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 11 mm | At 14 mm | At 18 mm | Equiv. aperture (DoF) |
|---|---|---|---|---|
| APS-C | 16 mm · 104° | 21 mm · 90° | 27 mm · 76° | f/6.8 |
| APS-C (Canon) | 18 mm · 101° | 22 mm · 88° | 29 mm · 73° | f/7.2 |
| Micro Four Thirds | 22 mm · 89° | 28 mm · 75° | 36 mm · 62° | f/9.0 |
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/5.6 on aps-c.
| Focal | Aperture | at 1 m | at 2 m | at 5 m | at 10 m | Hyperfocal | Blur @2 m |
|---|---|---|---|---|---|---|---|
| 11 mm | f/4.5 | 2.98 m | ∞ | ∞ | ∞ | 1.39 m | 0.1% |
| 11 mm | f/8 | ∞ | ∞ | ∞ | ∞ | 78.4 cm | 0.0% |
| 14 mm | f/4.5 | 1.10 m | 17.4 m | ∞ | ∞ | 2.24 m | 0.1% |
| 14 mm | f/8 | 4.14 m | ∞ | ∞ | ∞ | 1.27 m | 0.1% |
| 18 mm | f/4.5 | 57.4 cm | 3.03 m | ∞ | ∞ | 3.70 m | 0.2% |
| 18 mm | f/8 | 1.22 m | 45.6 m | ∞ | ∞ | 2.09 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 11 mm | NPF at 11 mm, f/4.5 |
|---|---|---|---|
| APS-C | 1/25 s | 30 s | 25 s |
| APS-C (Canon) | 1/30 s | 28 s | 24 s |
| Micro Four Thirds | 1/40 s | 23 s | 23 s |

Frequently asked questions#
Is the Tamron SP AF 11-18mm f/4.5-5.6 Di-II LD Aspherical (IF) full frame?
No — it is designed for APS-C sensors. On a full-frame body it vignettes or triggers crop mode.
What is the Tamron SP AF 11-18mm f/4.5-5.6 Di-II LD Aspherical (IF) equivalent to on APS-C?
Its focal length is already the real value for APS-C: 11–18 mm frames like 17–28 mm on full frame.
What is the Tamron SP AF 11-18mm f/4.5-5.6 Di-II LD Aspherical (IF) good for?
As a wide-angle zoom it suits landscapes, architecture, interiors and astrophotography.
