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 35 mm | At 70 mm | Equiv. aperture (DoF) |
|---|---|---|---|---|
| APS-C | 27 mm · 76° | 52 mm · 44° | 105 mm · 23° | f/5.2 |
| APS-C (Canon) | 29 mm · 73° | 56 mm · 42° | 112 mm · 22° | f/5.6 |
| Micro Four Thirds | 36 mm · 62° | 70 mm · 34° | 140 mm · 18° | 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% |
| 35 mm | f/3.5 | 10.8 cm | 44.5 cm | 3.01 m | 16.1 m | 17.9 m | 0.8% |
| 35 mm | f/4 | 12.4 cm | 51.0 cm | 3.53 m | 21.4 m | 15.7 m | 0.7% |
| 35 mm | f/8 | 25.0 cm | 1.07 m | 10.6 m | ∞ | 7.86 m | 0.3% |
| 70 mm | f/3.5 | 2.6 cm | 10.8 cm | 69.2 cm | 2.83 m | 71.7 m | 3.1% |
| 70 mm | f/4 | 3.0 cm | 12.3 cm | 79.2 cm | 3.25 m | 62.7 m | 2.7% |
| 70 mm | f/8 | 5.9 cm | 24.7 cm | 1.61 m | 7.05 m | 31.4 m | 1.4% |
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 | 1/100 s | 19 s | 13 s |
| APS-C (Canon) | 1/125 s | 17 s | 13 s |
| Micro Four Thirds | 1/125 s | 14 s | 12 s |

Frequently asked questions#
Is the Nikon Nikkor AF-S 18-70mm f/3.5-4.5G DX IF-ED full frame?
No — it is designed for APS-C sensors. On a full-frame body it vignettes or triggers crop mode.
What is the Nikon Nikkor AF-S 18-70mm f/3.5-4.5G DX IF-ED equivalent to on APS-C?
Its focal length is already the real value for APS-C: 18–70 mm frames like 28–107 mm on full frame.
What is the Nikon Nikkor AF-S 18-70mm f/3.5-4.5G DX IF-ED good for?
As a standard zoom it suits everyday shooting, travel, events and walkaround use.
