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 15 mm | Equiv. aperture (DoF) |
|---|---|---|
| Full frame | 15 mm · 111° | f/2.8 |
| APS-C | 22 mm · 86° | f/4.2 |
| APS-C (Canon) | 24 mm · 84° | f/4.5 |
| Micro Four Thirds | 30 mm · 72° | f/5.6 |
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: 16 mm f/2.8 on full frame.
| Focal | Aperture | at 1 m | at 2 m | at 5 m | at 10 m | Hyperfocal | Blur @2 m |
|---|---|---|---|---|---|---|---|
| 15 mm | f/2.8 | 85.0 cm | 6.58 m | ∞ | ∞ | 2.69 m | 0.1% |
| 15 mm | f/4 | 1.45 m | ∞ | ∞ | ∞ | 1.89 m | 0.1% |
| 15 mm | f/8 | ∞ | ∞ | ∞ | ∞ | 95.2 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 15 mm | NPF at 15 mm, f/2.8 |
|---|---|---|---|
| Full frame | 1/15 s | 33 s | 19 s |
| APS-C | 1/25 s | 22 s | 14 s |
| APS-C (Canon) | 1/25 s | 21 s | 14 s |
| Micro Four Thirds | 1/30 s | 17 s | 13 s |
