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 SP-100 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 SP-100 has external dimensions of 122 x 91 x 133 mm (4.8 x 3.6 x 5.25″) and weighs 594 g (1.31 lb / 20.95 oz) (including batteries).
Below you can see the front-view size comparison of the Canon 70D and the Olympus SP-100. Olympus SP-100 is 17mm narrower and 13mm shorter than Canon 70D but it is also 54mm thicker. As you can tell, actually this is not a fair size comparison since Olympus SP-100 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 SP-100.
Now lets look at the top view comparison of Canon 70D and Olympus SP-100.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus SP-100 is significantly lighter (161g ) 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.
Weather Sealing
With its weather-sealed body, we believe that the 70D has a big advantage over the SP-100 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Canon 70D and Olympus SP-100's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Canon 70D 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. Olympus SP-100's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to 70D.
