Specifications#
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 12 mm | Equiv. aperture (DoF) |
|---|---|---|
| Full frame | 12 mm · 122° | f/3.1 |
| APS-C | 18 mm · 99° | f/4.7 |
| APS-C (Canon) | 19 mm · 96° | f/5.0 |
| Micro Four Thirds | 24 mm · 84° | f/6.2 |
Depth of field & background blur#
Computed on its native Full frame format (CoC 30 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 full frame.
| Focal | Aperture | at 1 m | at 2 m | at 5 m | at 10 m | Hyperfocal | Blur @2 m |
|---|---|---|---|---|---|---|---|
| 12 mm | f/3.1 | 2.15 m | ∞ | ∞ | ∞ | 1.56 m | 0.1% |
| 12 mm | f/4 | 5.11 m | ∞ | ∞ | ∞ | 1.21 m | 0.1% |
| 12 mm | f/8 | ∞ | ∞ | ∞ | ∞ | 61.2 cm | 0.0% |
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 12 mm | NPF at 12 mm, f/3.1 |
|---|---|---|---|
| Full frame | 1/13 s | 42 s | 24 s |
| APS-C | 1/20 s | 28 s | 19 s |
| APS-C (Canon) | 1/20 s | 26 s | 18 s |
| Micro Four Thirds | 1/25 s | 21 s | 17 s |
