Panasonic's flagship MFT portrait prime — the Leica DG Nocticron 42.5mm f/1.2 with OIS.
The Panasonic Leica DG Nocticron 42.5mm f/1.2 ASPH. Power O.I.S. is the flagship portrait lens for the Micro Four Thirds system. Released in 2013, it provides an 85mm equivalent with an ultra-fast f/1.2 aperture — the fastest prime in the MFT system. The Nocticron name echoes Leica's Noctilux, and the lens is co-designed with Leica for optical excellence.
Optical performance is outstanding — the finest portrait lens in the MFT ecosystem. Sharpness is excellent from f/1.2. The aspherical elements provide outstanding correction. Bokeh is exceptionally smooth and beautiful. The f/1.2 on MFT provides DOF separation equivalent to approximately f/2.4 on full frame. Power O.I.S. adds effective stabilisation.
Micro Four Thirds mount. Filter thread is 67mm. Weight is approximately 425 grams — compact for the specification. Build quality is outstanding with full metal construction and Leica branding. The Power O.I.S. works alongside body IBIS for Dual I.S. on compatible Panasonic bodies. Autofocus is fast and accurate for portrait work.
Available on the used market at moderate prices. Check AF, OIS, and clean optics. The finest portrait lens for MFT — the f/1.2 speed, Leica optical design, and OIS stabilisation create an extraordinary combination. The 85mm equivalent with this level of quality and speed is why many MFT photographers stay with the system.
