Panasonic 3D1 vs Pentax K-3 Sensor Comparison

More often than not, it is very tough to visualise the difference between sensor sizes purely by reviewing specs. The picture underneath will help offer you a greater sense of the sensor dimensions in the 3D1 and K-3.

As you can plainly see, both the cameras provide different megapixel count and different sensor sizes. The 3D1 using its tinier sensor will make shooting shallower depth of field more challenging and the Pentax K-3 will offer extra detail with its extra 12MP. Higher resolution will also allow you to crop shots more aggressively. The more aged 3D1 is going to be disadvantaged when it comes to sensor innovation.
