The 1 was revealed 5 years later than the K20D and that is quite a big gap as far as tech is concerned. Both of the cameras offer different body type with the Olympus 1 being a SLR-like (bridge) camera and the Pentax K20D being a Mid-size SLR camera.

Before delving in to a comprehensive comparison, below is a simple summation of how the 1 scores against the K20D when considering portability, imaging, features and an overall rating.

Following is a sample of the gallery pics for Olympus Stylus 1 and Pentax K20D. The full galleries are viewable at Olympus 1 Gallery and Pentax K20D Gallery.

Oftentimes, it is very tough to visualise the difference between sensor sizing simply by reading through specifications. The visual underneath might offer you a greater sense of the sensor sizes in the 1 and K20D.

To sum up, both cameras enjoy different megapixels and different sensor sizing. The 1 with its tinier sensor will make getting shallower depth of field tougher and the Pentax K20D will resolve more detail because of its extra 3 Megapixels. Greater resolution will also let you crop photos far more aggressively. The fresher 1 will have a benefit with regard to sensor technology.
