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 50 mm | At 87 mm | At 150 mm | Equiv. aperture (DoF) |
|---|---|---|---|---|
| APS-C | 75 mm · 32° | 130 mm · 18° | 225 mm · 11° | f/4.2 |
| APS-C (Canon) | 80 mm · 30° | 139 mm · 18° | 240 mm · 10° | f/4.5 |
| Micro Four Thirds | 100 mm · 24° | 174 mm · 14° | 300 mm · 8° | f/5.6 |
Depth of field & background blur#
Computed on its native APS-C format (CoC 20 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: 50 mm f/2.8 on aps-c.
| Focal | Aperture | at 1 m | at 2 m | at 5 m | at 10 m | Hyperfocal | Blur @2 m |
|---|---|---|---|---|---|---|---|
| 50 mm | f/2.8 | 4.2 cm | 17.1 cm | 1.10 m | 4.58 m | 45.7 m | 1.9% |
| 50 mm | f/4 | 6.0 cm | 24.5 cm | 1.59 m | 6.90 m | 32.0 m | 1.4% |
| 50 mm | f/8 | 11.9 cm | 49.6 cm | 3.43 m | 20.3 m | 16.0 m | 0.7% |
| 87 mm | f/2.8 | 1.3 cm | 5.5 cm | 35.6 cm | 1.44 m | 138 m | 6.0% |
| 87 mm | f/4 | 1.9 cm | 7.9 cm | 50.9 cm | 2.07 m | 96.8 m | 4.2% |
| 87 mm | f/8 | 3.8 cm | 15.8 cm | 1.03 m | 4.28 m | 48.5 m | 2.1% |
| 150 mm | f/2.8 | 0.4 cm | 1.8 cm | 11.8 cm | 48.0 cm | 411 m | 18.5% |
| 150 mm | f/4 | 0.6 cm | 2.6 cm | 16.9 cm | 68.6 cm | 288 m | 12.9% |
| 150 mm | f/8 | 1.2 cm | 5.1 cm | 33.8 cm | 1.38 m | 144 m | 6.5% |
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 50 mm | NPF at 50 mm, f/2.8 |
|---|---|---|---|
| APS-C | 1/250 s | 7 s | 4 s |
| APS-C (Canon) | 1/250 s | 6 s | 4 s |
| Micro Four Thirds | 1/320 s | 5 s | 4 s |

What is the Sigma 50-150mm f/2.8 APO EX DC HSM II equivalent to on APS-C?
Its focal length is already the real value for APS-C: 50–150 mm frames like 77–230 mm on full frame.
What is the Sigma 50-150mm f/2.8 APO EX DC HSM II good for?
As a telephoto zoom it suits sport, wildlife, events and compressed landscapes.
