Metered against a dim indoor scene, EV 3. Motion assumes a subject crossing the frame at a 3 mph walk. Blur figures are millimetres on the sensor, the way lens data is always quoted.

What this does not simulate

Lens-specific bokeh, sharpness, autofocus and aberrations require real-world testing. This preview estimates blur size from a thin-lens model and scene depth. It is an educational simulation, not a measured optical test.
