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: 20 mm f/4 on aps-c.

Frequently asked questions#

Is the Canon RF-S 18-150mm F3.5-6.3 IS STM 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 RF-S 18-150mm F3.5-6.3 IS STM equivalent to on APS-C?

Its focal length is already the real value for APS-C: 18–150 mm frames like 28–230 mm on full frame.

What is the Canon RF-S 18-150mm F3.5-6.3 IS STM good for?

As a superzoom it suits travel photography with one lens from wide to telephoto.
