Panasonic ZS25 vs Pentax K-7

Let's look closer at the Panasonic ZS25 versus Pentax K-7, one is a Small Sensor Superzoom and the other is a Advanced DSLR by competitors Panasonic and Pentax. The image resolution of the ZS25 (16MP) and the K-7 (15MP) is very similar but the ZS25 (1/2.3") and K-7 (APS-C) posses different sensor sizes.

More often than not, it is hard to visualize the difference between sensor dimensions purely by reading technical specs. The pic below will help provide you a far better sense of the sensor sizes in the ZS25 and K-7.

As you can tell, both of these cameras have different resolutions and different sensor dimensions. The ZS25 using its tinier sensor is going to make shooting shallower DOF trickier and the Panasonic ZS25 will offer greater detail using its extra 1MP. Greater resolution will also make it easier to crop images a bit more aggressively. The newer ZS25 provides an advantage when it comes to sensor technology.
