Pentax Efina vs Pentax K-7 Sensor Comparison

Quite often, it is very tough to visualise the difference between sensor sizing only by looking at technical specs. The visual underneath will offer you a far better sense of the sensor measurements in the Efina and K-7.

As you have seen, both the cameras provide different megapixel count and different sensor sizing. The Efina featuring a tinier sensor will make achieving bokeh more challenging and the Pentax K-7 will give you greater detail due to its extra 1 Megapixels. Higher resolution can also let you crop photographs more aggressively. The more recent Efina is going to have an advantage when it comes to sensor tech.
