The FS7 was unveiled 13 months earlier than the 645D which makes them a generation apart from each other. Both of these cameras feature different body design with the Panasonic FS7 being a Ultracompact camera and the Pentax 645D being a Large SLR camera.

Before diving straight to a thorough comparison, here is a brief summation of how the FS7 grades vs the 645D with regard to portability, imaging, features and an overall rating.

For those who are intending to carry your camera regularly, you are going to need to take into account its weight and dimensions.

Often, it is very difficult to visualize the contrast between sensor sizing merely by looking at a spec sheet. The visual here may provide you a much better sense of the sensor dimensions in the FS7 and 645D.

Clearly, both cameras feature different resolutions and different sensor sizing. The FS7 with its tinier sensor is going to make getting shallow depth of field tougher and the Pentax 645D will give extra detail having an extra 30MP. Higher resolution will allow you to crop shots way more aggressively. The older FS7 is going to be behind in sensor innovation.
