How about the Pentax K1 having a smaller pixels and better dynamic range than the Canon 5D mark III ?

For a given sensor size more pixels are smaller, but they are more pixels hopefully collaborate together, they kinda "help each other" in making the final image :-)

Digital sensors are all mostly ISO invariant, meaning that the latitude peaks around 150-300 ISO, and then drops as the ISO setting gets higher than 400. Over the years, I came to the conclusion that the key to good image result came down to keep ISO rather low within a limited range, and that the resolution of the sensor was secondary. Keeping ISO within a low range is achieved by using fast enough lenses, flash strobes or the use of a good tripod, given that lighting is fixed by external conditions that are independent from the camera system we are using. For photographing moving subjects, such as for wedding, tripod or SR aren't valid options, use of faster lenses or strobes help a lot to keep ISO within a low range. The actual difference of sensor latitude between various sensors is something like 0.3ev to 0.5ev, that is not much compared to being able to have 2 stop of extra latitude by using a lens with f2.8 max aperture instead of a lens with f5.6 aperture. The same is true when shooting with a f1.4 lens vs f2.8, two stops of exposure difference returns a more significant step up in image quality compared to the small difference between two camera models.
