Introducing this Tokina Lens allowing you to Capture Super Wide-Angle of View while Maintaining your Subject! 

The highly innovative Tokina Cinema Vista 16-28mm II T3 Wide-Angle Zoom Lens (F Mount) features a parfocal design, a T3.0 aperture throughout its zoom range, holds focus throughout the zoom range, and does not ramp exposure as you get to the extremes of the zoom range. The 16-28mm lens has been re-engineered to meet the demanding needs of the professional cinematographer. Using the successful optical formula of the award-winning still lens, Tokina engineers have created a lens that is parfocal, has dramatically reduced breathing and image shift and has a de-clicked, 9-bladed, curved iris for beautiful bokeh and precise exposure control. With its 28cm close-focus capability, the lens allows you the freedom to capture a super wide angle of view while still maintaining a tight perspective on your subject.

This lens is designed to provide sharp images even when recording images at 8K resolution and covers full-frame sensors. The lens design also reduces the breathing and image shift sometimes encountered while zooming and focusing. It uses aspherical elements and super-low dispersion glass in its optical design for optimal color correction and minimal distortion.
