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 28 mm | Equiv. aperture (DoF) |
|---|---|---|
| Full frame | 28 mm · 75° | f/1.4 |
| APS-C | 42 mm · 53° | f/2.1 |
| APS-C (Canon) | 45 mm · 51° | f/2.2 |
| Micro Four Thirds | 56 mm · 42° | f/2.8 |
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: 28 mm f/1.4 on full frame.
| Focal | Aperture | at 1 m | at 2 m | at 5 m | at 10 m | Hyperfocal | Blur @2 m |
|---|---|---|---|---|---|---|---|
| 28 mm | f/1.4 | 10.4 cm | 42.7 cm | 2.87 m | 15.0 m | 18.7 m | 0.8% |
| 28 mm | f/4 | 30.4 cm | 1.33 m | 18.1 m | ∞ | 6.56 m | 0.3% |
| 28 mm | f/8 | 65.3 cm | 3.80 m | ∞ | ∞ | 3.29 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 28 mm | NPF at 28 mm, f/1.4 |
|---|---|---|---|
| Full frame | 1/30 s | 18 s | 8 s |
| APS-C | 1/40 s | 12 s | 6 s |
| APS-C (Canon) | 1/50 s | 11 s | 6 s |
| Micro Four Thirds | 1/60 s | 9 s | 5 s |
