Depth of field & background blur#

Computed on its native APS-C format (CoC 20 µm). “Blur @2 m” is the size of an out-of-focus point at infinity, as a percentage of frame width, with the subject at 2 m — a simple bokeh index. Full table: 14 mm f/2.8 on aps-c.

Frequently asked questions#

Is the Tokina AF 11-16mm f/2.8 AT-X Pro DX full frame?

No — it is designed for APS-C sensors. On a full-frame body it vignettes or triggers crop mode.

What is the Tokina AF 11-16mm f/2.8 AT-X Pro DX equivalent to on APS-C?

Its focal length is already the real value for APS-C: 11–16 mm frames like 17–25 mm on full frame.

What is the Tokina AF 11-16mm f/2.8 AT-X Pro DX good for?

As a wide-angle zoom it suits landscapes, architecture, interiors and astrophotography.
