Pentax DA 50mm f/1.8 50mm
Son ouverture maximale f/1.8 et son poids plume de 122g en font un objectif remarquablement lumineux et portable pour les montures Pentax K APS-C. Le revêtement SP protège la lentille frontale de la poussière et des traces tout en produisant un bokeh doux grâce à son diaphragme à 7 lamelles. Cet objectif convient parfaitement aux photographes amateurs cherchant un portraitiste abordable ou une focale fixe polyvalente pour la faible luminosité.
