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 Casio EX-FC100 and Pentax Q7 side-by-side from the front, back and top in their relative dimensions. Casio EX-FC100 has external dimensions of 100 x 59 x 23 mm (3.94 x 2.32 x 0.91″) and weighs 156 g (0.34 lb / 5.50 oz) (including batteries). Pentax Q7 has external dimensions of 102 x 58 x 34 mm (4.02 x 2.28 x 1.34″) and weighs 200 g (0.44 lb / 7.05 oz) (including batteries).
Below you can see the front view size comparison of Casio EX-FC100 and Pentax Q7. Casio EX-FC100 is 2mm narrower and 11mm thinner than Pentax Q7 but it is also 1mm taller. As you can tell, actually this is not a fair size comparison since Casio EX-FC100 has a built-in lens but Pentax Q7 doesn't. Once you put a lens on Q7, 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.
Casio EX-FC100 is significantly lighter (44g ) than the Pentax Q7 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 Q7, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither Casio Exilim EX-FC100 nor Pentax Q7 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.

Pentax Q7's 3" LCD screen is slightly larger than Casio EX-FC100's 2.7" screen.
