Pentax P70 vs Sony W830 Sensor Comparison

To sum up, both of the cameras enjoy the same exact sensor sizing but not the same MP. You should anticipate the Sony W830 to render extra detail due to its extra 8 Megapixels. Greater resolution will also make it easier to crop pics far more aggressively. The more aged P70 will be behind when it comes to sensor tech.
