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 18 mm | At 85 mm | At 400 mm | Equiv. aperture (DoF) |
|---|---|---|---|---|
| APS-C | 27 mm · 76° | 128 mm · 19° | 600 mm · 4° | f/5.2 |
| APS-C (Canon) | 29 mm · 73° | 136 mm · 18° | 640 mm · 4° | f/5.6 |
| Micro Four Thirds | 36 mm · 62° | 170 mm · 15° | 800 mm · 3° | f/7.0 |
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: 20 mm f/4 on aps-c.
| Focal | Aperture | at 1 m | at 2 m | at 5 m | at 10 m | Hyperfocal | Blur @2 m |
|---|---|---|---|---|---|---|---|
| 18 mm | f/3.5 | 43.4 cm | 2.03 m | ∞ | ∞ | 4.75 m | 0.2% |
| 18 mm | f/4 | 50.2 cm | 2.48 m | ∞ | ∞ | 4.16 m | 0.2% |
| 18 mm | f/8 | 1.22 m | 45.6 m | ∞ | ∞ | 2.09 m | 0.1% |
| 85 mm | f/3.5 | 1.7 cm | 7.3 cm | 46.7 cm | 1.90 m | 106 m | 4.6% |
| 85 mm | f/4 | 2.0 cm | 8.3 cm | 53.4 cm | 2.17 m | 92.4 m | 4.0% |
| 85 mm | f/8 | 4.0 cm | 16.6 cm | 1.08 m | 4.50 m | 46.3 m | 2.0% |
| 400 mm | f/3.5 | 0.1 cm | 0.3 cm | 2.0 cm | 8.2 cm | 2.3 km | 121.6% |
| 400 mm | f/4 | 0.1 cm | 0.3 cm | 2.2 cm | 9.4 cm | 2.0 km | 106.4% |
| 400 mm | f/8 | 0.1 cm | 0.6 cm | 4.5 cm | 18.8 cm | 1.0 km | 53.2% |
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 18 mm | NPF at 18 mm, f/3.5 |
|---|---|---|---|
| APS-C | 1/640 s | 19 s | 13 s |
| APS-C (Canon) | 1/640 s | 17 s | 13 s |
| Micro Four Thirds | 1/800 s | 14 s | 12 s |

Frequently asked questions#
Is the Tamron AF 18-400mm f/3.5-6.3 Di II VC HLD (B028) 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 AF 18-400mm f/3.5-6.3 Di II VC HLD (B028) equivalent to on APS-C?
Its focal length is already the real value for APS-C: 18–400 mm frames like 28–614 mm on full frame.
What is the Tamron AF 18-400mm f/3.5-6.3 Di II VC HLD (B028) good for?
As a superzoom it suits travel photography with one lens from wide to telephoto.
