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 85 mm | Equiv. aperture (DoF) |
|---|---|---|
| Full frame | 85 mm · 29° | f/1.8 |
| APS-C | 128 mm · 19° | f/2.7 |
| APS-C (Canon) | 136 mm · 18° | f/2.9 |
| Micro Four Thirds | 170 mm · 15° | f/3.6 |
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/1.8 on full frame.
| Focal | Aperture | at 1 m | at 2 m | at 5 m | at 10 m | Hyperfocal | Blur @2 m |
|---|---|---|---|---|---|---|---|
| 85 mm | f/1.8 | 1.4 cm | 5.7 cm | 36.8 cm | 1.49 m | 134 m | 5.8% |
| 85 mm | f/4 | 3.0 cm | 12.7 cm | 82.2 cm | 3.39 m | 60.3 m | 2.6% |
| 85 mm | f/8 | 6.1 cm | 25.5 cm | 1.68 m | 7.39 m | 30.2 m | 1.3% |
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 85 mm | NPF at 85 mm, f/1.8 |
|---|---|---|---|
| Full frame | 1/80 s | 6 s | 3 s |
| APS-C | 1/125 s | 4 s | 2 s |
| APS-C (Canon) | 1/125 s | 4 s | 2 s |
| Micro Four Thirds | 1/160 s | 3 s | 2 s |
