Olympus E-M10 IV vs Canon 7D 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 7D, which was introduced in November 2009 is a Advanced DSLR camera with a 18.0MP APS-C sensor. As you can see, 7D is 11 years older than E-M10 IV. Let's see if this age difference between two cameras makes a big difference.

Despite some fundamental differences of these two body types, Mirrorless cameras are becoming serious alternatives to DSLR cameras thanks to their size/weight advantages and recent improvements in their focus speeds , which makes this comparison even more interesting.

Olympus E-M10 IV vs Canon 7D: 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 7D 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 7D has external dimensions of 148 x 111 x 74 mm (5.83 x 4.37 x 2.91″) and weighs 860 g (1.90 lb / 30.34 oz) (including batteries).

Below you can see the front view size comparison of Olympus E-M10 IV and Canon 7D. Olympus E-M10 IV is clearly the smaller of the two cameras. Its body is 26mm narrower, 27mm shorter and 25mm thinner than Canon 7D.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day. Olympus E-M10 IV is significantly lighter (477g ) than the Canon 7D which may become a big advantage especially on long walking trips.

Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you have to also take into account the lenses that you will be using with these bodies. Since Canon 7D has an APS-C sized sensor and Olympus E-M10 IV has a smaller Four Thirds sensor, Olympus E-M10 IV's lenses for a similar focal length and aperture will generally be lighter and smaller than the Canon 7D lenses.

LCD Screen Size and Features

Olympus E-M10 IV and Canon 7D's LCD screens has the same diagonal size of 3.00".

On the other hand, Olympus E-M10 IV features a Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over the head levels whereas the Canon 7D has a fixed type screen which provides less flexibility in shooting positions compared to E-M10 IV.
Olympus E-M10 IV vs Canon 7D: 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, Canon 7D has a 18.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features Dual Digic 4 processor.

Below you can see the E-M10 IV and 7D sensor size comparison.

As seen above, Canon 7D has a 1.5x 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.

Olympus E-M10 IV vs Canon 7D Comparison of Available Lenses
Which camera has more lenses?

Number of available lenses is a big decision factor while choosing your interchangeable lens camera. When we look at the available lenses for these two cameras, we see that Canon 7D has an advantage over Olympus E-M10 IV There are 333 lenses for Canon 7D's Canon EF/EF-S mount, on the other hand there are only 120 lenses for Olympus E-M10 IV's Micro Four Thirds lens mount.

Another important factor is the availability of image stabilization. Olympus E-M10 IV has a big advantage in this regard because it has a sensor based image stabilization (IS) which means that all the lenses mounted to this body will be stabilized. E-M10 IV's built-in Image stabilization system is effective to compensate vibration up to 4.5-stops according to CIPA standards.
On the other hand, Canon 7D doesn't have this feature so you have to buy a lens with optical stabilization feature. Currently there are 113 lenses for Canon EF/EF-S mount with Optical Image Stabilization features.
