More often than not, it's difficult to visualize the gap between sensor sizing just by going over technical specs. The photograph below will give you a greater sense of the sensor sizes in the SZ-31MR iHS and K-7.

As you can tell, each of the cameras enjoy different megapixel count and different sensor sizing. The SZ-31MR iHS using its tinier sensor is going to make shooting bokeh harder and the Olympus SZ-31MR iHS will offer extra detail having an extra 1MP. Higher resolution can also enable you to crop pictures far more aggressively. The more recent SZ-31MR iHS should have an advantage when it comes to sensor technology.
