Equivalent focal length on different cameras#

Field of view and depth-of-field equivalence when this lens is used on bodies with different sensor sizes (natively or via an adapter).

Camera format	At 18 mm	At 31 mm	At 55 mm	Equiv. aperture (DoF)
APS-C	27 mm · 76°	46 mm · 49°	82 mm · 29°	f/4.2

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/2.8 on aps-c.
