Olympus E-M10 IV vs Sigma DP2 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 Sigma DP2, which was introduced in September 2009 is a Large Sensor Compact camera with a 5.0MP APS-C sensor. As you can see, DP2 is 11 years older than E-M10 IV. Let's see if this age difference between two cameras makes a big difference.

Olympus E-M10 IV vs Sigma DP2: 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 Sigma DP2 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). Sigma DP2 has external dimensions of 113 x 60 x 56 mm (4.45 x 2.36 x 2.2″) and weighs 280 g (0.62 lb / 9.88 oz) (including batteries).

Below you can see the front view size comparison of Olympus E-M10 IV and Sigma DP2. Sigma DP2 is 9mm narrower and 24mm shorter than Olympus E-M10 IV but it is also 7mm thicker. As you can tell, actually this is not a fair size comparison since Sigma DP2 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. Sigma DP2 is significantly lighter (103g ) 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 Sigma DP2 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:
Top Mirrorless Cameras with Weather Sealing
Top Compact Cameras with Weather Sealing

LCD Screen Size and Features

Olympus E-M10 IV's 3.00" LCD screen is slightly larger than Sigma DP2's 2.5" 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, Sigma DP2 has a fixed type screen which provides less flexibility in shooting positions compared to E-M10 IV.
Olympus E-M10 IV vs Sigma DP2: 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, Sigma DP2 has a 5.0MP APS-C (20.7 x 13.8 mm ) sized CMOS (Foveon X3) sensor .

Olympus E-M10 IV's sensor provides 15MP more than Sigma DP2'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 DP2 sensor size comparison.

As seen above, Sigma DP2 has a 1.3x Larger sensor area than Olympus E-M10 IV. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.
