Coverage

Does it cover? Know before the truck.

Pick a camera, a sensor mode and a lens. Coverage draws what that glass actually throws onto that sensor, to scale.

Projection

The image circle, its falloff, and where the corners go dark.

Light loss follows the T-stop you set and the lens's own data. Turn on the test chart and focus falloff to see how sharp the edges stay.

Two cameras or two lenses, side by side.

Line up an 8mm against a 25mm, or the same lens on two sensors. Specs sit in two columns, row for row, and the export is a landscape sheet you can send to the producer.
