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 25 mm | Equiv. aperture (DoF) |
|---|---|---|
| Full frame | 25 mm · 82° | f/1.7 |
| APS-C | 38 mm · 59° | f/2.5 |
| APS-C (Canon) | 40 mm · 56° | f/2.7 |
| Micro Four Thirds | 50 mm · 47° | f/3.4 |
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/1.8 on full frame.
| Focal | Aperture | at 1 m | at 2 m | at 5 m | at 10 m | Hyperfocal | Blur @2 m |
|---|---|---|---|---|---|---|---|
| 25 mm | f/1.7 | 16.0 cm | 66.2 cm | 4.86 m | 48.2 m | 12.3 m | 0.5% |
| 25 mm | f/4 | 38.8 cm | 1.77 m | 109 m | ∞ | 5.23 m | 0.2% |
| 25 mm | f/8 | 87.1 cm | 7.14 m | ∞ | ∞ | 2.63 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 25 mm | NPF at 25 mm, f/1.7 |
|---|---|---|---|
| Full frame | 1/25 s | 20 s | 10 s |
| APS-C | 1/40 s | 13 s | 7 s |
| APS-C (Canon) | 1/40 s | 12 s | 7 s |
| Micro Four Thirds | 1/50 s | 10 s | 6 s |
