Tokina AT-X PRO DX for digital SLR 11-20mm f/2.8 Pro DX Lens for Nikon F

Description

A versatile wide-angle zoom for Nikon DX-format DSLRs, the AT-X 11-20mm f/2.8
PRO DX Lens from Tokina offers a 16.5-30mm equivalent focal length and
features a constant f/2.8 maximum aperture for maintained brightness
throughout the zoom range. One P-MO hybrid aspherical element and two glass-
molded aspherical element work in tandem to minimize distortions and control
various aberrations while three SD ultra-low dispersion elements reduce
chromatic aberrations for increased clarity. A multi-layer lens coating has
also been applied to further enhance overall light transmission and color
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. Benefitting 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.
Compatible with Nikon DX-format DSLRs, this wide-angle zoom provides a
16.5-30mm equivalent focal length and features a constant f/2.8 maximum
aperture for consistent low-light performance throughout the zoom range.
