Not sure if this has been posted here before. But if it hasn't, it might be of interest particularly for the K-1 users out there.
Pretty nice portrait, actually:

More samples - and comparisons - are needed to determine the characteristic rendering style of that new lens, I guess. Will it render more like a modern hypercorrected design, prioritizing corner-to-corner resolution at the expense of losing microcontrast, 3-D, and muted blues and greens, or will it manage to be a modern interpretation of "old school" Pentax virtues: microcontrast, "pixie dust", punchy "memorial" colours, with lush blues and greens?
To my mind, Ricoh shouldn't attempt to copy Sigma's lifeless Art Series rendering, but maybe that's just me.
At any rate, enjoy.
