What We Like
+Exceptional f/1.2 aperture delivers excellent low-light performance and beautiful shallow depth-of-field effects
+Compact and lightweight design (10.6 oz) with 20% reduction in size compared to previous versions
+Outstanding image quality with four aspherical surfaces and reduced aberrations even at full aperture
+Durable all-metal construction with professional build quality and precise rangefinder coupling
+12-blade iris for smooth, circular bokeh and creamy out-of-focus rendering
+Versatile focus range: 0.5m minimum focus in live view mode for digital flexibility
Worth Knowing
−Larger physical profile than typical M-mount lenses, potentially unbalanced on some rangefinder bodies
−Significant vignetting at f/1.2 aperture, particularly noticeable at wide open settings
−Noticeable chromatic aberration and fringing at maximum aperture on high-contrast edges
−Lens hood sold separately; limited sharpness improvement in extreme corners even when stopped down
