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 35 mm | Equiv. aperture (DoF) |
|---|---|---|
| APS-C | 52 mm · 44° | f/2.7 |
| APS-C (Canon) | 56 mm · 42° | f/2.9 |
| Micro Four Thirds | 70 mm · 34° | f/3.6 |
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/1.8 on aps-c.
| Focal | Aperture | at 1 m | at 2 m | at 5 m | at 10 m | Hyperfocal | Blur @2 m |
|---|---|---|---|---|---|---|---|
| 35 mm | f/1.8 | 5.6 cm | 22.7 cm | 1.46 m | 6.24 m | 34.8 m | 1.5% |
| 35 mm | f/4 | 12.4 cm | 51.0 cm | 3.53 m | 21.4 m | 15.7 m | 0.7% |
| 35 mm | f/8 | 25.0 cm | 1.07 m | 10.6 m | ∞ | 7.86 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 35 mm | NPF at 35 mm, f/1.8 |
|---|---|---|---|
| APS-C | 1/50 s | 10 s | 5 s |
| APS-C (Canon) | 1/60 s | 9 s | 5 s |
| Micro Four Thirds | 1/80 s | 7 s | 5 s |

No — it is designed for APS-C sensors. On a full-frame body it vignettes or triggers crop mode.
What is the Sony DT 35mm f/1.8 SAM equivalent to on APS-C?
Its focal length is already the real value for APS-C: 35 mm frames like 54 mm on full frame.
What is the Sony DT 35mm f/1.8 SAM good for?
As a standard prime it suits street, documentary, everyday and low-light shooting.
