Ultra-wide for Canon and Nikon cropped DSLRs (with an APS-C sensor), which is one of the few that is able to capture the maximum of the surrounding space in the frame (useful when shooting interiors and architecture). The lens was released to replace the Tokina AT-X 11-16mm f/2.8 PRO DX lens, and its maximum focal length has grown to 20 mm. The aperture ratio of the Tokina AT-X 11-20mm f/2.8 PRO DX remains constant over the entire zoom range — its value corresponds to a high f/2.8 mark, as for a class of wide-angle optics. It is noteworthy that when shooting at an open aperture from small distances to the object in the frame (the minimum focus distance of the lens is 28 cm), you can get a spectacular background blur, which is assisted by a 9-blade aperture. The high-quality assembly completes the picture — the model is a “fighter” of the PRO series for good reason.

The All-Seeing Eye from Tokina looks at the world from a wide perspective, allowing you to fit the maximum of the surrounding reality into one frame. In addition, throughout the entire zoom range, the maximum aperture of the lens remains constantly high (f / 2.8), which is a sure sign that the model belongs to a series of top lenses.
PRO level
Once again, the high level of the zoom lens is mentioned in the PRO prefix, which appears in the model name. It encodes not only a high-quality assembly, but also outstanding optical performance. The lens draws a clear picture regardless of the selected focal length, giving maximum razor sharpness at f / 5.6 aperture. However, the f/2.8 aperture is also working for Tokina AT-X 11-20mm f/2.8 PRO DX, with the only caveat that when shooting with an open aperture at the short end of the frame edge, vignetting inevitably spoils.
In one move
The focal length range of 11-20mm is best suited for shooting architecture and interiors. And the aforementioned high f / 2.8 aperture eliminates the need for the lens to be equipped with a built-in stub. The company of a complex optical scheme in the body of the model is only the autofocus mechanism — smart and tenacious, but not quiet enough, which can be critical when shooting video. Focus transfer from automatic mode to manual focus mode and vice versa is carried out by shifting the focus ring towards the mount or front lens (One-touch Focus Clutch).
The nature of the drawing
The aperture of the model is formed from 9 petals and draws spectacular bokeh unusual for wide-angle optics. Petal is also a complete lens hood, which you should definitely use when shooting in backlighting, because. the lens is prone to catching glare. Given the class of optics, it would be useful to mention in the end the complete absence of distortion at the maximum zoom position. But at the short end, there are minor geometric distortions in the frame, but they are easily corrected in the photo editor when post-processing the footage.
