Featuring that fast f/2.8 maximum aperture throughout the focal range, the effective focal length on Nikon DSLRs translates to 16.5-30mm and 17.6-32mm on Canon DSLRs thanks to the 1.6x crop factor. This range makes the lens suitable for a wide range of photography, including landscapes, architecture and astrophotography, along with more wider general travel image-making.
Fairly lightweight and compact, the Nikon version of the lens tips the scales at 550g (with the Canon version 20g heavier) and features an internal focusing design, making it easy for photographers to add filters to the front of the lens via the 82mm thread.
Powered by an internal Silent-Drive focusing Motor (SD-M), the atx-i 11-20mm F2.8 CF also includes a one-touch focus Clutch mechanism, enabling users to switch between autofocus and manual focus easily and quickly during operation.
Tokina explains the atx-i 11-20mm F2.8 CF features three Super-Low Dispersion glass elements to ‘minimise distortion, manage spherical aberration and astigmatism’ and the lens also includes anti-reflective multi-layer coating to ‘improves light transmission and minimises reflections’.
The atx-i 11-20mm F2.8 CF may well also be a wise choice for crop sensor photographers who also like to shoot video, with the Tokina lens featuring minimal focus breathing and that fast f/2,8 aperture to create arty shallow depths of field in your footage. The Tokina atx-i 11-20mm F2.8 CF is expected to be available from July.
