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 30 mm | Equiv. aperture (DoF) |
|---|---|---|
| APS-C | 45 mm · 50° | f/4.2 |
| APS-C (Canon) | 48 mm · 48° | f/4.5 |
| Micro Four Thirds | 60 mm · 40° | 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: 28 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 |
|---|---|---|---|---|---|---|---|
| 30 mm | f/2.8 | 11.8 cm | 48.6 cm | 3.33 m | 19.2 m | 16.5 m | 0.7% |
| 30 mm | f/4 | 17.0 cm | 70.6 cm | 5.31 m | 69.6 m | 11.5 m | 0.5% |
| 30 mm | f/8 | 34.7 cm | 1.55 m | 34.1 m | ∞ | 5.78 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 30 mm | NPF at 30 mm, f/2.8 |
|---|---|---|---|
| APS-C | 1/50 s | 11 s | 7 s |
| APS-C (Canon) | 1/50 s | 10 s | 7 s |
| Micro Four Thirds | 1/60 s | 8 s | 7 s |
