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 | At 41 mm | At 70 mm | Equiv. aperture (DoF) |
|---|---|---|---|---|
| Full frame | 24 mm · 84° | 41 mm · 56° | 70 mm · 34° | f/2.8 |
| APS-C | 36 mm · 61° | 62 mm · 38° | 105 mm · 23° | f/4.2 |
| APS-C (Canon) | 38 mm · 58° | 66 mm · 36° | 112 mm · 22° | f/4.5 |
| Micro Four Thirds | 48 mm · 49° | 82 mm · 30° | 140 mm · 18° | 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: 24 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 |
|---|---|---|---|---|---|---|---|
| 24 mm | f/2.8 | 29.1 cm | 1.26 m | 15.3 m | ∞ | 6.88 m | 0.3% |
| 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% |
| 41 mm | f/2.8 | 9.6 cm | 39.5 cm | 2.64 m | 13.2 m | 20.1 m | 0.9% |
| 41 mm | f/4 | 13.8 cm | 57.1 cm | 4.05 m | 28.7 m | 14.0 m | 0.6% |
| 41 mm | f/8 | 27.9 cm | 1.21 m | 14.2 m | ∞ | 7.05 m | 0.3% |
| 70 mm | f/2.8 | 3.2 cm | 13.2 cm | 85.1 cm | 3.51 m | 58.4 m | 2.5% |
| 70 mm | f/4 | 4.6 cm | 18.9 cm | 1.23 m | 5.17 m | 40.9 m | 1.8% |
| 70 mm | f/8 | 9.1 cm | 38.2 cm | 2.56 m | 12.7 m | 20.5 m | 0.9% |
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/2.8 |
|---|---|---|---|
| Full frame | 1/80 s | 21 s | 12 s |
| APS-C | 1/100 s | 14 s | 9 s |
| APS-C (Canon) | 1/125 s | 13 s | 9 s |
| Micro Four Thirds | 1/125 s | 10 s | 8 s |
