DESCRIPTION The Leica Thalia prime lenses offer a consistently cinematic look and feel throughout the range of 9 lenses from 24mm to 180mm with an image circle of 60mm. The lenses are incredibly lightweight and compact with a matched front diameter of 95mm and are available in PL mount with /i Technology metadata contacts. The unique always-round iris design creates a bokeh that is smooth, distinct and full of character. And although these are not vintage lenses, the Leica Thalias offer many of the characteristics that have led cinematographers to pair older lenses with digital sensors. They are smooth, forgiving, and clear without being overly sharp.
