Tokina few days ago released the ATX-i 11-20mm f/2.8 CF: an ultra-wide angle zoom lens for crop-sensor DSLRs from Nikon and Canon. With a fixed f/2.8 aperture.
This lens is an update of one of Tokina’s AT-X 11-20mm f/2.8 PRO DX. The ATX-i moniker means that it’s been updated to work with contemporary DSLRs.
Inside the lens, you’ll find 14 lens elements in 12 groups, including 3 aspherical elements and 3 Super-Low Dispersion (SLD) elements to cut down on distortion, spherical aberration, and astigmatism. Meanwhile, the company’s “anti-reflective multi-layer coating” should cut down on reflections and flare.
In addition to the advertised image quality, the lens boasts a few core features, including: an internal focus and zoom mechanism, a Silent-Drive Motor (SD-M) paired with a “precise GMR sensor” for fast and accurate autofocus, and a one-touch focus clutch mechanism that lets you switch from autofocus to manual focus without by simply turning the focus ring.
Here’s a closer look at the lens
The lens will start shipping on the 10th of July, 2020.
