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 14 mm | Equiv. aperture (DoF) |
|---|---|---|
| Full frame | 14 mm · 114° | f/1.8 |
| APS-C | 21 mm · 90° | f/2.7 |
| APS-C (Canon) | 22 mm · 88° | f/2.9 |
| Micro Four Thirds | 28 mm · 75° | f/3.6 |
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/1.8 on full frame.
| Focal | Aperture | at 1 m | at 2 m | at 5 m | at 10 m | Hyperfocal | Blur @2 m |
|---|---|---|---|---|---|---|---|
| 14 mm | f/1.8 | 58.7 cm | 3.12 m | ∞ | ∞ | 3.64 m | 0.2% |
| 14 mm | f/4 | 1.90 m | ∞ | ∞ | ∞ | 1.65 m | 0.1% |
| 14 mm | f/8 | ∞ | ∞ | ∞ | ∞ | 83.1 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 14 mm | NPF at 14 mm, f/1.8 |
|---|---|---|---|
| Full frame | 1/15 s | 36 s | 17 s |
| APS-C | 1/20 s | 24 s | 13 s |
| APS-C (Canon) | 1/25 s | 22 s | 12 s |
| Micro Four Thirds | 1/30 s | 18 s | 12 s |
