What We Like
+Exceptional sharpness at f/1.0 wide-open for an ultra-fast lens, with significant improvements over the Leica Noctilux f/0.95 especially at close distances
+Grinding aspherical (GA) front element with high-refractive glass enables compact size (55mm) and outstanding optical performance
+Smooth, well-built all-metal construction with tactile aperture and focus rings; excellent mechanical quality with no flex
+Beautiful bokeh rendered through 12 aperture blades and floating elements; organic, ethereal image rendering
+Low-light capability with f/1.0 maximum aperture; outstanding performance for shallow depth of field and night photography
Worth Knowing
−Heavy at 482-484g; substantial lens requiring sturdy support when hand-held
−Pronounced outward field curvature and high optical vignetting causing uneven background rendering depending on subject distance
−Slight focus shift noticeable when stopping down from f/1.4 to f/2.0, requiring caution when relying on rangefinder focusing
−No autofocus or image stabilization; manual focus only limits usability for some photographers and shooting scenarios
