The Fuji shot was at ISO 400 and both Pentax shots were at ISO 3200.  The fact that one of them looks essentially as good as the Fuji is what's really amazing. Though based on that Fuji shot, I'd say that the 27 f2.8 deserves it's reputation.  It is essentially Fugi's version of the SMC-P FA 4

Eric, if I may add my two cents here. The 28mm is wider that 50-200, so by projecting more (wider angle of view) on the same sensor size (Fuji and Pentax have both sensors of very similar size) - you get an impression of sharper picture. The "livelieness" of the picture is too subjective a term to
