Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Panasonic FX48 and Pentax K-7 side-by-side from the front, back and top in their relative dimensions. Panasonic FX48 has external dimensions of 95 x 53 x 22 mm (3.74 x 2.09 x 0.87″) and weighs 150 g (0.33 lb / 5.29 oz) (including batteries). Pentax K-7 has external dimensions of 131 x 97 x 73 mm (5.16 x 3.82 x 2.87″) and weighs 750 g (1.65 lb / 26.46 oz) (including batteries).
Below you can see the front view size comparison of Panasonic FX48 and Pentax K-7. Panasonic FX48 is clearly the smaller of the two cameras. Its body is 36mm narrower, 44mm shorter and 51mm thinner than Pentax K-7. As you can tell, actually this is not a fair size comparison since Panasonic FX48 has a built-in lens but Pentax K-7 doesn't. Once you put a lens on K-7, its thickness will increase significantly.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Panasonic FX48 is significantly lighter (600g ) than the Pentax K-7 which may become a big advantage especially on long walking trips.
Again, this comparison may not be very useful in real life as we are comparing the weight of a camera with a built-in lens to the body-only weight of an interchangeable lens camera. Once you put a lens on K-7, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather sealed body of K-7, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to FX48.
LCD Screen Size and Features
Pentax K-7's 3" LCD screen is slightly larger than Panasonic FX48's 2.5" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
