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 12 mm | At 17 mm | At 24 mm | Equiv. aperture (DoF) |
|---|---|---|---|---|
| APS-C | 18 mm · 99° | 26 mm · 79° | 36 mm · 61° | f/6.0 |
| APS-C (Canon) | 19 mm · 96° | 27 mm · 77° | 38 mm · 58° | f/6.4 |
| Micro Four Thirds | 24 mm · 84° | 34 mm · 65° | 48 mm · 49° | f/8.0 |
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: 14 mm f/4 on aps-c.
| Focal | Aperture | at 1 m | at 2 m | at 5 m | at 10 m | Hyperfocal | Blur @2 m |
|---|---|---|---|---|---|---|---|
| 12 mm | f/4 | 1.51 m | ∞ | ∞ | ∞ | 1.85 m | 0.1% |
| 12 mm | f/8 | ∞ | ∞ | ∞ | ∞ | 93.2 cm | 0.0% |
| 17 mm | f/4 | 57.3 cm | 3.02 m | ∞ | ∞ | 3.71 m | 0.2% |
| 17 mm | f/8 | 1.48 m | ∞ | ∞ | ∞ | 1.86 m | 0.1% |
| 24 mm | f/4 | 27.0 cm | 1.16 m | 12.4 m | ∞ | 7.39 m | 0.3% |
| 24 mm | f/8 | 57.0 cm | 3.02 m | ∞ | ∞ | 3.71 m | 0.2% |
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 12 mm | NPF at 12 mm, f/4 |
|---|---|---|---|
| APS-C | 1/40 s | 28 s | 21 s |
| APS-C (Canon) | 1/40 s | 26 s | 21 s |
| Micro Four Thirds | 1/50 s | 21 s | 20 s |

Frequently asked questions#
Is the Tokina AF 12-24mm f/4 AT-X Pro DX full frame?
No — it is designed for APS-C sensors. On a full-frame body it vignettes or triggers crop mode.
What is the Tokina AF 12-24mm f/4 AT-X Pro DX equivalent to on APS-C?
Its focal length is already the real value for APS-C: 12–24 mm frames like 18–37 mm on full frame.
What is the Tokina AF 12-24mm f/4 AT-X Pro DX good for?
As a wide-angle zoom it suits landscapes, architecture, interiors and astrophotography.
