TTArtisan 7.5mm F2.0 8mm
Son ouverture lumineuse f/2.0 et sa distance de mise au point minimale de 12,5 cm permettent des gros plans exagérés avec un bokeh créatif, malgré une mise au point entièrement manuelle. Sa conception optique incluant 2 éléments ED et son pare-soleil intégré offrent une qualité d'image solide pour un objectif fisheye à ce positionnement tarifaire. Cet objectif est idéal pour les photographes de paysages et d'architecture cherchant à expérimenter avec une perspective à 180° dramatique sur un capteur APS-C.
