Sensor coverage checker
"Does this lens cover this sensor at this aspect?" Pick a lens (or enter an image circle manually), pick a sensor preset, pick a delivery aspect — the tool does the trig and tells you if the lens covers cleanly, only at the chosen aspect, or vignettes. ARRI Frame Line + Lens Illumination Tool clone.
Pick a lens above (or enter an image circle in mm) to compute coverage.
Lens image circleSensor active areaCrop @ 1.85:1
Sensor active areas pulled from manufacturer datasheets. Image circles from the lens spec sheets — see /tools/frame-lines for a visual frame-line preview at a chosen sensor + aspect. Anamorphic lenses report their stated image circle (the squeeze does not change the optical circle that hits the sensor).
