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 80 mm | At 179 mm | At 400 mm | Equiv. aperture (DoF) |
|---|---|---|---|---|
| Full frame | 80 mm · 30° | 179 mm · 14° | 400 mm · 6° | f/4.5 |
| APS-C | 120 mm · 20° | 268 mm · 9° | 600 mm · 4° | f/6.8 |
| APS-C (Canon) | 128 mm · 19° | 286 mm · 9° | 640 mm · 4° | f/7.2 |
| Micro Four Thirds | 160 mm · 15° | 358 mm · 7° | 800 mm · 3° | 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: 85 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 |
|---|---|---|---|---|---|---|---|
| 80 mm | f/4.5 | 3.9 cm | 16.2 cm | 1.05 m | 4.38 m | 47.5 m | 2.1% |
| 80 mm | f/8 | 6.9 cm | 29.0 cm | 1.91 m | 8.63 m | 26.7 m | 1.2% |
| 179 mm | f/4.5 | 0.7 cm | 3.1 cm | 20.3 cm | 82.9 cm | 238 m | 10.9% |
| 179 mm | f/8 | 1.2 cm | 5.5 cm | 36.2 cm | 1.48 m | 134 m | 6.1% |
| 400 mm | f/4.5 | 0.1 cm | 0.5 cm | 3.9 cm | 16.2 cm | 1.2 km | 61.7% |
| 400 mm | f/8 | 0.2 cm | 1.0 cm | 6.9 cm | 28.8 cm | 667 m | 34.7% |
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 80 mm | NPF at 80 mm, f/4.5 |
|---|---|---|---|
| Full frame | 1/400 s | 6 s | 4 s |
| APS-C | 1/640 s | 4 s | 3 s |
| APS-C (Canon) | 1/640 s | 4 s | 3 s |
| Micro Four Thirds | 1/800 s | 3 s | 3 s |
