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 40 mm	At 77 mm	At 150 mm	Equiv. aperture (DoF)
Micro Four Thirds	80 mm · 30°	154 mm · 16°	300 mm · 8°	f/8.0

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: 40 mm f/4 on four thirds.
