Area-based index at equal illumination, f-number and exposure time. Not a camera-quality rating; lens transmission, sensor efficiency and processing are excluded.

Area/aperture estimates assume equal scene brightness and exposure time; full frame at f/2 = 100. Nominal-format estimates assume 4:3. Lens transmission, sensor efficiency and processing are not included.
