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 70 mm | At 145 mm | At 300 mm | Equiv. aperture (DoF) |
|---|---|---|---|---|
| APS-C | 105 mm · 23° | 218 mm · 11° | 450 mm · 5° | f/6.0 |
| APS-C (Canon) | 112 mm · 22° | 232 mm · 11° | 480 mm · 5° | f/6.4 |
| Micro Four Thirds | 140 mm · 18° | 290 mm · 9° | 600 mm · 4° | f/8.0 |
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: 85 mm f/4 on aps-c.
| Focal | Aperture | at 1 m | at 2 m | at 5 m | at 10 m | Hyperfocal | Blur @2 m |
|---|---|---|---|---|---|---|---|
| 70 mm | f/4 | 3.0 cm | 12.3 cm | 79.2 cm | 3.25 m | 62.7 m | 2.7% |
| 70 mm | f/8 | 5.9 cm | 24.7 cm | 1.61 m | 7.05 m | 31.4 m | 1.4% |
| 145 mm | f/4 | 0.6 cm | 2.8 cm | 18.1 cm | 73.4 cm | 269 m | 12.1% |
| 145 mm | f/8 | 1.3 cm | 5.5 cm | 36.2 cm | 1.47 m | 135 m | 6.0% |
| 300 mm | f/4 | 0.1 cm | 0.6 cm | 4.1 cm | 16.9 cm | 1.2 km | 56.3% |
| 300 mm | f/8 | 0.2 cm | 1.2 cm | 8.2 cm | 33.7 cm | 576 m | 28.2% |
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 70 mm | NPF at 70 mm, f/4 |
|---|---|---|---|
| APS-C | 1/500 s | 5 s | 4 s |
| APS-C (Canon) | 1/500 s | 4 s | 4 s |
| Micro Four Thirds | 1/640 s | 4 s | 3 s |
