Canon SX510 HS vs Pentax K20D

In this write-up, we are looking at the Canon SX510 HS and Pentax K20D, former is a Small Sensor Superzoom while the other is a Advanced DSLR by companies Canon and Pentax. The sensor resolution of the SX510 HS (12MP) and the K20D (15MP) is fairly well matched but the SX510 HS (1/2.3") and K20D (APS-C) enjoy different sensor measurements.

The SX510 HS was announced 5 years after the K20D which is quite a serious difference as far as tech is concerned. Both cameras offer different body type with the Canon SX510 HS being a Compact camera and the Pentax K20D being a Mid-size SLR camera.

Before delving straight into a in depth comparison, below is a short overview of how the SX510 HS matches up against the K20D in the way of portability, imaging, features and an overall score.

The following is a sample of the gallery pictures for Canon PowerShot SX510 HS & Pentax K20D. The whole galleries are provided at Canon SX510 HS Gallery & Pentax K20D Gallery.

For those who are looking to carry around your camera, you're going to have to consider its weight and dimensions. The Canon SX510 HS provides outer dimensions of 104mm x 70mm x 80mm (4.1" x 2.8" x 3.1") having a weight of 349 grams (0.77 lbs) and the Pentax K20D has dimensions of 142mm x 101mm x 70mm (5.6" x 4.0" x 2.8") along with a weight of 800 grams (1.76 lbs).

Take into consideration, the weight of an ILC will change based on the lens you have chosen at the time. The following is the front view dimension comparison of the SX510 HS and the K20D.

Taking into consideration size and weight, the portability score of the SX510 HS and K20D is 80 and 59 respectively.

Usually, its difficult to imagine the gap between sensor sizes purely by checking specifications. The pic here should provide you a stronger sense of the sensor dimensions in the SX510 HS and K20D.

Plainly, both of the cameras offer different megapixel count and different sensor sizes. The SX510 HS using its tinier sensor is going to make achieving shallower DOF harder and the Pentax K20D will give you extra detail with its extra 3 Megapixels. Greater resolution can also enable you to crop photos a little more aggressively. The newer SX510 HS should have an edge with regard to sensor technology.
