What We Like
+Exceptionally compact pancake design at 21.9mm length and 137g weight for maximum portability
+Sharp, detailed image rendering from center to edge with minimal aberrations and excellent flare control
+Outstanding 0.4m minimum focusing distance rare for M-mount compact lenses, enabling close-up compositions
+Premium brass construction with lacquered finishes available in Pearl White, Matte Black, and Silver
+Excellent distortion control at only 0.462% with minimal vignetting for architectural and landscape photography
+8-blade aperture creates distinctive octagonal starburst effects for artistic night photography
Worth Knowing
−Relatively high vignetting figures typical of ultra-compact pancake lenses (around 3 EV at maximum aperture)
−Limited depth of field at 28mm with f/2.8 aperture restricts shallow depth-of-field creative effects
−Non-clicking aperture ring without visible top markings makes precise aperture adjustment somewhat fiddly
−Rotating filter thread when adjusting aperture can complicate filter use and composition changes
