Sigma Contemporary 18-50mm f/2.8 DC DN 18-50mm
Son ouverture constante f/2.8 et son poids plume de 290g en font un zoom transstandard APS-C remarquablement compact, idéal pour ne jamais quitter le boîtier. Sa conception tropicalisée et sa distance minimale de mise au point de 12,1 cm offrent une polyvalence et une robustesse que les fiches techniques ne traduisent pas entièrement. C'est le choix optimal pour les photographes de rue et de portrait cherchant un objectif lumineux et discret sans sacrifier la qualité optique.
