For this lens, with remarkably high intensity of F1.2, LEICA Camera AG has redefined the name NOCTICRON. The classic medium telephoto lens of 42.5 mm (equivalent to 85 mm for 35 mm cameras) is ideal for portrait photography. The large aperture allows targeted handling of the shallow depth of field. The 9 slats create a round aperture, which provides a particularly beautiful bokeh in the blurred areas of the image. Choose a LEICA DG lens with ultimate optical quality and performance. Naturally, the lenses meet the strict quality standards of Leica Camera AG. Keep motifs simple or spontaneous. Optical Image Stabilization (OIS), a technology built directly into the lens, provides great photos with crisp, blur-free contours in all areas of the image. Do you minimize unwanted light reflections? thanks to the nano-surface coating on the system lenses. This special, ultra-thin coating was developed by Panasonic to reduce disturbing light reflections across the entire light spectrum. The result is crystal clear images even when shooting light sources in the dark.
