Specifications#
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 50 mm | Equiv. aperture (DoF) |
|---|---|---|
| Full frame | 50 mm · 47° | f/2.5 |
| APS-C | 75 mm · 32° | f/3.8 |
| APS-C (Canon) | 80 mm · 30° | f/4.0 |
| Micro Four Thirds | 100 mm · 24° | f/5.0 |
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: 50 mm f/2.8 on full frame.
| Focal | Aperture | at 1 m | at 2 m | at 5 m | at 10 m | Hyperfocal | Blur @2 m |
|---|---|---|---|---|---|---|---|
| 50 mm | f/2.5 | 5.7 cm | 23.5 cm | 1.52 m | 6.55 m | 33.4 m | 1.4% |
| 50 mm | f/4 | 9.1 cm | 37.8 cm | 2.52 m | 12.4 m | 20.9 m | 0.9% |
| 50 mm | f/8 | 18.4 cm | 77.6 cm | 6.14 m | 218 m | 10.5 m | 0.4% |
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 50 mm | NPF at 50 mm, f/2.5 |
|---|---|---|---|
| Full frame | 1/50 s | 10 s | 5 s |
| APS-C | 1/80 s | 7 s | 4 s |
| APS-C (Canon) | 1/80 s | 6 s | 4 s |
| Micro Four Thirds | 1/100 s | 5 s | 4 s |
