Here we are comparing two cameras with different body types: Olympus E-P5, which was introduced in October 2013 is a Entry-Level Mirrorless camera with a 16.0MP Four Thirds sensor whereas Pentax K-S2, which was introduced in February 2015 is a Entry-Level DSLR camera with a 20.0MP APS-C 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. Olympus E-P5 is ranked #7
out of 100 Entry-Level Mirrorless cameras with an overall score of 76 whereas Pentax K-S2 is ranked #2
out of 79 Entry-Level DSLR cameras with an overall score of 81.
