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 18 mm | Equiv. aperture (DoF) |
|---|---|---|
| APS-C | 27 mm · 76° | f/3.0 |
| APS-C (Canon) | 29 mm · 73° | f/3.2 |
| Micro Four Thirds | 36 mm · 62° | f/4.0 |
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: 20 mm f/2 on aps-c.
| Focal | Aperture | at 1 m | at 2 m | at 5 m | at 10 m | Hyperfocal | Blur @2 m |
|---|---|---|---|---|---|---|---|
| 18 mm | f/2 | 24.0 cm | 1.02 m | 9.42 m | ∞ | 8.30 m | 0.3% |
| 18 mm | f/4 | 50.2 cm | 2.48 m | ∞ | ∞ | 4.16 m | 0.2% |
| 18 mm | f/8 | 1.22 m | 45.6 m | ∞ | ∞ | 2.09 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 18 mm | NPF at 18 mm, f/2 |
|---|---|---|---|
| APS-C | 1/25 s | 19 s | 10 s |
| APS-C (Canon) | 1/30 s | 17 s | 10 s |
| Micro Four Thirds | 1/40 s | 14 s | 9 s |

Frequently asked questions#
Is the Fujifilm XF 18mm f/2 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 18mm f/2 R equivalent to on APS-C?
Its focal length is already the real value for APS-C: 18 mm frames like 28 mm on full frame.
What is the Fujifilm XF 18mm f/2 R good for?
As a wide-angle prime it suits street, environmental portraits, landscapes and astro.
