusing and zooming
thanks to the internal construction of the lens.
