The AT-X 116 PRO DX-II 11-16mm f/2.8 Lens for Canon EOS Mount by Tokina is an ultra-wide angle auto-focus zoom lens with a fast f/2.8 aperture throughout the zoom range. The f/2.8 aperture guarantees fast shutter speeds, active auto-focus and minimal blur in low light situations. The AT-X 116 PRO DX-II lens is designed for digital cameras with APS-C-size CMOS or CCD sensors. Its angle of view ranges from 82-104º and it can focus as close as 11.81" (0.3 m). Nine shutter blades in the aperture help to create soft out-of-focus backgrounds and two Super-Low Dispersion glass elements and two aspheric elements help to achieve this lens' excellent contrast, sharpness and minimal chromatic aberration. As an update to their AT-X 116 PRO DX, Tokina has improved the multi-layer coatings to minimize light reflection and improve optical performance. This updated PRO DX-II also has an internal silent focusing motor that allows the lens to utilize auto focus on Nikon cameras that do not have an AF drive gear and motor.
Tokina's One-touch Focus Clutch Mechanism allows the photographer to switch between auto-focus and manual focus with a simple push of the focus ring. Snapping it forward into auto-focus and back into manual focus is all that needs be done, there's no need to adjust the AF/MF switch on the camera body. This is a durable, bright, quality-optic AF lens.
Note! While the lens is designed for APS-C sized sensors it can work on full frame DSLR cameras as well, however some vignetting will occur.
