As far as size goes, the Pentax K-S2 is 1mm narrower and 6mm shorter than the Nikon D5500. However, it is also 3mm thicker. Despite the size difference, the Nikon D5500 is significantly lighter. It weighs 258g less than the Pentax K-S2.
The Nikon D5500 has a 24.0MP APS-C (23.5 x 15.6 mm ) sized CMOS sensor and features an Expeed 4 processor. Meanwhile, the Pentax K-S2 has a 20.0MP APS-C (23.5 x 15.6 mm ) sized CMOS sensor and features the PRIME MII processor.
What both sensors have in common, outside of the APS-C, is that both the Pentax K-S2 and Nikon D5500 sensors lack anti-alias (Low-Pass) filters. Moreover, they provide the same level of control over the depth of field when used with same focal length and aperture.
However, since the Pentax K-S2 has a 20% larger pixel area (18.37µm2 vs 15.28µm2) compared to the Nikon D5500, it has the potential to have less noise in low light / High ISO images.
