I own the DA 15 and the Sigma 12-24. The 12-24 does so well on the K3 because it crops out the full frame corners of the Sigma. The corners on the 12-24 on the K-1 is it's weakest point. The main things you will gain with the DA 15 is extreme flare resistance, warmer color rendering, quick shift focus, and of course much smaller size. My DA 21 has better corners than the my DA 15, but the 15 can get shots the 21 can not get without stitching. Whether you would regret the purchase I can not say. I got the 12-24 for the K-1. I would probably look through my shots with the 12-24 and see how many are around 15mm.
