Panasonic LZ40 vs Pentax K-7 Sensor Comparison

Normally, it is tough to see the contrast in sensor measurements only by looking through a spec sheet. The visual below will help offer you a better sense of the sensor sizes in the LZ40 and K-7.

Clearly, the two cameras feature different megapixel count and different sensor measurements. The LZ40 because of its smaller sensor will make achieving shallow DOF harder and the Panasonic LZ40 will render greater detail having its extra 5 Megapixels. Greater resolution will also make it easier to crop pics way more aggressively. The newer LZ40 is going to have an advantage when it comes to sensor technology.
