The Tokina AT-X 11-20mm F2.8 PRO DX ultra-wide angle lens in CANON EF mount features an expanded telephoto zoom range and improved optical performance. The lens is designed for use with Canon EOS DSLR cameras with APS-C (DX) cropped sensors. Tokina adds to its family of fast-aperture wide-angle zooms focused on providing photographers professional quality optics and construction at an affordable price. The fast F2.8 aperture lens offers an equivalent 17.5-32mm zoom range. The new proprietary optical design uses three aspherical lens elements (2 all-glass moulded and 1 P-MO hybrid) to achieve superior contrast, sharpness, and correct for spherical aberrations. Additionally, Tokina uses three SD (super-low Dispersion, “FK01” and FK03”) glass elements to control chromatic aberrations. This compact ultra wide-angle zoom lens has a bright, constant F2.8 aperture making viewing and auto focus possible in low light situations but still maintaining portable size and weight.
The Tokina 11-20mm is a versatile wide-angle zoom for Nikon DX-format DSLRs, the constant f/2.8 maximum aperture is maintained brightness throughout the zoom range. A multi-layer lens coating has also been applied to further enhance overall light transmission and colour accuracy by suppressing lens flare and ghosting. Well-suited to working in a wide variety of situations, this ultra-wide zoom covers an array of wide-angle perspectives while maintaining consistent illumination for working in challenging lighting.
Benefiting the usability, a one-touch focusing clutch permits quick switching between autofocus and manual focus modes, and an internal focusing design maintains the overall length of the lens during use. The medium-torque focusing ring further benefits precise handling by allowing for refined control when manually focusing. Additionally, this lens sees the incorporation of a nine-blade diaphragm, which contributes to a pleasing out-of-focus quality when employing shallow depth of field shooting techniques.
