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)
APS-C	21 mm · 90°	f/4.2
APS-C (Canon)	22 mm · 88°	f/4.5
Micro Four Thirds	28 mm · 75°	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
14 mm	f/2.8	59.6 cm	3.21 m	∞	∞	3.59 m	0.1%
14 mm	f/4	93.1 cm	8.53 m	∞	∞	2.52 m	0.1%
14 mm	f/8	4.14 m	∞	∞	∞	1.27 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 14 mm	NPF at 14 mm, f/2.8

Frequently asked questions#

Is the Fujifilm XF 14mm f/2.8 R full frame?

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

What is the Fujifilm XF 14mm f/2.8 R equivalent to on APS-C?

Its focal length is already the real value for APS-C: 14 mm frames like 21 mm on full frame.

What is the Fujifilm XF 14mm f/2.8 R good for?

As a wide-angle prime it suits street, environmental portraits, landscapes and astro.
