Depth of field: Sony Venice 2 (8.6K)
The Sony Venice 2 (8.6K) uses a Full-Frame 8.6K sensor at 35.9 × 24 mm — which fixes the circle of confusion at 0.036 mm, and from that every depth-of-field number on this page. Example: 50 mm at T2.8 focused at 2 m gives 0.32 m of usable depth (1.85 m to 2.17 m). The calculator above is preset to the Sony Venice 2 (8.6K). Because depth of field depends on sensor geometry alone, every number on this page applies unchanged to the Sony Venice (6K) and the Sony FX9 and the Sony FX6 and the Sony FX3 and the Sony Burano and the Blackmagic URSA Cine 12K LF and the Canon EOS R5 C and the Panasonic Lumix S1H and the DJI Ronin 4D 6K and the DJI Inspire 3 (Drohne).

Hyperfocal distance on the Sony Venice 2 (8.6K)
Focused at the hyperfocal distance, sharpness runs from half that distance to infinity — the one number that matters for landscapes, establishers and any shot without a focus puller.
| Focal length | T1.4 | T2 | T2.8 | T4 | T5.6 |
|---|---|---|---|---|---|
| 18 mm | 6.4 | 4.5 | 3.2 | 2.3 | 1.6 |
| 25 mm | 12.4 | 8.7 | 6.2 | 4.4 | 3.1 |
| 35 mm | 24.3 | 17.0 | 12.2 | 8.5 | 6.1 |
| 50 mm | 49.7 | 34.8 | 24.9 | 17.4 | 12.5 |
| 85 mm | 143.4 | 100.4 | 71.8 | 50.3 | 35.9 |
Depth of field at interview distance (2 m)
The interview question in numbers: how much room does the subject have in front of the Sony Venice 2 (8.6K) before drifting out of focus?
| Focal length | T1.4 | T2 | T2.8 | T4 | T5.6 |
|---|---|---|---|---|---|
| 35 mm | 0.33 m | 0.47 m | 0.66 m | 0.98 m | 1.44 m |
| 50 mm | 0.16 m | 0.23 m | 0.32 m | 0.46 m | 0.64 m |
| 85 mm | 0.05 m | 0.08 m | 0.11 m | 0.15 m | 0.21 m |
Working with it on set
Recording at 8640 × 5760, large-screen 4K delivery judges focus more harshly than the table: for critical work, halve the circle of confusion mentally — the 0.32 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 Sony Venice 2 (8.6K) use?
0.036 mm — following the usual sensor-width ÷ 1000 convention (35.9 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.
