Olympus TG-2 iHS vs Pentax K20D

Lets look much closer at the Olympus TG-2 iHS versus Pentax K20D, former being a Waterproof while the latter is a Advanced DSLR by manufacturers Olympus and Pentax. The image resolution of the TG-2 iHS (12MP) and the K20D (15MP) is pretty comparable but the TG-2 iHS (1/2.3") and K20D (APS-C) possess totally different sensor measurements.

The TG-2 iHS was introduced 5 years later than the K20D and that is a fairly large difference as far as camera tech is concerned. The two cameras come with different body type with the Olympus TG-2 iHS being a Compact camera and the Pentax K20D being a Mid-size SLR camera.

Before getting through a in depth comparison, below is a brief synopsis of how the TG-2 iHS scores against the K20D with regard to portability, imaging, features and an overall rating.

If you're intending to carry your camera, you need to factor in its weight and measurements. The Olympus TG-2 iHS has got physical dimensions of 111mm x 67mm x 29mm (4.4" x 2.6" x 1.1") with a weight of 230 grams (0.51 lbs) and the Pentax K20D has proportions of 142mm x 101mm x 70mm (5.6" x 4.0" x 2.8") along with a weight of 800 grams (1.76 lbs).

Bear in mind, the weight of an ILC will vary dependant on the lens you have attached at the time. Underneath is the front view over all size comparison of the TG-2 iHS against the K20D.

Taking into consideration size and weight, the portability grade of the TG-2 iHS and K20D is 91 and 59 respectively.

In many cases, it is difficult to envision the gap in sensor sizing merely by seeing specs. The graphic here may provide you a far better sense of the sensor sizes in the TG-2 iHS and K20D.

As you can plainly see, the two cameras posses different megapixels and different sensor sizing. The TG-2 iHS with its smaller sensor will make getting shallower DOF more difficult and the Pentax K20D will show extra detail using its extra 3MP. Higher resolution will allow you to crop pictures somewhat more aggressively. The younger TG-2 iHS is going to have an advantage in sensor technology.
