TAMRON 18-270 mm f/3.5-6.3 Di II VC PZD - Objectif pour Canon
13 August 2011
Excerpt: un bon objectif de voyage mais de moyenne qualité. vignetage et abération chromatique trop présente un point dur lorsque on manœuvre le zoom. je regrette mes objectifs canon 18-55 et 55-250 que j'ai vendu pour l'acquisition de celui ci.
Pros: large amplitude focale
Cons: vignetage et abération chromatique trop présente, manque de souplesse du zoom
