42mm · f/1.2
The Leica DG Nocticron 42.5mm f/1.2 is a premium Micro Four Thirds portrait lens with excellent optical performance: sharp wide open, with beautiful bokeh, good color and contrast. Build quality is exceptional, all-metal and tank-like, but it is large and heavy compared to alternatives like the Olympus 45mm f/1.8. Weaknesses include high price, no weather sealing, and an aperture ring that only works on Panasonic bodies. It suits photographers seeking the best image quality and a 'Leica look' in the system, willing to pay a premium for speed and build.
