Olympus TG-320 vs Pentax K-r

Lets look a bit more closely at the Olympus TG-320 and Pentax K-r, one being a Waterproof and the latter is a Entry-Level DSLR by competitors Olympus and Pentax. The sensor resolution of the TG-320 (14MP) and the K-r (12MP) is pretty well matched but the TG-320 (1/2.3") and K-r (APS-C) enjoy different sensor dimensions.

Generally, it is difficult to imagine the gap between sensor measurements simply by looking at a spec sheet. The photograph underneath may give you a more clear sense of the sensor sizes in the TG-320 and K-r.

Clearly, both cameras have got different megapixel count and different sensor measurements. The TG-320 using its tinier sensor is going to make achieving shallow depth of field harder and the Olympus TG-320 will give you greater detail because of its extra 2MP. Higher resolution will also enable you to crop photographs much more aggressively. The newer TG-320 should have an advantage when it comes to sensor innovation.
