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 90 mm | Equiv. aperture (DoF) |
|---|---|---|
| Full frame | 90 mm · 27° | f/2.8 |
| APS-C | 135 mm · 18° | f/4.2 |
| APS-C (Canon) | 144 mm · 17° | f/4.5 |
| Micro Four Thirds | 180 mm · 14° | f/5.6 |
Depth of field & background blur#
Computed on its native Full frame format (CoC 30 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: 85 mm f/2.8 on full frame.
| Focal | Aperture | at 1 m | at 2 m | at 5 m | at 10 m | Hyperfocal | Blur @2 m |
|---|---|---|---|---|---|---|---|
| 90 mm | f/2.8 | 1.9 cm | 7.9 cm | 51.1 cm | 2.08 m | 96.5 m | 4.2% |
| 90 mm | f/4 | 2.7 cm | 11.3 cm | 73.1 cm | 3.00 m | 67.6 m | 2.9% |
| 90 mm | f/8 | 5.4 cm | 22.7 cm | 1.49 m | 6.43 m | 33.8 m | 1.5% |
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 90 mm | NPF at 90 mm, f/2.8 |
|---|---|---|---|
| Full frame | 1/100 s | 6 s | 3 s |
| APS-C | 1/125 s | 4 s | 2 s |
| APS-C (Canon) | 1/160 s | 3 s | 2 s |
| Micro Four Thirds | 1/200 s | 3 s | 2 s |
