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 9 mm	Equiv. aperture (DoF)
APS-C	14 mm · 115°	f/4.2
APS-C (Canon)	14 mm · 112°	f/4.5
Micro Four Thirds	18 mm · 100°	f/5.6

Depth of field & background blur#

Computed on its native APS-C format (CoC 20 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 aps-c.

Focal	Aperture	at 1 m	at 2 m	at 5 m	at 10 m	Hyperfocal	Blur @2 m
9 mm	f/2.8	2.43 m	∞	∞	∞	1.49 m	0.1%
9 mm	f/4	22.8 m	∞	∞	∞	1.04 m	0.0%

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 9 mm	NPF at 9 mm, f/2.8

Frequently asked questions#

Is the Laowa 9mm f/2.8 Zero-D full frame?

No — it is designed for APS-C sensors. On a full-frame body it vignettes or triggers crop mode.

What is the Laowa 9mm f/2.8 Zero-D equivalent to on APS-C?

Its focal length is already the real value for APS-C: 9 mm frames like 14 mm on full frame.

What is the Laowa 9mm f/2.8 Zero-D good for?

As a ultra-wide prime it suits astrophotography, landscapes and dramatic perspectives.
