First, the biggest factor will be the lens youʻll put on the K-1 II vs. the D5200. But if all things are equal:
a) The K-1 II with 36MP and no anti-aliasing filter vs. D5200 24MP with AA filter.
b) Better low light and/or high ISO performance.
c) Weather sealed, so more likely to continue shooting in poor weather.
d) Brighter and bigger pentaprism vs. pentamirror for your optical view finder.
e) Option for pixel shifting and astrotracer.
The K-1 II is about twice the weight of the D5200 and there is not built-in flash. But in nearly every other category, youʻre going to have a new camera that is much more capable and other than the lens, the main limitation is the skill and eye of the photographer.
