The VR-320 was unveiled 3 years later than the K20D and that is a fairly significant gap as far as camera technology is concerned. Both cameras feature different body design with the Olympus VR-320 being a Compact camera and the Pentax K20D being a Mid-size SLR camera.

Before delving straight to a comprehensive comparison, here is a short highlight of how the VR-320 matches up vs the K20D in regards to portability, imaging, features and an overall rating.

Here is a sample of the gallery pictures for Olympus VR-320 and Pentax K20D. The full galleries are viewable at Olympus VR-320 Gallery and Pentax K20D Gallery.

If you are intending to carry your camera regularly, you will have to think about its weight and measurements.

Taking into consideration dimensions and weight, the portability score of the VR-320 and K20D is 94 and 59 respectively.

Typically, it is tough to imagine the gap in sensor sizing simply by seeing a spec sheet. The photograph below will help give you a far better sense of the sensor dimensions in the VR-320 and K20D.

As you can see, both cameras feature different megapixel count and different sensor sizing. The VR-320 using its smaller sensor is going to make shooting shallower depth of field trickier and the Pentax K20D will produce more detail having an extra 1 Megapixels. Greater resolution will also let you crop images way more aggressively. The younger VR-320 should have an advantage when it comes to sensor technology.
