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 28 mm | Equiv. aperture (DoF) |
|---|---|---|
| APS-C | 42 mm · 53° | f/5.2 |
| APS-C (Canon) | 45 mm · 51° | f/5.6 |
| Micro Four Thirds | 56 mm · 42° | 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: 28 mm f/4 on aps-c.
| Focal | Aperture | at 1 m | at 2 m | at 5 m | at 10 m | Hyperfocal | Blur @2 m |
|---|---|---|---|---|---|---|---|
| 28 mm | f/3.5 | 17.1 cm | 71.0 cm | 5.35 m | 72.0 m | 11.5 m | 0.5% |
| 28 mm | f/4 | 19.6 cm | 81.9 cm | 6.58 m | 2.0 km | 10.0 m | 0.4% |
| 28 mm | f/8 | 40.3 cm | 1.86 m | 643 m | ∞ | 5.04 m | 0.2% |
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 28 mm | NPF at 28 mm, f/3.5 |
|---|---|---|---|
| APS-C | 1/40 s | 12 s | 9 s |
| APS-C (Canon) | 1/50 s | 11 s | 8 s |
| Micro Four Thirds | 1/60 s | 9 s | 8 s |

Frequently asked questions#
Is the Canon EF-M 28mm f/3.5 Macro 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 28mm f/3.5 Macro IS STM equivalent to on APS-C?
Its focal length is already the real value for APS-C: 28 mm frames like 43 mm on full frame.
What is the Canon EF-M 28mm f/3.5 Macro IS STM good for?
As a macro it suits close-ups of insects, flowers, products and details at up to life size.
