Olympus E-M10 IV vs Pentax WG-1: Physical Specs and Body features Comparison

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 E-M10 IV and Pentax WG-1 side-by-side from the front, back and top in their relative dimensions. Olympus E-M10 IV has external dimensions of 122 x 84 x 49 mm (4.8 x 3.31 x 1.93″) and weighs 383 g (0.84 lb / 13.51 oz) (including batteries). Pentax WG-1 has external dimensions of 114 x 58 x 28 mm (4.49 x 2.28 x 1.1″) and weighs 157 g (0.35 lb / 5.54 oz) (including batteries).

Below you can see the front view size comparison of Olympus E-M10 IV and Pentax WG-1. Pentax WG-1 is clearly the smaller of the two cameras. Its body is 8mm narrower, 26mm shorter and 21mm thinner than Olympus E-M10 IV. As you can tell, actually this is not a fair size comparison since Pentax WG-1 has a built-in lens but Olympus E-M10 IV doesn't. Once you put a lens on E-M10 IV, its thickness will increase significantly.

Here is the back view size comparison of Olympus E-M10 IV and Pentax WG-1.

Now lets look at the top view comparison of Olympus E-M10 IV and Pentax WG-1.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day. Pentax WG-1 is significantly lighter (226g ) than the Olympus E-M10 IV 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 IV, the total kit will weigh much higher.

Weather Sealing

Thanks to the weather sealed body of WG-1, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to E-M10 IV.

LCD Screen Size and Features

Olympus E-M10 IV's 3.00" LCD screen is slightly larger than Pentax WG-1's 2.7" screen.

In addition to the size advantage, Olympus E-M10 IV LCD screen also has a Tilting feature where you can change the angle of the screen to make it easier to shoot from waist or over the head levels. On the other hand, Pentax WG-1 has a fixed type screen which provides less flexibility in shooting positions compared to E-M10 IV.
Olympus E-M10 IV vs Pentax WG-1: Sensor Comparison

Olympus E-M10 IV has a 20.0MP Four Thirds (17.4 x 13 mm ) sized CMOS sensor and features TruePic VIII processor. On the other hand, Pentax WG-1 has a 14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor .

Olympus E-M10 IV's sensor provides 6MP more than Pentax WG-1's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely. On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.

Below you can see the E-M10 IV and WG-1 sensor size comparison.
