Vous cherchez un boîtier capable de tout faire, du plein soleil à la quasi-obscurité ? Une plage ISO 100-102400 promet exactement cette polyvalence. L’ISO désigne la sensibilité du capteur à la lumière : plus vous la montez, plus vous photographiez dans le sombre, mais plus le bruit numérique (ce grain parasite qui altère l’image) augmente. Tout l’enjeu consiste donc à choisir un boîtier qui préserve la qualité quand la sensibilité grimpe. Ce guide vous explique quelles caractéristiques regarder et quels modèles privilégier, sur la base de nos tests.
