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 7 mm | At 10 mm | At 14 mm | Equiv. aperture (DoF) |
|---|---|---|---|---|
| Micro Four Thirds | 14 mm · 114° | 20 mm · 95° | 28 mm · 75° | 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 |
|---|---|---|---|---|---|---|---|
| 7 mm | f/4 | ∞ | ∞ | ∞ | ∞ | 82.3 cm | 0.0% |
| 7 mm | f/8 | ∞ | ∞ | ∞ | ∞ | 41.5 cm | 0.0% |
| 10 mm | f/4 | 1.84 m | ∞ | ∞ | ∞ | 1.68 m | 0.1% |
| 10 mm | f/8 | ∞ | ∞ | ∞ | ∞ | 84.3 cm | 0.0% |
| 14 mm | f/4 | 66.4 cm | 3.86 m | ∞ | ∞ | 3.28 m | 0.1% |
| 14 mm | f/8 | 1.90 m | ∞ | ∞ | ∞ | 1.65 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 7 mm | NPF at 7 mm, f/4 |
|---|---|---|---|
| Micro Four Thirds | 1/30 s | 36 s | 34 s |
