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.

The ZS25 was introduced 3 years after the K-7 which is quite a significant gap as far as technology is concerned. Both of the cameras have different body design with the Panasonic ZS25 being a Compact camera and the Pentax K-7 being a Mid-size SLR camera.

Before going straight to a in-depth comparison, here is a simple summary of how the ZS25 matches up vs the K-7 for portability, imaging, features and an overall mark.

This is a sample of the gallery pics for Panasonic Lumix DMC-ZS25 and Pentax K-7. The whole galleries are viewable at Panasonic ZS25 Gallery and Pentax K-7 Gallery.

If you're looking to travel with your camera often, you will want to think about its weight and size.

Keep in mind, the weight of an Interchangeable Lens Camera will vary based on the lens you have at the time. Underneath is a front view dimensions comparison of the ZS25 compared to the K-7.

Factoring in dimensions and weight, the portability score of the ZS25 and K-7 is 93 and 60 respectively.

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.
