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) |
|---|---|---|---|---|
| Full frame | 70 mm · 34° | 145 mm · 17° | 300 mm · 8° | f/4.0 |
| 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 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/4 on full frame.
| Focal | Aperture | at 1 m | at 2 m | at 5 m | at 10 m | Hyperfocal | Blur @2 m |
|---|---|---|---|---|---|---|---|
| 70 mm | f/4 | 4.6 cm | 18.9 cm | 1.23 m | 5.17 m | 40.9 m | 1.8% |
| 70 mm | f/8 | 9.1 cm | 38.2 cm | 2.56 m | 12.7 m | 20.5 m | 0.9% |
| 145 mm | f/4 | 1.0 cm | 4.2 cm | 27.7 cm | 1.13 m | 175 m | 7.9% |
| 145 mm | f/8 | 2.0 cm | 8.5 cm | 55.6 cm | 2.28 m | 87.7 m | 3.9% |
| 300 mm | f/4 | 0.2 cm | 0.9 cm | 6.3 cm | 25.9 cm | 750 m | 36.8% |
| 300 mm | f/8 | 0.4 cm | 1.8 cm | 12.5 cm | 51.8 cm | 375 m | 18.4% |
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 |
|---|---|---|---|
| Full frame | 1/320 s | 7 s | 5 s |
| 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 |
