Samsung ST90 vs Sigma SD15 Sensor Comparison

More often than not, its tough to visualize the contrast between sensor sizes simply by reading through technical specs. The pic underneath may provide you a far better sense of the sensor dimensions in the ST90 and SD15.

As you can tell, both of the cameras have different megapixels and different sensor sizes. The ST90 with its tinier sensor is going to make shooting shallower depth of field more challenging and the Samsung ST90 will give extra detail using its extra 9 Megapixels. Greater resolution can also let you crop photos a bit more aggressively. The fresher ST90 should have an advantage with regard to sensor innovation.
