Depth of field: Panasonic AU-EVA1
The Panasonic AU-EVA1 uses a Super 35 5.7K sensor at 24.6 × 12.97 mm — which fixes the circle of confusion at 0.025 mm, and from that every depth-of-field number on this page. Example: 50 mm at T2.8 focused at 2 m gives 0.22 m of usable depth (1.90 m to 2.12 m). The calculator above is preset to the Panasonic AU-EVA1.

Circle of confusion per camera derives from sensor width (d/1000 convention). Camera list: nominal manufacturer specs.
Hyperfocal distance on the Panasonic AU-EVA1
The table is exact for this sensor: the same focal length and stop give different numbers on a camera with a different sensor size — depth of field is a sensor property, not a lens property.
| Focal length | T1.4 | T2 | T2.8 | T4 | T5.6 |
|---|---|---|---|---|---|
| 18 mm | 9.3 | 6.5 | 4.6 | 3.3 | 2.3 |
| 25 mm | 17.9 | 12.5 | 9.0 | 6.3 | 4.5 |
| 35 mm | 35.0 | 24.5 | 17.5 | 12.3 | 8.8 |
| 50 mm | 71.5 | 50.1 | 35.8 | 25.1 | 17.9 |
| 85 mm | 206.5 | 144.6 | 103.3 | 72.3 | 51.7 |
Depth of field at interview distance (2 m)
The interview question in numbers: how much room does the subject have in front of the Panasonic AU-EVA1 before drifting out of focus?
| Focal length | T1.4 | T2 | T2.8 | T4 | T5.6 |
|---|---|---|---|---|---|
| 35 mm | 0.23 m | 0.32 m | 0.45 m | 0.66 m | 0.95 m |
| 50 mm | 0.11 m | 0.16 m | 0.22 m | 0.31 m | 0.44 m |
| 85 mm | 0.04 m | 0.05 m | 0.07 m | 0.11 m | 0.15 m |
Working with it on set
Recording at 4096 × 2160, large-screen 4K delivery judges focus more harshly than the table: for critical work, halve the circle of confusion mentally — the 0.22 m at 50 mm/T2.8/2 m becomes half that. The table follows the classical cinema convention.
In pre-production the number belongs in the shot list: a shot planned at T1.4 on 85 mm needs a focus puller and time — both of which belong in the schedule before they are missing on set.
Frequently asked
What circle of confusion does the Panasonic AU-EVA1 use?
0.025 mm — following the usual sensor-width ÷ 1000 convention (24.6 mm ÷ 1000, rounded). Every table on this page uses it.
Do the numbers hold for any lens?
Yes — depth of field depends on focal length, stop, distance and sensor, not the lens model. What differs between lenses is bokeh (how the blur looks), not where it starts.
