Canon EF 17-40mm f/4L USM 17-40mm
Doté d’une ouverture constante f/4 sur la plage 17-40mm et d’une construction tropicalisée de série L, il combine 3 lentilles asphériques et 1 élément à ultra-faible dispersion pour une netteté homogène. Son autofocus USM silencieux et son filetage de 77mm facilitent l’usage de filtres, tandis qu’une mise au point minimale de 279mm autorise des gros-plans créatifs. Idéal pour les photographes de voyage et de paysage, il reste moins indiqué pour le portrait en raison de son ouverture f/4.
