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 71 mm | At 100 mm | Equiv. aperture (DoF) |
|---|---|---|---|---|
| APS-C | 75 mm · 32° | 106 mm · 22° | 150 mm · 16° | f/2.7 |
| APS-C (Canon) | 80 mm · 30° | 114 mm · 21° | 160 mm · 15° | f/2.9 |
| Micro Four Thirds | 100 mm · 24° | 142 mm · 17° | 200 mm · 12° | f/3.6 |
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/1.8 on aps-c.
| Focal | Aperture | at 1 m | at 2 m | at 5 m | at 10 m | Hyperfocal | Blur @2 m |
|---|---|---|---|---|---|---|---|
| 50 mm | f/1.8 | 2.7 cm | 11.0 cm | 70.0 cm | 2.86 m | 71.1 m | 3.0% |
| 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% |
| 71 mm | f/1.8 | 1.3 cm | 5.4 cm | 34.5 cm | 1.39 m | 143 m | 6.2% |
| 71 mm | f/4 | 2.9 cm | 12.0 cm | 76.9 cm | 3.16 m | 64.5 m | 2.8% |
| 71 mm | f/8 | 5.8 cm | 24.0 cm | 1.57 m | 6.81 m | 32.3 m | 1.4% |
| 100 mm | f/1.8 | 0.6 cm | 2.7 cm | 17.3 cm | 69.8 cm | 284 m | 12.4% |
| 100 mm | f/4 | 1.4 cm | 5.9 cm | 38.4 cm | 1.56 m | 128 m | 5.6% |
| 100 mm | f/8 | 2.8 cm | 11.9 cm | 77.1 cm | 3.17 m | 64.0 m | 2.8% |
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/1.8 |
|---|---|---|---|
| APS-C | 1/160 s | 7 s | 4 s |
| APS-C (Canon) | 1/160 s | 6 s | 3 s |
| Micro Four Thirds | 1/200 s | 5 s | 3 s |

Frequently asked questions#
Is the Sigma 50-100mm f/1.8 DC HSM Art full frame?
No — it is designed for APS-C sensors. On a full-frame body it vignettes or triggers crop mode.
What is the Sigma 50-100mm f/1.8 DC HSM Art equivalent to on APS-C?
Its focal length is already the real value for APS-C: 50–100 mm frames like 77–153 mm on full frame.
What is the Sigma 50-100mm f/1.8 DC HSM Art good for?
As a telephoto zoom it suits sport, wildlife, events and compressed landscapes.
