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 12 mm	At 17 mm	At 24 mm	Equiv. aperture (DoF)
Full frame	12 mm · 122°	17 mm · 104°	24 mm · 84°	f/4.0
APS-C	18 mm · 99°	26 mm · 79°	36 mm · 61°	f/6.0
APS-C (Canon)	19 mm · 96°	27 mm · 77°	38 mm · 58°	f/6.4
Micro Four Thirds	24 mm · 84°	34 mm · 65°	48 mm · 49°	f/8.0

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/4 on full frame.

Focal	Aperture	at 1 m	at 2 m	at 5 m	at 10 m	Hyperfocal	Blur @2 m
12 mm	f/4	5.11 m	∞	∞	∞	1.21 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).

Body	Min. handheld shutter (longest focal)	500 rule at 12 mm	NPF at 12 mm, f/4
Full frame	1/25 s	42 s	27 s
APS-C	1/40 s	28 s	21 s
APS-C (Canon)	1/40 s	26 s	21 s
