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 24 mm | Equiv. aperture (DoF) |
|---|---|---|
| Full frame | 24 mm · 84° | f/3.5 |
| APS-C | 36 mm · 61° | f/5.2 |
| APS-C (Canon) | 38 mm · 58° | f/5.6 |
| Micro Four Thirds | 48 mm · 49° | f/7.0 |
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: 24 mm f/4 on full frame.
| Focal | Aperture | at 1 m | at 2 m | at 5 m | at 10 m | Hyperfocal | Blur @2 m |
|---|---|---|---|---|---|---|---|
| 24 mm | f/3.5 | 36.7 cm | 1.66 m | 51.2 m | ∞ | 5.51 m | 0.2% |
| 24 mm | f/4 | 42.4 cm | 1.98 m | ∞ | ∞ | 4.82 m | 0.2% |
| 24 mm | f/8 | 97.4 cm | 10.2 m | ∞ | ∞ | 2.42 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 24 mm | NPF at 24 mm, f/3.5 |
|---|---|---|---|
| Full frame | 1/25 s | 21 s | 13 s |
| APS-C | 1/40 s | 14 s | 10 s |
| APS-C (Canon) | 1/40 s | 13 s | 10 s |
| Micro Four Thirds | 1/50 s | 10 s | 9 s |
