Duplicate of the Panasonic Nocticron 42.5mm — same flagship MFT portrait as ID 3899.
The Panasonic Leica DG Nocticron 42.5mm f/1.2 ASPH. is the fastest autofocus lens available for the Micro Four Thirds system, bearing the Leica DG and Nocticron designations that indicate Leica co-development at an f/1.2 aperture class. It covers an 85mm full-frame equivalent field of view.
The lens delivers 42.5mm (85mm equivalent on MFT) at f/1.2 maximum aperture with ASPH aspherical elements, Power O.I.S. optical image stabilisation, Leica DG optical quality standards, and MFT electronic coupling for full AF and EXIF.
The Nocticron is the definitive MFT portrait lens — an f/1.2 aperture on MFT provides subject isolation that competes with full-frame f/2 equivalents in practical photography. Power O.I.S. supplements in-body stabilisation for handheld use in dim conditions. The Leica DG quality standards ensure the f/1.2 aperture is genuinely useful, not just a specification.
Test AF speed and accuracy for portrait use. Verify Power O.I.S. operation in multiple stabilisation modes. Inspect ASPH element coating. Check aperture blades for oil contamination at f/1.2 where any sluggishness will directly affect bokeh quality.
