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 D30 and Olympus E-M10 side-by-side from the front, back and top in their relative dimensions. Canon D30 has external dimensions of 109 x 68 x 28 mm (4.29 x 2.68 x 1.1″) and weighs 218 g (0.48 lb / 7.69 oz) (including batteries). Olympus E-M10 has external dimensions of 119 x 82 x 46 mm (4.69 x 3.24 x 1.81″) and weighs 396 g (0.87 lb / 13.97 oz) (including batteries).
Below you can see the front-view size comparison of the Canon D30 and the Olympus E-M10. Canon D30 is clearly the smaller of the two cameras. Its body is 10mm narrower, 14mm shorter and 18mm thinner than Olympus E-M10. As you can tell, actually this is not a fair size comparison since Canon D30 has a built-in lens but Olympus E-M10 doesn't. Once you put a lens on E-M10, its thickness will increase significantly.
Here is the back view size comparison of the Canon D30 and Olympus E-M10.
Now lets look at the top view comparison of Canon D30 and Olympus E-M10.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon D30 is significantly lighter (178g ) than the Olympus E-M10 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 E-M10, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather-sealed body of the D30, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the E-M10.
LCD Screen Size and Features
Canon D30 and Olympus E-M10's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Olympus E-M10 features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels whereas the Canon D30 has a fixed type screen which provides less flexibility in shooting positions compared to E-M10.
