Pentax K5IIs - SMCP-FA 31mm f/1.8 ASPH Limited ISO80 f/1.8 1/1250th

Pentax K5IIs - Sigma 18-35mm f/1.8 ART @ 21mm ISO 80 f/1.8 1/2500th*

Pentax K5IIs - Sigma 18-35mm f/1.8 @35mm f/1.8 ISO 320 1/160th

* After doing a very rough comparison of the Sigma 18-35mm f/1.8 ART @ 21mm I can say even though the zoom lens is faster (f/1.8 Vs f/2.4) this gives it has no particular advantage over the DFA21 when it comes to OOF rendering. The zoom lens can be very unpredictable in its OOF rendering: varying from superbly good, to Japanese eyeball torture. The DFA21mm f/2.4 is very consistent in its output, Also the DFA21 is designed for full frame and thus can be used on the K-1 without the severe vignetting the Sigma Art zoom gets @ 21mm.
