I just ordered the 25mm pana-leica f1.4, not sure if I'm having second thoughts or not but it was tough deciding between it and the sigma 30mm f1.4. I figure 25mm is the better more versatile focal length, but now that I'm looking at videos on youtube, the sigma seems to do better in lowlight/night shooting, with it seeming a tad noiser on the PL. Tough making decisions sometimes. I do prefer the rendering of the leica, and both seem to have excellent sharpness.
