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 16 mm	Equiv. aperture (DoF)
Micro Four Thirds	32 mm · 68°	f/2.8

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: 16 mm f/1.4 on four thirds.

Focal	Aperture	at 1 m	at 2 m	at 5 m	at 10 m	Hyperfocal	Blur @2 m
16 mm	f/1.4	16.3 cm	66.9 cm	4.91 m	49.8 m	12.2 m	0.5%
16 mm	f/4	48.7 cm	2.37 m	∞	∞	4.28 m	0.2%
16 mm	f/8	1.17 m	27.7 m	∞	∞	2.15 m	0.1%

Handheld & night-sky limits#

NPF assumes typical 20–24 MP sensors (≈6 µm pixels on full frame, ≈3.9 µm on APS-C, ≈3.3 µm on Micro Four Thirds).
