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 Canon 50D and FujiFilm XP10 side-by-side from the front, back and top in their relative dimensions. Canon 50D has external dimensions of 146 x 108 x 74 mm (5.75 x 4.25 x 2.91″) and weighs 822 g (1.81 lb / 29.00 oz) (including batteries). FujiFilm XP10 has external dimensions of 96 x 64 x 23 mm (3.78 x 2.52 x 0.91″) and weighs 135 g (0.30 lb / 4.76 oz) (including batteries).
Below you can see the front-view size comparison of the Canon 50D and the FujiFilm XP10. FujiFilm XP10 is clearly the smaller of the two cameras. Its body is 50mm narrower, 44mm shorter and 51mm thinner than Canon 50D. As you can tell, actually this is not a fair size comparison since FujiFilm XP10 has a built-in lens but Canon 50D doesn't. Once you put a lens on 50D, its thickness will increase significantly.
Here is the back view size comparison of the Canon 50D and FujiFilm XP10.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
FujiFilm XP10 is significantly lighter (687g ) than the Canon 50D 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 50D, the total kit will weigh much higher.

LCD Screen Size and Features
Canon 50D's 3.00" LCD screen is slightly larger than FujiFilm XP10's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
