The Panasonic Leica DG Nocticron 42.5mm f/1.2 is a fast prime lens that features a stepping motor AF system for smooth and silent focusing for video recording. The f/1.2 maximum aperture is suitable for low light shooting and for portraits with a pleasing blurry background. Its all-metal design and manual aperture ring gives this lens a retro feel and the optical image stabilization ensures sharpness by minimizing camera shake. It sports the sophisticated optics you'd expect from the Leica branding and features a POWER O.I.S. system that is compatible with Lumix G cameras' Dual I.S. functionality for extra shake compensation. The small form factor is suitable for portable micro four thirds setups. The focal length of this lens is ideal for portraits and also for any subject where separation from the background is key.
