42.5mm · f/1.2
The Leica Nocticron 42.5mm f/1.2 is a premium micro four thirds portrait lens with excellent build quality, featuring all-metal construction and a smooth aperture ring. Optically, it delivers outstanding sharpness, color, and contrast wide open, with smooth bokeh. However, it is large, heavy, and expensive. The aperture ring does not work on Olympus bodies. It suits enthusiasts seeking top-tier image quality and a Leica-like rendering, despite the high cost and size.
