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 9 mm | At 13 mm | At 18 mm | Equiv. aperture (DoF) |
|---|---|---|---|---|
| Micro Four Thirds | 18 mm · 100° | 26 mm · 80° | 36 mm · 62° | f/8.0 |
Depth of field & background blur#
Computed on its native Four Thirds format (CoC 15 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/4 on four thirds.
| Focal | Aperture | at 1 m | at 2 m | at 5 m | at 10 m | Hyperfocal | Blur @2 m |
|---|---|---|---|---|---|---|---|
| 9 mm | f/4 | 3.19 m | ∞ | ∞ | ∞ | 1.36 m | 0.1% |
| 9 mm | f/8 | ∞ | ∞ | ∞ | ∞ | 68.4 cm | 0.0% |
| 13 mm | f/4 | 79.9 cm | 5.62 m | ∞ | ∞ | 2.83 m | 0.1% |
| 13 mm | f/8 | 2.76 m | ∞ | ∞ | ∞ | 1.42 m | 0.1% |
| 18 mm | f/4 | 37.6 cm | 1.70 m | 62.2 m | ∞ | 5.42 m | 0.2% |
| 18 mm | f/8 | 83.9 cm | 6.37 m | ∞ | ∞ | 2.72 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 9 mm | NPF at 9 mm, f/4 |
|---|---|---|---|
| Micro Four Thirds | 1/40 s | 28 s | 27 s |
