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 45 mm | Equiv. aperture (DoF) |
|---|---|---|
| Full frame | 45 mm · 51° | f/2.8 |
| APS-C | 68 mm · 35° | f/4.2 |
| APS-C (Canon) | 72 mm · 33° | f/4.5 |
| Micro Four Thirds | 90 mm · 27° | f/5.6 |
| Medium format 44×33 | 36 mm · 63° | f/2.2 |
Depth of field & background blur#
Computed on its native Medium format format (CoC 38 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.
| Focal | Aperture | at 1 m | at 2 m | at 5 m | at 10 m | Hyperfocal | Blur @2 m |
|---|---|---|---|---|---|---|---|
| 45 mm | f/2.8 | 10.1 cm | 41.5 cm | 2.79 m | 14.4 m | 19.1 m | 0.8% |
| 45 mm | f/4 | 14.4 cm | 60.0 cm | 4.31 m | 33.8 m | 13.4 m | 0.6% |
| 45 mm | f/8 | 29.3 cm | 1.28 m | 16.6 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 45 mm | NPF at 45 mm, f/2.8 |
|---|---|---|---|
| Full frame | 1/50 s | 11 s | 6 s |
| APS-C | 1/60 s | 7 s | 5 s |
| APS-C (Canon) | 1/80 s | 7 s | 5 s |
| Micro Four Thirds | 1/100 s | 6 s | 4 s |
