Panasonic ZS45 vs Pentax K-7 Sensor Comparison

Sometimes, it is very difficult to visualise the difference between sensor sizing only by reading through specs. The photograph below might give you a better sense of the sensor sizes in the ZS45 and K-7.

All in all, the two cameras feature different resolutions and different sensor sizing. The ZS45 because of its tinier sensor will make achieving shallow depth of field more difficult and the Panasonic ZS45 will give you more detail utilizing its extra 1MP. Greater resolution will make it easier to crop images way more aggressively. The younger ZS45 will have a benefit when it comes to sensor innovation.
