What We Like
+Stunning bokeh with creamy, soft out-of-focus rendering at wide apertures for portraiture
+Improves significantly when stopped down with modern coatings and glass providing sharp results by f/5.6
+Beautiful chrome and brass construction evokes 1950s-60s aesthetic while being modern and reliable
+E46 filter compatibility and 0.7m close focus are practical improvements over original versions
+Exceptional handling with tactile aperture clicks and smooth focus ring
+Synthesizes best optical characteristics of original versions I, II, and III pre-ASPH designs
Worth Knowing
−Soft focus wide open at f/1.4 makes critical focusing challenging, unlike modern ASPH versions
−Susceptible to focus shift and not as corner-sharp as modern lenses even when stopped down
−Clip-on hood design less secure than screw-thread alternatives and easily lost
−Limited supply at launch and premium price of $3,895 reflects collector-grade positioning

Read our notes on general
Leica's reissued Summilux-M 50mm f/1.4 combines the most desirable aspects of versions I, II, and III of the legendary 50mm Lux with modern manufacturing techniques, glass elements, and lens coatings. While the body design follows the version I with a normal scallop, the optical formula follows that of version II and III. The lens delivers creamy, smooth, cinematic bokeh that "melts" backgrounds into a watercolor-like wash with natural gradual fall-off and beautiful 3D pop. Stopped down to even f/5.6 the lens matches the performance of a modern 50mm lens, if not as sharp overall as the APO-Summicron-M 50mm f/2.0.
