The ARRI Amira sensor in numbers
Super 35 (HD–UHD): 26.40 × 14.85 mm, diagonal 30.3 mm. The tables below use a circle of confusion of 0.026 mm (sensor width ÷ 1000) and a 16:9 image taken from the full sensor width, 26.40 × 14.83 mm. A 50 mm lens frames like a 68 mm lens on full frame (factor 1.36).
The same circle of confusion — and therefore the same depth-of-field figures — applies to the Canon EOS C70, the Canon EOS C300 Mark III. Their frame widths differ by less than a millimetre of sensor.
Lens sets from our list that cover the full 30.3 mm diagonal: ARRI Signature Prime, ARRI/Zeiss Master Prime, ARRI/Zeiss Ultra Prime, Zeiss Supreme Prime, Zeiss CP.3, Cooke S4/i, Cooke S7/i Full Frame Plus, Sigma Cine Prime FF, Canon CN-E Prime, Leitz Summicron-C, Tokina Vista Prime, DZOFilm Pictor Zoom.
Up to 200 fps in the manufacturer’s spec — at high frame rates many cameras crop the sensor, which narrows the angle of view; check the recording mode and enter its active area as a custom sensor.
Depth of field on the ARRI Amira at T2.8
Total depth of field (near to far limit) at three working distances. Example: 50 mm at 3 m holds 2.76 m to 3.28 m.
| Focal length | at 1.5 m | at 3.0 m | at 6.0 m |
|---|---|---|---|
| 18 mm | 1.12 m | 7.3 m | ∞ |
| 25 mm | 53 cm | 2.36 m | 16.2 m |
| 35 mm | 26 cm | 1.09 m | 4.87 m |
| 50 mm | 13 cm | 52 cm | 2.14 m |
| 85 mm | 4.3 cm | 18 cm | 72 cm |
| 135 mm | 1.6 cm | 6.9 cm | 28 cm |
Field of view and shot size
What each focal length sees in 16:9 on this sensor, and what that makes of a standing person 3 m away.
| Focal length | Horizontal angle | Frame width at 3 m | Shot size at 3 m | Full-frame equivalent |
|---|---|---|---|---|
| 18 mm | 72.5° | 4.4 m | full shot | 25 mm |
| 25 mm | 55.7° | 3.17 m | full shot | 34 mm |
| 35 mm | 41.3° | 2.26 m | medium long shot | 48 mm |
| 50 mm | 29.6° | 1.58 m | medium shot | 68 mm |
| 85 mm | 17.7° | 93 cm | medium close-up | 116 mm |
| 135 mm | 11.2° | 59 cm | close-up | 184 mm |
Hyperfocal distance
Focus at the hyperfocal distance and everything from half that distance to infinity is acceptably sharp. On the ARRI Amira at T5.6: 4.32 m for 25 mm, 17.2 m for 50 mm.
| Focal length | T2.8 | T5.6 | T11 |
|---|---|---|---|
| 18 mm | 4.47 m | 2.24 m | 1.15 m |
| 25 mm | 8.61 m | 4.32 m | 2.21 m |
| 35 mm | 16.9 m | 8.45 m | 4.32 m |
| 50 mm | 34.4 m | 17.2 m | 8.79 m |
| 85 mm | 99.3 m | 49.7 m | 25.3 m |
| 135 mm | 250.5 m | 125.3 m | 63.9 m |
Frequently asked
What circle of confusion should I use for the ARRI Amira?
0.026 mm follows the cinema convention of sensor width ÷ 1000. For 4K delivery on large screens, or when you judge focus on a big monitor, ÷ 1500 (0.017 mm) is safer — the tool’s “strict” switch does that.
How much depth of field does a 50 mm at T2.8 give on the ARRI Amira?
At 3 m: 52 cm (2.76 m to 3.28 m). At 1.5 m it shrinks to 13 cm.
