| Camera format | At 28 mm | At 46 mm | At 75 mm | Equiv. aperture (DoF) |
|---|---|---|---|---|
| Full frame | 28 mm · 75° | 46 mm · 50° | 75 mm · 32° | f/2.8 |
| APS-C | 42 mm · 53° | 69 mm · 34° | 112 mm · 21° | f/4.2 |

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/2.8 on full frame.
| Focal | Aperture | at 1 m | at 2 m | at 5 m | at 10 m | Hyperfocal | Blur @2 m |
|---|---|---|---|---|---|---|---|
| 28 mm | f/2.8 | 21.1 cm | 88.5 cm | 7.44 m | ∞ | 9.36 m | 0.4% |
| 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% |
| 46 mm | f/2.8 | 7.6 cm | 31.2 cm | 2.05 m | 9.37 m | 25.2 m | 1.1% |
| 46 mm | f/4 | 10.9 cm | 44.9 cm | 3.05 m | 16.6 m | 17.7 m | 0.8% |
| 46 mm | f/8 | 21.9 cm | 93.2 cm | 8.21 m | ∞ | 8.86 m | 0.4% |
| 75 mm | f/2.8 | 2.8 cm | 11.5 cm | 73.9 cm | 3.03 m | 67.0 m | 2.9% |
| 75 mm | f/4 | 3.9 cm | 16.5 cm | 1.06 m | 4.43 m | 47.0 m | 2.0% |
| 75 mm | f/8 | 7.9 cm | 33.1 cm | 2.20 m | 10.3 m | 23.5 m | 1.0% |
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 28 mm | NPF at 28 mm, f/2.8 |
|---|---|---|---|
| Full frame | 1/80 s | 18 s | 10 s |
| APS-C | 1/125 s | 12 s | 8 s |
| APS-C (Canon) | 1/125 s | 11 s | 7 s |
