Olympus 7040 vs Pentax K-3 II Sensor Comparison

As you can plainly see, both of the cameras enjoy different resolutions and different sensor sizes. The 7040 due to its smaller sensor will make shooting shallow depth of field more challenging and the Pentax K-3 II will provide more detail as a result of its extra 10MP. Greater resolution will also enable you to crop pics far more aggressively. The more aged 7040 will be behind in sensor technology.
