Here we are comparing two cameras with different body types: Fujifilm GFX 50S, which was introduced in January 2017 is a Pro Mirrorless camera with a 51.0MP Medium format sensor whereas Pentax K-1, which was introduced in February 2016 is a Semi-Pro DSLR camera with a 36.0MP Full frame sensor.
Despite some fundamental differences of these two body types, Mirrorless cameras are becoming serious alternatives to DSLR cameras thanks to their size/weight advantages and recent improvements in their focus speeds , which makes this comparison even more interesting. Fortunately, you can't go wrong with any of these cameras as we rank them amongst Top 10 cameras in their classes. Fujifilm GFX 50S is ranked #1
out of 38 Pro Mirrorless cameras with an overall score of 100 whereas Pentax K-1 is ranked #3
out of 90 Semi-Pro DSLR cameras with an overall score of 90.
