Canon SD4000 IS vs Pentax K-S1

Lets look more in depth at the Canon SD4000 IS and Pentax K-S1, one being a Small Sensor Compact and the other is a Advanced DSLR by manufacturers Canon and Pentax. There is a crucial difference among the sensor resolutions of the SD4000 IS (10MP) and K-S1 (20MP) and the SD4000 IS (1/2.3") and K-S1 (APS-C) provide different sensor sizing.

The SD4000 IS was introduced 5 years prior to the K-S1 and that is a fairly serious gap as far as camera tech is concerned. Both of the cameras feature different body design with the Canon SD4000 IS being a Compact camera and the Pentax K-S1 being a Mid-size SLR camera.

Before getting straight to a step-by-step comparison, here is a concise highlight of how the SD4000 IS matches up vs the K-S1 in relation to portability, imaging, features and an overall grade.

The following is a sample of the gallery pictures for Canon PowerShot SD4000 IS and Pentax K-S1. The whole galleries are provided at Canon SD4000 IS Gallery and Pentax K-S1 Gallery.

Often, it is difficult to imagine the contrast in sensor measurements only by checking out specifications. The visual underneath will offer you a much better sense of the sensor sizes in the SD4000 IS and K-S1.

Plainly, both the cameras feature different resolutions and different sensor measurements. The SD4000 IS using its smaller sensor is going to make getting shallower depth of field more difficult and the Pentax K-S1 will produce extra detail using its extra 10MP. Greater resolution will also help you crop photos way more aggressively. The older SD4000 IS will be behind when it comes to sensor tech.
