Olympus TG-610 vs Pentax K20D

Let's take a closer look at the Olympus TG-610 versus Pentax K20D, one being a Waterproof and the other is a Advanced DSLR by competitors Olympus and Pentax. The sensor resolution of the TG-610 (14MP) and the K20D (15MP) is very well matched but the TG-610 (1/2.3") and K20D (APS-C) possess different sensor dimensions.

The TG-610 was brought out 2 years later than the K20D and that is quite a big gap as far as tech is concerned. Both of the cameras come with different body type with the Olympus TG-610 being a Compact camera and the Pentax K20D being a Mid-size SLR camera.

Before getting in to a comprehensive comparison, below is a brief introduction of how the TG-610 grades versus the K20D with regard to portability, imaging, features and an overall rating.

Here is a sample of the gallery pics for Olympus TG-610 and Pentax K20D. The entire galleries are provided at Olympus TG-610 Gallery and Pentax K20D Gallery.

In case you're planning to carry your camera frequently, you will want to factor in its weight and volume.

Looking at size and weight, the portability grade of the TG-610 and K20D is 93 and 59 respectively.

Often, it can be difficult to picture the gap between sensor sizing simply by looking at specifications. The graphic below will provide you a clearer sense of the sensor sizes in the TG-610 and K20D.

Plainly, both the cameras posses different resolutions and different sensor sizing. The TG-610 due to its tinier sensor is going to make getting shallower DOF tougher and the Pentax K20D will resolve more detail having its extra 1MP. Greater resolution can also make it easier to crop pics somewhat more aggressively. The more modern TG-610 should have a benefit with regard to sensor tech.
