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 Olympus E-M5 II and Panasonic ZS45 side-by-side from the front, back and top in their relative dimensions. Olympus E-M5 II has external dimensions of 124 x 85 x 45 mm (4.88 x 3.35 x 1.77″) and weighs 469 g (1.03 lb / 16.54 oz) (including batteries). Panasonic ZS45 has external dimensions of 108 x 60 x 32 mm (4.25 x 2.36 x 1.26″) and weighs 249 g (0.55 lb / 8.78 oz) (including batteries).
Below you can see the front-view size comparison of the Olympus E-M5 II and the Panasonic ZS45. Panasonic ZS45 is clearly the smaller of the two cameras. Its body is 16mm narrower, 25mm shorter and 13mm thinner than Olympus E-M5 II. As you can tell, actually this is not a fair size comparison since Panasonic ZS45 has a built-in lens but Olympus E-M5 II doesn't. Once you put a lens on E-M5 Mark II, its thickness will increase significantly.
Here is the back view size comparison of the Olympus E-M5 II and Panasonic ZS45.
Now lets look at the top view comparison of Olympus E-M5 II and Panasonic ZS45.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic ZS45 is significantly lighter (220g ) than the Olympus E-M5 II 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-M5 Mark II, the total kit will weigh much higher.
Weather Sealing
With its weather-sealed body, we believe that the E-M5 Mark II has a big advantage over the ZS45 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Olympus E-M5 II and Panasonic ZS45's LCD screens have the same diagonal size of 3.00 inches.
Panasonic ZS45 features a
Tilting-only screen which is mostly only good for shooting from waist or over-the-head levels. On the other hand, Olympus E-M5 II sports a
Fully Articulated screen which is more flexible and useful, especially for taking selfies and video.
