Pentax Efina vs Pentax K-S2 Sensor Comparison

Quite often, it's difficult to imagine the gap between sensor measurements only by reviewing specifications. The photograph below should provide you a greater sense of the sensor measurements in the Efina and K-S2.

Plainly, the 2 cameras have got different megapixels and different sensor measurements. The Efina due to its tinier sensor is going to make achieving shallow DOF more challenging and the Pentax K-S2 will offer greater detail as a result of its extra 6MP. Greater resolution can also help you crop pics much more aggressively. The older Efina is going to be behind when it comes to sensor technology.
