In many cases, its tough to visualize the difference in sensor sizing merely by viewing specifications. The visual underneath will give you a greater sense of the sensor sizes in the SZ-31MR iHS and K-S2.

Plainly, both of those cameras have got different megapixel count and different sensor sizing. The SZ-31MR iHS using its smaller sensor is going to make shooting shallower depth of field harder and the Pentax K-S2 will render extra detail using its extra 4MP. Greater resolution can also enable you to crop images much more aggressively. The older SZ-31MR iHS will be behind with regard to sensor innovation.
