Olympus E-M10 IV vs Canon G7 X MIII Comparison Overview

Here we are comparing two cameras with different body types: Olympus E-M10 IV, which was introduced in August 2020 is a Entry-Level Mirrorless camera with a 20.0MP Four Thirds sensor whereas Canon G7 X MIII, which was introduced in July 2019 is a Large sensor compact camera with a 20.0MP 1' sensor. There is 13 months difference between E-M10 IV and G7 X MIII so we don't expect to see a huge technology difference between these two cameras but it would still give an advantage to younger E-M10 IV, especially in sensor tech.

Olympus E-M10 IV vs Canon G7 X MIII: 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 Canon G7 X MIII 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). Canon G7 X MIII has external dimensions of 105 x 61 x 41 mm (4.13 x 2.4 x 1.61″) and weighs 304 g (0.67 lb / 10.72 oz) (including batteries).

Below you can see the front view size comparison of Olympus E-M10 IV and Canon G7 X MIII. Canon G7 X MIII is clearly the smaller of the two cameras. Its body is 17mm narrower, 23mm shorter and 8mm thinner than Olympus E-M10 IV. As you can tell, actually this is not a fair size comparison since Canon G7 X MIII 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.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day. Canon G7 X MIII is significantly lighter (79g ) 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

Unfortunately neither Olympus OM-D E-M10 IV nor Canon PowerShot G7 X Mark III provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors. If weather sealing is a must-have feature for you, check these sections:
