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 Olympus SZ-30MR and Canon 60Da side-by-side from the front, back and top in their relative dimensions. Olympus SZ-30MR has external dimensions of 106 x 69 x 40 mm (4.17 x 2.72 x 1.57″) and weighs 226 g (0.50 lb / 7.97 oz) (including batteries). Canon 60Da has external dimensions of 145 x 106 x 79 mm (5.71 x 4.17 x 3.11″) and weighs 755 g (1.66 lb / 26.63 oz) (including batteries).
Below you can see the front view size comparison of Olympus SZ-30MR and Canon 60Da. Olympus SZ-30MR is clearly the smaller of the two cameras. Its body is 39mm narrower, 37mm shorter and 39mm thinner than Canon 60Da. As you can tell, actually this is not a fair size comparison since Olympus SZ-30MR has a built-in lens but Canon 60Da doesn't. Once you put a lens on 60Da, its thickness will increase significantly.
Now lets look at the top view comparison of Olympus SZ-30MR and Canon 60Da.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Olympus SZ-30MR is significantly lighter (529g ) than the Canon 60Da 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 60Da, the total kit will weigh much higher.
Thanks to the weather sealed body of 60Da, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to SZ-30MR.
LCD Screen Size and Features
Olympus SZ-30MR and Canon 60Da's LCD screens has the same diagonal size of 3".
On the other hand, Canon 60Da 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 SZ-30MR's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to 60Da.
