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 15 mm | At 20 mm | Equiv. aperture (DoF) |
|---|---|---|---|---|
| APS-C | 16 mm · 104° | 22 mm · 86° | 30 mm · 70° | f/4.2 |
| APS-C (Canon) | 18 mm · 101° | 24 mm · 84° | 32 mm · 68° | f/4.5 |
| Micro Four Thirds | 22 mm · 89° | 30 mm · 72° | 40 mm · 57° | f/5.6 |
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: 14 mm f/2.8 on aps-c.
| Focal | Aperture | at 1 m | at 2 m | at 5 m | at 10 m | Hyperfocal | Blur @2 m |
|---|---|---|---|---|---|---|---|
| 11 mm | f/2.8 | 1.12 m | 19.0 m | ∞ | ∞ | 2.22 m | 0.1% |
| 11 mm | f/4 | 2.16 m | ∞ | ∞ | ∞ | 1.56 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/2.8 |
|---|---|---|---|
| APS-C | 1/30 s | 30 s | 20 s |
| APS-C (Canon) | 1/30 s | 28 s | 19 s |
| Micro Four Thirds | 1/40 s | 23 s | 18 s |

Frequently asked questions#
Is the Tamron 11-20mm f/2.8 Di III-A RXD (B060) 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 11-20mm f/2.8 Di III-A RXD (B060) equivalent to on APS-C?
Its focal length is already the real value for APS-C: 11–20 mm frames like 17–31 mm on full frame.
What is the Tamron 11-20mm f/2.8 Di III-A RXD (B060) good for?
As a wide-angle zoom it suits landscapes, architecture, interiors and astrophotography.
