Depth of field: RED V-Raptor 8K VV
The RED V-Raptor 8K VV uses a Vista Vision 8K sensor at 40.96 × 21.6 mm — which fixes the circle of confusion at 0.041 mm, and from that every depth-of-field number on this page. Example: 50 mm at T2.8 focused at 2 m gives 0.36 m of usable depth (1.84 m to 2.20 m). The calculator above is preset to the RED V-Raptor 8K VV.

Circle of confusion per camera derives from sensor width (d/1000 convention). Camera list: nominal manufacturer specs.
Hyperfocal distance on the RED V-Raptor 8K VV
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 | 5.7 | 4.0 | 2.8 | 2.0 | 1.4 |
| 25 mm | 10.9 | 7.6 | 5.5 | 3.8 | 2.7 |
| 35 mm | 21.4 | 15.0 | 10.7 | 7.5 | 5.4 |
| 50 mm | 43.6 | 30.5 | 21.8 | 15.3 | 10.9 |
| 85 mm | 126.0 | 88.2 | 63.0 | 44.1 | 31.6 |
Depth of field at interview distance (2 m)
The interview question in numbers: how much room does the subject have in front of the RED V-Raptor 8K VV before drifting out of focus?
| Focal length | T1.4 | T2 | T2.8 | T4 | T5.6 |
|---|---|---|---|---|---|
| 35 mm | 0.37 m | 0.54 m | 0.76 m | 1.13 m | 1.70 m |
| 50 mm | 0.18 m | 0.26 m | 0.36 m | 0.52 m | 0.74 m |
| 85 mm | 0.06 m | 0.09 m | 0.12 m | 0.17 m | 0.24 m |
Working with it on set
Recording at 8192 × 4320, large-screen 4K delivery judges focus more harshly than the table: for critical work, halve the circle of confusion mentally — the 0.36 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 RED V-Raptor 8K VV use?
0.041 mm — following the usual sensor-width ÷ 1000 convention (40.96 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.
