Focus Zone Preview
(Subject at 3.0m)
The highlighted range is the idealised acceptable-focus zone for the selected CoC. It is not a pass/fail test for LED moiré or perceived background blur.
Use Cases
Compare lens, aperture, and talent-position options before testing the chosen setup against the actual LED wall and camera chain.
Estimate how quickly acceptable focus narrows in close-up work, then confirm critical focus and lens behaviour on the real set.
Use hyperfocal distance as a planning reference when balancing a physical foreground with distant or virtual background elements.
Determining whether a standard f/4 broadcast zoom lens will provide a shallow enough depth of field for a studio interview, or if a prime f/1.8 cinema lens must be rented.
