What We Like
+Exceptional compactness: only 9.9mm thick, making it a true micro-pancake lens
+Sharp center and mid-frame performance, suitable for APS-C coverage
+Quality brass construction with beautiful black lacquer finish
+Rangefinder-coupled for accurate Leica M focusing
+Variable aperture f/2.8-f/16 is wider than most comparable pancake lenses
+Affordable price point around $325-359 USD
Worth Knowing
−Significant corner softness and vignetting, especially at wider apertures
−Difficult aperture ring control due to compact size—impossible with gloves
−Not weather-sealed; limited durability for heavy use
−Mirror-equipped cameras cannot use this lens due to rear element depth
