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 Fujifilm X-E1 and Canon SX40 HS side-by-side from the front, back and top in their relative dimensions. Fujifilm X-E1 has external dimensions of 129 x 75 x 38 mm (5.08 x 2.95 x 1.5″) and weighs 350 g (0.77 lb / 12.35 oz) (including batteries). Canon SX40 HS has external dimensions of 123 x 92 x 108 mm (4.84 x 3.62 x 4.25″) and weighs 600 g (1.32 lb / 21.16 oz) (including batteries).
Below you can see the front view size comparison of Fujifilm X-E1 and Canon SX40 HS. Fujifilm X-E1 is 17mm shorter and 70mm thinner than Canon SX40 HS but it is also 6mm wider. As you can tell, actually this is not a fair size comparison since Canon SX40 HS has a built-in lens but Fujifilm X-E1 doesn't. Once you put a lens on X-E1, its thickness will increase significantly.
Here is the back view size comparison of Fujifilm X-E1 and Canon SX40 HS.
Now lets look at the top view comparison of Fujifilm X-E1 and Canon SX40 HS.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Fujifilm X-E1 is significantly lighter (250g ) than the Canon SX40 HS 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 X-E1, the total kit will weigh much higher.
Unfortunately neither Fujifilm X-E1 nor Canon PowerShot SX40 HS provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Fujifilm X-E1's 2.8" LCD screen is slightly larger than Canon SX40 HS's 2.7" screen.
On the other hand, Canon SX40 HS sports a Fully Articulated screen
which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over the head levels, and especially very useful for shooting selfies and video. On the other hand, Fujifilm X-E1 has a fixed type screen which provides almost no flexibility in shooting positions compared to SX40 HS.
