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 | At 31 mm | At 55 mm | Equiv. aperture (DoF) |
|---|---|---|---|---|
| APS-C | 27 mm · 76° | 46 mm · 49° | 82 mm · 29° | f/5.2 |
| APS-C (Canon) | 29 mm · 73° | 50 mm · 47° | 88 mm · 27° | f/5.6 |
| Micro Four Thirds | 36 mm · 62° | 62 mm · 38° | 110 mm · 22° | f/7.0 |
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/4 on aps-c.
| Focal | Aperture | at 1 m | at 2 m | at 5 m | at 10 m | Hyperfocal | Blur @2 m |
|---|---|---|---|---|---|---|---|
| 18 mm | f/3.5 | 43.4 cm | 2.03 m | ∞ | ∞ | 4.75 m | 0.2% |
| 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% |
| 31 mm | f/3.5 | 13.9 cm | 57.2 cm | 4.05 m | 28.6 m | 14.1 m | 0.6% |
| 31 mm | f/4 | 15.9 cm | 65.8 cm | 4.84 m | 47.5 m | 12.3 m | 0.5% |
| 31 mm | f/8 | 32.4 cm | 1.43 m | 23.4 m | ∞ | 6.17 m | 0.3% |
| 55 mm | f/3.5 | 4.3 cm | 17.6 cm | 1.13 m | 4.74 m | 44.2 m | 1.9% |
| 55 mm | f/4 | 4.9 cm | 20.2 cm | 1.30 m | 5.51 m | 38.7 m | 1.7% |
| 55 mm | f/8 | 9.8 cm | 40.7 cm | 2.74 m | 14.0 m | 19.4 m | 0.8% |
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/3.5 |
|---|---|---|---|
| APS-C | 1/80 s | 19 s | 13 s |
| APS-C (Canon) | 1/80 s | 17 s | 13 s |
| Micro Four Thirds | 1/100 s | 14 s | 12 s |

Frequently asked questions#
Is the Canon EF-M 18-55mm f/3.5-5.6 IS STM full frame?
No — it is designed for APS-C sensors. On a full-frame body it vignettes or triggers crop mode.
What is the Canon EF-M 18-55mm f/3.5-5.6 IS STM equivalent to on APS-C?
Its focal length is already the real value for APS-C: 18–55 mm frames like 28–84 mm on full frame.
What is the Canon EF-M 18-55mm f/3.5-5.6 IS STM good for?
As a standard zoom it suits everyday shooting, travel, events and walkaround use.
