This seems to be getting a positive response here so I figured I'd submit it. Supercell thunderstorms in the central U.S. are photogenic, but not often do they show the texture and structure shown in this example. I shot this storm with both the K-5 at 16mm and a Fuji X-E3 at 12mm (using the excellent Samyang 12/2), and I preferred the rendering from the K-5, even with the 8 MP difference. This was a reason why I decided to stick with Pentax for the foreseeable future, since I mostly do storm photography.
