Spec score
Scores are computed against fixed published anchors (algorithm 1.0.0). See the methodology. Methodology
How much of this score rests on verified data; unknown values shrink toward a neutral 50 and lower the evidence.
Camera scores measure hardware potential (sensor, optics, stabilization) — not lab-tested photo quality.
