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 70D and Olympus TG-860 side-by-side from the front, back and top in their relative dimensions. Canon 70D has external dimensions of 139 x 104 x 79 mm (5.47 x 4.11 x 3.09″) and weighs 755 g (1.66 lb / 26.63 oz) (including batteries). Olympus TG-860 has external dimensions of 110 x 64 x 28 mm (5.12 x 2.52 x 1.1″) and weighs 224 g (0.49 lb / 7.90 oz) (including batteries).
Below you can see the front-view size comparison of the Canon 70D and the Olympus TG-860. Olympus TG-860 is clearly the smaller of the two cameras. Its body is 29mm narrower, 40mm shorter and 51mm thinner than Canon 70D. As you can tell, actually this is not a fair size comparison since Olympus TG-860 has a built-in lens but Canon 70D doesn't. Once you put a lens on 70D, its thickness will increase significantly.
Here is the back view size comparison of the Canon 70D and Olympus TG-860.
Now lets look at the top view comparison of Canon 70D and Olympus TG-860.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus TG-860 is significantly lighter (531g ) than the Canon 70D 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 70D, the total kit will weigh much higher.

Canon 70D and Olympus TG-860's LCD screens have the same diagonal size of 3.00 inches.
Olympus TG-860 features a
Tilting-only screen which is mostly only good for shooting from waist or over-the-head levels. On the other hand, Canon 70D sports a
