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 14 mm	Equiv. aperture (DoF)
Full frame	14 mm · 114°	f/1.8
APS-C	21 mm · 90°	f/2.7
APS-C (Canon)	22 mm · 88°	f/2.9
Micro Four Thirds	28 mm · 75°	f/3.6

Depth of field & background blur#

Computed on its native Full frame format (CoC 30 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/1.8 on full frame.

Focal	Aperture	at 1 m	at 2 m	at 5 m	at 10 m	Hyperfocal	Blur @2 m
14 mm	f/1.8	58.7 cm	3.12 m	∞	∞	3.64 m	0.2%

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).
