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 33 mm | Equiv. aperture (DoF) |
|---|---|---|
| APS-C | 50 mm · 46° | f/2.1 |
| APS-C (Canon) | 53 mm · 44° | f/2.2 |
| Micro Four Thirds | 66 mm · 36° | f/2.8 |
Depth of field & background blur#
Computed on its native APS-C format (CoC 20 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: 35 mm f/1.4 on aps-c.
| Focal | Aperture | at 1 m | at 2 m | at 5 m | at 10 m | Hyperfocal | Blur @2 m |
|---|---|---|---|---|---|---|---|
| 33 mm | f/1.4 | 4.9 cm | 19.8 cm | 1.27 m | 5.35 m | 39.8 m | 1.7% |
| 33 mm | f/4 | 14.0 cm | 57.7 cm | 4.09 m | 29.4 m | 14.0 m | 0.6% |
| 33 mm | f/8 | 28.3 cm | 1.23 m | 14.5 m | ∞ | 6.99 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 33 mm | NPF at 33 mm, f/1.4 |
|---|---|---|---|
| APS-C | 1/50 s | 10 s | 5 s |
| APS-C (Canon) | 1/50 s | 9 s | 5 s |
| Micro Four Thirds | 1/60 s | 8 s | 4 s |
