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 158 mm | At 500 mm | Equiv. aperture (DoF) |
|---|---|---|---|---|
| Full frame | 50 mm · 47° | 158 mm · 16° | 500 mm · 5° | f/4.5 |
| APS-C | 75 mm · 32° | 237 mm · 10° | 750 mm · 3° | f/6.8 |
| APS-C (Canon) | 80 mm · 30° | 253 mm · 10° | 800 mm · 3° | f/7.2 |
| Micro Four Thirds | 100 mm · 24° | 316 mm · 8° | 1000 mm · 2° | f/9.0 |
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: 50 mm f/5.6 on full frame.
| Focal | Aperture | at 1 m | at 2 m | at 5 m | at 10 m | Hyperfocal | Blur @2 m |
|---|---|---|---|---|---|---|---|
| 50 mm | f/4.5 | 10.3 cm | 42.6 cm | 2.88 m | 15.1 m | 18.6 m | 0.8% |
| 50 mm | f/8 | 18.4 cm | 77.6 cm | 6.14 m | 218 m | 10.5 m | 0.4% |
| 158 mm | f/4.5 | 0.9 cm | 4.0 cm | 26.2 cm | 1.07 m | 185 m | 8.4% |
| 158 mm | f/8 | 1.6 cm | 7.1 cm | 46.7 cm | 1.91 m | 104 m | 4.7% |
| 500 mm | f/4.5 | — | 0.3 cm | 2.4 cm | 10.3 cm | 1.9 km | 102.9% |
| 500 mm | f/8 | — | 0.6 cm | 4.3 cm | 18.2 cm | 1.0 km | 57.9% |
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 50 mm | NPF at 50 mm, f/4.5 |
|---|---|---|---|
| Full frame | 1/500 s | 10 s | 7 s |
| APS-C | 1/800 s | 7 s | 5 s |
| APS-C (Canon) | 1/800 s | 6 s | 5 s |
| Micro Four Thirds | 1/1000 s | 5 s | 5 s |
