Pentax P70 vs Sony TX55 Sensor Comparison

Sometimes, its difficult to visualize the gap between sensor dimensions just by checking technical specs. The image here might offer you a far better sense of the sensor dimensions in the P70 and TX55.

As you can tell, both of the cameras have got the exact same sensor measurements albeit different MP. You should expect the Sony TX55 to resolve greater detail because of its extra 4 Megapixels. Higher resolution can also make it easier to crop shots much more aggressively. The more aged P70 is going to be disadvantaged with regard to sensor tech.
