Size and weight are big decision factors when you are trying to find the ideal camera for your needs.
In this section, we are going to illustrate the Olympus 8000 and Pentax Q10 side-by-side from the front, back and top in their relative dimensions. Olympus 8000 has external dimensions of 95 x 62 x 22 mm (3.74 x 2.44 x 0.87″) and weighs 182 g (0.40 lb / 6.42 oz) (including batteries). Pentax Q10 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 the Olympus 8000 and the Pentax Q10. Olympus 8000 is 7mm narrower and 12mm thinner than Pentax Q10 but it is also 4mm taller. As you can tell, actually this is not a fair size comparison since Olympus 8000 has a built-in lens but Pentax Q10 doesn't. Once you put a lens on Q10, 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.
Olympus 8000 is 18g lighter than the Pentax Q10 but we don't think this will make a significant difference.
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 Q10, the total kit will weigh much higher.
Weather Sealing
With its weather-sealed body, we believe that the 8000 has a big advantage over the Q10 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Pentax Q10's 3.00" LCD screen is slightly larger than Olympus 8000's 2.7 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
