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/4 on aps-c.

Frequently asked questions#

Is the Canon EF-S 10-22mm f/3.5-4.5 USM full frame?

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

What is the Canon EF-S 10-22mm f/3.5-4.5 USM equivalent to on APS-C?

Its focal length is already the real value for APS-C: 10–22 mm frames like 15–34 mm on full frame.

What is the Canon EF-S 10-22mm f/3.5-4.5 USM good for?

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