Pentax Efina vs Pentax K-S1 Sensor Comparison

Generally, it is very difficult to visualise the gap between sensor sizes purely by reading specifications. The image underneath should offer you a clearer sense of the sensor sizes in the Efina and K-S1.

Plainly, both cameras feature different megapixels and different sensor sizes. The Efina having a tinier sensor will make achieving shallower depth of field more challenging and the Pentax K-S1 will deliver extra detail with its extra 6 Megapixels. Greater resolution will let you crop images way more aggressively. The more aged Efina is going to be behind in sensor innovation.
