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 40 mm | Equiv. aperture (DoF) |
|---|---|---|
| Full frame | 40 mm · 57° | f/2.0 |
| APS-C | 60 mm · 39° | f/3.0 |
| APS-C (Canon) | 64 mm · 37° | f/3.2 |
| Micro Four Thirds | 80 mm · 30° | f/4.0 |
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: 40 mm f/2 on full frame.
| Focal | Aperture | at 1 m | at 2 m | at 5 m | at 10 m | Hyperfocal | Blur @2 m |
|---|---|---|---|---|---|---|---|
| 40 mm | f/2 | 7.2 cm | 29.6 cm | 1.93 m | 8.68 m | 26.7 m | 1.1% |
| 40 mm | f/4 | 14.5 cm | 60.1 cm | 4.32 m | 33.8 m | 13.4 m | 0.6% |
| 40 mm | f/8 | 29.4 cm | 1.29 m | 16.7 m | ∞ | 6.71 m | 0.3% |
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 40 mm | NPF at 40 mm, f/2 |
|---|---|---|---|
| Full frame | 1/40 s | 12 s | 6 s |
| APS-C | 1/60 s | 8 s | 5 s |
| APS-C (Canon) | 1/60 s | 8 s | 5 s |
| Micro Four Thirds | 1/80 s | 6 s | 4 s |
