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 8 mm	At 12 mm	At 18 mm	Equiv. aperture (DoF)
Micro Four Thirds	16 mm · 107°	24 mm · 84°	36 mm · 62°	f/5.6

Depth of field & background blur#

Computed on its native Four Thirds format (CoC 15 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 four thirds.
