Olympus VG-145 vs Pentax K20D

Its time to look a little more closely at the Olympus VG-145 and Pentax K20D, one being a Ultracompact and the other is a Advanced DSLR by competitors Olympus and Pentax. The sensor resolution of the VG-145 (14MP) and the K20D (15MP) is fairly well matched but the VG-145 (1/2.3") and K20D (APS-C) provide totally different sensor sizes.

The VG-145 was announced 3 years later than the K20D and that is quite a significant gap as far as technology is concerned. The two cameras feature different body design with the Olympus VG-145 being a Ultracompact camera and the Pentax K20D being a Mid-size SLR camera.

Before going straight to a in-depth comparison, here is a brief highlight of how the VG-145 matches up against the K20D when it comes to portability, imaging, features and an overall grade.

For anyone who is looking to lug around your camera frequently, you will need to think about its weight and measurements. The Olympus VG-145 has external measurements of 96mm x 57mm x 19mm (3.8" x 2.2" x 0.7") and a weight of 120 grams (0.26 lbs) whilst the Pentax K20D has proportions of 142mm x 101mm x 70mm (5.6" x 4.0" x 2.8") with a weight of 800 grams (1.76 lbs).

Remember that, the weight of an Interchangeable Lens Camera will vary dependant on the lens you choose at the time. Below is a front view physical size comparison of the VG-145 compared to the K20D.

Considering dimensions and weight, the portability rating of the VG-145 and K20D is 96 and 59 respectively.

Typically, it is very tough to visualise the gap between sensor measurements merely by looking at technical specs. The visual underneath will help provide you a more clear sense of the sensor measurements in the VG-145 and K20D.

As you can tell, each of these cameras feature different megapixel count and different sensor measurements. The VG-145 using its tinier sensor will make shooting shallower depth of field more difficult and the Pentax K20D will resolve greater detail with its extra 1MP. Greater resolution can also help you crop pics way more aggressively. The more modern VG-145 will have an edge with regard to sensor innovation.
