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 23 mm | Equiv. aperture (DoF) |
|---|---|---|
| APS-C | 34 mm · 63° | f/2.1 |
| APS-C (Canon) | 37 mm · 60° | f/2.2 |
| Micro Four Thirds | 46 mm · 50° | 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: 24 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 |
|---|---|---|---|---|---|---|---|
| 23 mm | f/1.4 | 10.1 cm | 41.4 cm | 2.76 m | 14.1 m | 19.3 m | 0.8% |
| 23 mm | f/4 | 29.5 cm | 1.28 m | 16.1 m | ∞ | 6.79 m | 0.3% |
| 23 mm | f/8 | 63.1 cm | 3.55 m | ∞ | ∞ | 3.40 m | 0.1% |
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 23 mm | NPF at 23 mm, f/1.4 |
|---|---|---|---|
| APS-C | 1/30 s | 14 s | 7 s |
| APS-C (Canon) | 1/40 s | 14 s | 7 s |
| Micro Four Thirds | 1/50 s | 11 s | 6 s |

No — it is designed for APS-C sensors. On a full-frame body it vignettes or triggers crop mode.
What is the Viltrox AF 23mm F1.4 XF/Z/L equivalent to on APS-C?
Its focal length is already the real value for APS-C: 23 mm frames like 35 mm on full frame.
What is the Viltrox AF 23mm F1.4 XF/Z/L good for?
As a wide-angle prime it suits street, environmental portraits, landscapes and astro.
